Introduction

In order to comply with the requirements of the Animal Welfare Act (TierSchG) regarding the keeping of domestic geese, the Council of Europe’s recommendations on domestic geese are taken into account alongside the general provisions of the Animal Welfare Regulation for Farm Animals (TierSchNutztV). There are currently no further binding specific regulations in Germany.

To give concrete form to the Council of Europe’s recommendations, an agreement has been reached in Lower Saxony that specifies the husbandry requirements for domestic geese.

The so-called ‘Goose Husbandry Agreement’ is an agreement between the Lower Saxony Ministry of Food, Agriculture and Consumer Protection (ML) and the Lower Saxony Poultry Industry Association (NGW) on minimum requirements for the rearing and fattening of geese. It is also used as a guide in other federal states outside Lower Saxony.

Under this agreement, livestock keepers undertake to comply with the minimum requirements for goose husbandry set out therein. These apply to herds of over 100 fattening geese and cover both rearing and fattening.

In accordance with Section 2(3) of the Animal Welfare Act (TierSchG), the animal keeper must possess the relevant knowledge and skills to ensure the appropriate feeding, care and species-appropriate housing of the animals, and must provide evidence of this expertise to the competent authority upon request.

According to the Goose Husbandry Agreement, the following are accepted as proof of expertise

  • a successfully completed training course as a farmer or livestock manager, with specific focus on poultry farming (e.g. ‘Inter-farm training in poultry farming’ at the Ruthe Teaching and Research Farm of the University of Veterinary Medicine Hannover Foundation) or
  • a successfully completed degree in agricultural sciences or veterinary medicine, or
  • the independent rearing of geese over at least three fattening cycles, involving no fewer than 100 geese, without any complaints regarding animal welfare from the competent authority.

In cases of doubt regarding expertise in individual cases, the competent authority may require proof of such expertise during a technical consultation. This document is intended to impart expertise in the field of fattening goose rearing. It may be used as part of inter-farm training or for self-study, e.g. as preparation for the aforementioned technical consultation.

Behaviour of fattening geese

The wild ancestor of today’s European domestic goose breeds is the greylag goose (Anser anser). Over the course of domestication, domestic geese have undergone a number of changes compared to their wild counterparts, affecting both their appearance and behaviour. As a result of increases in body size and weight, domestic geese have become flightless. In terms of behaviour, they are less shy. However, the animals’ behaviour is fundamentally genetically determined, and their rearing environment should be adapted to this as closely as possible. If existing behaviours are suppressed by rearing conditions, this can lead to considerable psychological and physical stress for the animal.

Behavioural patterns can be divided into so-called functional groups (e.g. locomotor behaviour), which are expressed within the respective functional area (e.g. pasture).

Functional group vs. functional area

  • Functional circuit: A behavioural system organised according to functional, goal-oriented principles, involving corresponding coordination of movement
  • Functional area: The spatial area of the postural system in which one (or more) functional circuits are performed

The following section discusses the behaviour of the wild/original form. Any deviations or distinctive features resulting from modern methods of fattening geese are also noted.

Reproductive behaviour is not discussed in detail, as fattening geese are slaughtered before reaching sexual maturity.

Functional area

  • Running surfaces
  • Areas where straw is spread
  • Pasture

Geese have strong legs set wide apart and angled slightly inwards, which enables them to move about easily on land. They move only slowly. They are good swimmers thanks to their long, broad build, their large, air-filled bones and the webbing between their toes.

Functional areas

  • Feeding area/watering point
  • Open water sources
  • Pasture

Feed intake

Geese are predominantly herbivores. Under natural conditions, geese consume part of their food in the water. They do this by dabbling and sifting, much as can be observed in ducks.

On land, the birds are able to pluck grass and green plants effectively with their strong beaks, though they also cause significant browsing damage. When feeding, their sense of touch plays a key role. Due to the shape of their beaks, they prefer moist grain to dry grain, as it is easier to consume. Thanks to their expandable oesophagus, which functions like a crop, geese can consume a relatively large amount of food in a short time.

Water absorption

To drink, the beak is lowered horizontally onto the water’s surface so that the tip of the beak is slightly submerged. The beak opens and closes in rapid movements, after which the head is jerked upwards and the water is swallowed. Alternatively, the goose submerges two-thirds of its beak directly into the water and then lifts its head to swallow the water. Sifting movements of the beak are also performed.

Functional areas

  • Open water activities
  • Fenced-off area
  • Pasture

Grooming behaviour refers to the wide range of behaviours that contribute to the cleaning and maintenance of the plumage, as well as to thermoregulation, and enhance well-being. These activities are particularly observed after the morning meal and account for approximately 10–15% of the total daily time. On the one hand, comfort behaviour serves the purpose of personal grooming; on the other hand, some movements also serve as signals (e.g. raising the wings whilst simultaneously straightening and rearing up the body as a display of pride or to impress).

Comfort behaviourCharacteristics
Shaking
  • Removal of water or dirt from the plumage
  • Compensatory behaviour, particularly after a stamping action
  • Shaking the body, shaking the wings, shaking the head, shaking the tail, shaking the legs, spreading the wings (The goose stands upright, holds its tail parallel to the ground and fans it out widely. The beak points upwards and the goose flaps its wings rapidly and noisily. It stands with its feet stretched out.)
Stretching
  • Before and after falling asleep, whilst preening and after standing for a long time
  • Stretching wings upwards, stretching wings and legs
Preening behaviour
  • Geese have a complex series of individual preening movements that keep their plumage clean and functional. Soiled plumage in individual birds may be an indication of an underlying illness.
  • Spreading the oil from the uropygial gland over the entire body helps to make the plumage water-repellent.
  • If an open body of water is available, the birds also use it to clean their nostrils and eyes.
Bathing behaviour
  • Water-specific behaviours include, for example, scooping water (the goose uses its head and neck in a rapid upward movement to bring water onto its back) and splashing (the goose strikes the water’s surface vigorously with its wings) or combinations thereof, as well as diving (not for food).
  • Bathing behaviour is naturally performed both with and without water. During dry bathing, the same sequence of movements can be observed as when bathing in water.

 

Functional areas

  • Area where hay is spread
  • Pasture

Geese usually rest or sleep after every substantial meal. When resting on land, they usually stand on one leg. On the water, they paddle from time to time to prevent themselves from drifting ashore. When sleeping on land, their bodies lie on the ground. They tuck their heads into their shoulder feathers or pull them back onto their backs, resting their beaks on their chests.

At night or in the shed, geese rest in large groups; during the day, they also rest together in smaller groups. Resting (sitting/standing) accounts for over 50% of all their behaviour.

Functional areas

  • Area where hay is spread
  • Pasture

The social structure of geese is more tightly knit than that of ducks. A flock of geese always moves as a group. In the wild, leadership falls to the strongest gander. In modern commercial goose farming, this social structure is usually no longer as pronounced.

In goslings, imprinting after hatching is particularly strong compared to other poultry species. The hierarchy is established within the first few days.

The animals’ acoustic signals are also part of their behavioural expressions and play an important role in their communication with one another, e.g. the chirping of goslings, alarm or warning calls, hissing as a sign of agitation, etc.

Animal-friendly management of the herd and individual animals

Note

Guidance on the care of domestic geese can be found in Appendix 1,

Management recommendations for the management of domestic geese (Geese Management Agreement).

Animal care and welfare: the responsibilities of pet owners

The animal owner or carer must check on the animals’ welfare at least twice a day by observing them directly.

To develop a positive relationship between humans and animals, contact with the animal must take place frequently and in a calm manner, right from the very first days of life. It should be borne in mind that goslings react to calls or human voices.

Animal-friendly management of the herd

When carrying out any work in the barn, the geese must be handled calmly to avoid startling the animals when approaching them and causing unnecessary agitation within the flock:

  • Avoid abrupt, hasty movements
  • No prolonged or sudden loud noises
  • No sudden, intense light

The geese should be gently accustomed to the regular performance of certain tasks.

  • The intensive imprinting behaviour of this species can be utilised, particularly when handling goslings.
  • The geese must always be herded calmly and slowly. Any obstacles that could injure the geese should be removed beforehand.

Before entering the shed, the geese should be ‘warned’ by knocking on the door or speaking to them. The geese can be accustomed to your own voice.

Do not attempt to catch geese hastily from within the flock. If individual birds need to be removed from the flock (e.g. for weighing), this should be done from a small group that has previously been separated from the flock using herding boards.

When spreading litter mechanically, a person should walk in front of the litter spreader to drive the geese and remove any animals unable to walk from the path. The further procedure is set out in the section on ‘Handling individual animals’.

  • Prior animal checks ensure that no animals unable to walk are present in the shed. 

The animals should be accustomed to the relevant machinery from the start of rearing.

Animal-friendly treatment of individual animals

Geese must not be caught or lifted by their legs or a wing, in order to prevent injury, particularly to their hocks.

“It is prohibited to drag or pull animals by the head, ears, horns, legs, tail or fur, or to handle them in such a way as to cause them unnecessary pain or suffering” (see Regulation (EC) No 1/2005, Annex 1, Chapter III, No 1.8(d)).

  • Due to their physique, geese are usually handled gently by the neck when being caught. Lifting them by the head or neck is not permitted.

To handle individual birds or when an animal needs to be carried, the goose is lifted with both hands by the body or at the base of both wings. To carry the bird, one arm is placed around the body to support the weight and keep the wings in a closed position. The other hand grips the upper neck to prevent the goose from biting (occupational safety).

Geese must not be carried suspended upside down.

Injured, sick or suffering animals whose continued presence in the flock would cause avoidable suffering must be immediately separated from the flock for treatment in a quarantine pen (ensure unrestricted access to water and feed!) or humanely euthanised.

  • See section 2.6 of the Goose Husbandry Agreement on rearing and fattening
  • Dead geese must be removed from the shed or outdoor area without delay, stored appropriately in refrigerated carcass containers and disposed of in accordance with regulations.

 

Housing requirements and management

The rearing of fattening geese is divided into the rearing phase and the subsequent fattening phase.

The rearing of goslings covers the first four weeks of life. This usually takes place in the barn. However, in dry and warm weather, goslings just a few days old can already be taken outdoors for a few hours at a time.

This is followed by the fattening of the geese. Here, fattening methods are distinguished according to the duration of fattening and divided into early fattening (up to approx. 9 weeks of age), medium fattening (up to approx. 16 weeks of age) and late fattening (up to 21–32 weeks of age).

Preparing the stable

The cleaned and disinfected rearing shed is heated to a temperature of at least 30 °C before the chicks are brought in. At least two to three days should be allowed for this. Care must be taken to ensure that the floor and the walls of the shed are also preheated. There are radiant heaters in the shed to ensure that the chicks receive sufficient heat during the first few days.

The functionality of the feeding and watering equipment is checked. The drinkers are rinsed beforehand. In the first few days, additional dip drinkers and feed trays are also set up.

Straw, preferably chopped, is used as bedding, to a depth of approx. 10 cm. This corresponds to roughly 2.5–3.0 kg/m². The straw must be clean and hygienically sound. Wood shavings may also be used.

Settling the animals in

The animals arrive at the farm as day-old chicks from the hatchery in special transport crates. They should then be placed in their pens quickly but calmly.

The animals are placed near feed and water. Due to their high heat requirements, the goslings are initially housed under heat lamps or in small heated pens or chick rings.

The rapid growth of the goslings requires a swift adjustment of the space available to the animals (Goose Husbandry Agreement, as of 03/2020):

Age of the animals (weeks) Max. number of animals/m² of usable housing or shelter area
1 20
2 10
3 6
4–10 4.5
from 11 2
Fattening 2.5

​​​​​​​The German Animal Welfare Association recommends a maximum stocking density of 2 animals per square metre from the fourth week of life.

Stable temperature

Young lambs are very sensitive to temperature in the first few days. The room temperature should be around 25 °C, but the nest temperature (under the heat lamps) must be approximately 35 °C. The temperature is always measured at the animals’ level. From the fifth day of life onwards, the temperature is gradually reduced.

When setting the temperature, it is essential to pay close attention to the birds’ behaviour and their distribution, and to make adjustments at an early stage if necessary.

At around three weeks of age, the goslings are less sensitive to heat and cold.

Humidity

The relative humidity in the barn should never fall below 55%. Levels above 70% should be avoided.

Ventilation/Harmful gases

Fattening geese are usually kept in naturally ventilated houses. They are relatively tolerant of draughts. However, air speeds exceeding 0.3 m/s at animal height should not be exceeded.

In forced-ventilated houses, the minimum air flow rate should be 4.5 m³/kg live weight/hour to ensure adequate ventilation in summer.

The maximum levels of harmful gases are shown in the table below and should not be exceeded (Goose Husbandry Agreement, as of 03/2020):

Harmful gas Max. concentration per m³ of air
Ammonia <10 ppm, not exceeding 20 ppm continuously
CO <3,000 ppm

 

Lighting

Lighting in the barn should be uniform throughout. The lighting schedule may vary during the acclimatisation period in the first three days. It is recommended that the light period be increased to 24 hours during the first few days to allow the animals to become accustomed to the feeding and watering facilities. Thereafter, a day/night rhythm as close to natural as possible should be maintained, and a continuous period of darkness of at least 8 hours must be ensured, provided that there is a deviation from the natural, seasonally varying periods of darkness.

Emergency lighting of max. 2 lux can serve as a guide at night.

Feed management and water supply

Water

A constant supply of fresh and hygienically safe drinking water must be ensured for the animals. The drinking trough should be positioned in such a way that young animals cannot enter or fall into it, thereby avoiding the risk of hypothermia. In rearing, animals are generally supplied with water via round troughs, but nipple drinkers may also be provided at this stage.

In the first few days, bowls of water or slip-on drinkers should also be placed in the shed.

The requirements for drinking facilities during rearing are set out in the following table (practical data provided as a guide, Goose Husbandry Agreement, as of 03/2020):

Age of animals (weeks) Drinking trough (cm) per animal
1–4 0.5
5–9 0.5
10–28  0.75

The height of the drinking troughs should be adjusted according to the age and size of the animals. Nipple drinkers should be easily accessible to the animals with their necks stretched out. For drinking troughs or round troughs, the upper edge should be at the animals’ back height.

 

Additional water supply (Goose Husbandry Agreement, as of March 2020)

As waterfowl, access to water is vital for geese. Open drinking troughs must therefore be provided at all times, even in outdoor enclosures*. Access to an outdoor run and to water for bathing is necessary to allow the geese, as waterfowl, to behave in accordance with their biological needs. Where such access is not possible, the geese must be provided with a sufficient number of water facilities, which must be designed so that the water covers at least the head and can be taken in with the beak, enabling the geese to pour water over their bodies without difficulty. Every goose must have the opportunity to submerge its head under water (see Art. 11(2) of the Council of Europe recommendations). A water supply adapted to the animal’s development must be provided by the start of fattening at the latest.

  • In the view of the German Animal Welfare Association, a bathing facility must be provided to which the geese have constant access and in which they can swim or at least submerge themselves up to their chests. However, this bathing facility may be located indoors if this is necessary from a disease control perspective (see Section 3 of the Avian Influenza Control Ordinance).

* In accordance with Section 3(2) of the Avian Influenza Ordinance, it must be ensured that the animals are not watered using surface water to which wild birds have access.

Food

The recommended usable trough side length and the recommended animal-to-feeding area ratio for batch feeding are set out in the table below (Goose Husbandry Agreement, as of March 2020).

Age (weeks) Usable trough length (cm) per feeding place / animal-to-feeding-place ratio for bulk feeding
1–4 4 / max. 20 :1
5–9 8 / max. 15 : 1
10–28  10 / max. 15 : 1

It is recommended that foals be offered additional feed in feeding troughs on the floor during the first few days of life.

As the animals grow very quickly in the first three weeks, intensive feeding is necessary. The energy content of the starter feed is approximately 11.5 MJ ME and the crude protein content is around 20%. From the fourth or fifth week of life, the crude protein content is reduced to approximately 16%.

Daily routine tasks

The animals and their housing conditions should be checked several times a day, but at least twice a day. Particularly in the first few days after the foals have been brought into the stables, intensive and attentive care is required, with more frequent checks, for which sufficient time should be set aside.

Important parameters include (see also the chapter on animal health parameters):

  • Distribution of animals in the barn
  • Feed and water intake behaviour
  • Movement
  • Condition of the plumage
  • Faecal consistency
  • Condition of the eyes and nostrils

Fresh straw must be added daily. In rearing, this is usually done by hand.

Water and feeding equipment must be checked daily to ensure they are in working order, and any animal losses must be recorded. Furthermore, it would be helpful to document daily feed and water intake in order to identify irregularities in consumption at an early stage. These can, for example, indicate that the animals are unwell. In practice, however, recording feed and water consumption is often difficult, particularly on smaller farms.

The animals should be accustomed to farm noises and machinery, such as the wheel loader, at an early stage. Day-old chicks show less fear than animals that arrive at the farm at a later stage.

If several age groups are kept on the farm, younger animals should be attended to before older ones, and healthy flocks before those showing signs of illness or potential disease, in order to minimise the risk of spreading pathogens.

Special projects

This includes tasks that are not carried out on a daily basis but are performed with a certain degree of regularity during or following a fattening cycle. These include, for example, the cleaning and disinfection work required during the service period (see Chapter 9), the maintenance of the outdoor run (see Chapter 7), care provided by the vet, and examinations to be carried out, such as drinking water tests when using water from the farm’s own well.

Vaccinations

Vaccinations can be used to protect against various infectious diseases. Unlike chickens and turkeys, there is currently no compulsory vaccination requirement for geese. It is standard practice to vaccinate parent birds before the start of the laying period (e.g. against parvovirus) in order to protect young goslings through maternal antibodies. However, depending on the risk of infection and the individual farm structure (e.g. different age groups, various poultry species on the farm), vaccination may also be advisable for fattening geese. Vaccination programmes should always be developed in consultation with the vet responsible for the flock.

Criteria for assessing animal health

Overall impression of the herd

(including animal behaviour)

  • Normal behaviour of the animals:
    • Active
    • Alert
    • Reaction to the presence of people through chattering and movement
    • No geese in the flock show clinical symptoms indicative of illness or injury
  • The animals are not crouching (no tucked-in head)
  • No conspicuous noises (e.g. sneezing/wheezing)
  • No noticeable movement disorders
  • No ‘circling’ (In a panic situation, the flock runs frantically in circles. This poses a risk of crushing, particularly for younger animals. Such behaviour can be triggered, for example, by predators entering the animal enclosure.)

Anomalies in the distribution of animals across the usable area

  • Even distribution across the available area in accordance with their herd behaviour
  • No crowding
  • No animals crowding against the outer walls

Note

Since the foals are already resting together in groups, this natural behaviour must be distinguished from the formation of tightly packed clusters caused by excessively cool temperatures.

Feed consumption

  • Rapid growth and plumage development require that the birds are provided with a diet tailored to their needs, particularly during the rearing phase. Adequate feed intake is essential for meeting daily nutritional requirements and should therefore always be monitored.
  • From the 6th week of life, the animals can be offered an additional portion of grain, e.g. in the form of whole oats. This promotes the development of the gizzard.
  • Feed consumption per animal is influenced by several factors, such as temperature or feed quality, but also by the fattening method.
Table 1: Average feed consumption of pasture-reared geese per animal per day (DLG kompakt, 09/2021)

Age (weeks)

Concentrate Cereals Grass
1–3 90 g starter - 150 g
4–7 50 g Finishing feed 100 g 500 g
from 8 - 80–100 g > 1000 g  

Water consumption

  • Clean, fresh water must be made available to the animals via the drinking troughs. Water is an essential component of the body and plays a role in many metabolic processes. It therefore plays a vital role, particularly in the development of young animals, but also during the later stages of fattening. Some of the water is also taken in through feed. 
  • Water consumption depends on the outside or barn temperature (in summer, a significantly higher water intake by the animals is to be expected), on the dry matter content of the feed and, in particular, on the watering technology.

Animal mobility and activity

  • Mobile
  • Sure-footed gait without movement disorders
  • Ability to stand, ability to walk

Type of breathing

  • Unobtrusive:
    • With its beak closed
    • Without visible effort
    • Without breathing sounds (e.g. wheezing)

Condition of the skin and plumage

  • Clean
  • Age-appropriate
    • From the 6th week of life, the gosling is fully feathered and has completed the transition from down to adult plumage
    • From the 9th week of life, the first juvenile moult begins
    • Subsequently, at intervals of about 7 weeks during further development, the secondary plumage is replaced
    • In adult birds, a complete moult takes place after the end of each breeding season, during which the entire plumage is gradually replaced
  • Well-groomed (not ruffled or matted)
  • Water-repellent (not soaked)
  • No injuries / intact
  • No feather pecking or cannibalism

Condition of the legs (misalignment), ability to walk

  • Ability to walk, steady gait
  • Ability to stand (no bow legs or knock-knees)
  • No misalignment

Paddle health

  • Unbroken skin
  • None / at most minor, superficial changes
  • No colour variations
  • Inspection of the paddles from all sides (particularly the underside)

Abnormalities affecting the eyes

  • Clean
  • Not sticky / no discharge
  • Shiny
  • No redness of the conjunctiva
  • No swelling around the eyes

Abnormalities of the nostrils

  • Clean
  • Unbound / free
  • Unobtrusive breathing (with beak closed, no breathing sounds)

Stool consistency

  • Dark greenish-brown / greyish-brown (depending on diet), formed with a white uric acid cap
  • Brown, paste-like (mustard-like) faeces without a cap of uric acid (caecal faeces, passed up to twice a day)
  • Not thin and mushy / watery, not frothy, not bloody, without worms

Weight trends

  •  Consistent within a group of the same age
Table 2: Feed consumption of the ‘Eskildsen Schwere’ beef hybrids (Golze, 2005)
Week of life Average weight per animal (kg)
3 1.45
8 5.10
9 5.45
16 7.00
22 7.90

Ectoparasites

  • Free from ectoparasites (mites, feather mites, fleas)

Quality of bedding

  • Perfectly hygienic
  • Dry
  • Clean
  • Loose, no clumping
  • Low dust
  • Visibly free from fungal growth

Animal losses

  • Losses throughout the entire rearing cycle (up to 16 weeks of age) should be less than 5%.
    • During the rearing phase (weeks 1–4), losses should be below 2%.

Avian Influenza Regulation (Section 4(1) and (2))

(1) If, within a 24-hour period, losses of

  1. at least three animals within 24 hours in a herd or a spatially defined part of a herd comprising up to and including 100 animals, or
  2. more than 2 per cent of the animals in a flock or spatially defined part of a flock of more than 100 animals, or if there is a reduction in the usual laying performance or average weight gain of more than 5 per cent in each case, the keeper, subject to paragraph 2, must immediately have a veterinarian rule out the presence of infection with the highly pathogenic or low pathogenic avian influenza virus by means of appropriate tests.

(2) If, in a flock or a geographically defined part of a flock in which only ducks and geese are kept, over a period of more than four days

  1. losses amounting to more than three times the usual mortality rate of the animals in the flock or the spatially defined part of the flock, or
  2. a reduction in the usual weight gain or laying performance of more than 5 per cent

, the keeper shall immediately have a veterinarian rule out the presence of infection with the highly pathogenic or low pathogenic avian influenza virus by means of appropriate tests.

Note

If any abnormalities are detected, immediate action must be taken to prevent or minimise any adverse health effects on the herd and to optimise husbandry conditions. If, during a herd inspection, a herd disease is suspected or severely ill individual animals with an unclear clinical picture are identified, the attending veterinarian should be consulted promptly for further diagnostic investigation.

Caring for sick and injured animals

Animal Welfare Act (Section 1: General Principles, Section 1)

  • The purpose of this Act is to protect the life and welfare of animals, based on humanity’s responsibility towards them as fellow creatures. No one shall, without reasonable cause,
    • cause pain
    • suffering or
    • harm

Animal Welfare Ordinance

The animal keeper must immediately rectify any defects in the facilities that adversely affect the animals’ welfare, or take appropriate measures to protect the animals.

Any dead animals found must be removed immediately (see Section 4(1) sentence 1 no. 2 of the Animal Welfare (Livestock) Ordinance), stored properly and disposed of (see the Animal By-products Disposal Act (TierNebG)).

All technical facilities necessary for animal health and welfare (lighting, ventilation and supply systems) must be checked for proper functioning at least once a day. Emergency power generators and alarm systems must be checked for proper functioning at technically required intervals (see Section 4(1) sentence 1 no. 5 of the TierSchNutztV).

The results of the checks must be recorded daily in the barn log (see Section 4(2) of the TierSchNutztV).

At appropriate intervals, the barn, bedding storage areas and feed silos must be thoroughly cleaned and effectively disinfected in accordance with good professional practice (see Section 4(1) sentence 1 no. 10 TierSchNutztV); effective rodent and pest control must be ensured.

Identifying sick and injured animals

  •  Basis: Check the barn at least twice a day
    • Careful observation of the animals, for which sufficient time must be allowed
    • Pay particular attention to areas where weaker animals tend to congregate (e.g. corners of the barn and areas under or next to feeding/watering facilities)

→ Early detection of sick and injured animals

Taking appropriate measures

  • In order to decide whether an animal should be removed from the herd, taken to a holding pen or euthanised, it must first be caught and examined.
  • Once the animal has been caught, a decision must be made as to whether it can remain in the herd, whether there is a ‘reasonable cause’ for culling, or whether the animal can be moved to the isolation pen and returned to the group after an appropriate recovery period or treatment.
  • If there is a prospect of recovery, the animal must be taken immediately to a holding pen with dry and soft bedding or a soft surface.
  • Any animal which, based on a professional assessment of its physical condition, is unlikely to survive must – in accordance with the applicable Animal Welfare Slaughter Ordinance (TierSchlV) – be stunned in a manner consistent with animal welfare and killed immediately, and must not be placed in a separation pen.
  • Where necessary, immediate measures must be taken for treatment and, where appropriate, a veterinarian must be consulted (Section 4(1) sentence 1 no. 3 TierSchNutztV).
  • Where necessary, measures such as the direct provision of water and, where appropriate, feed, as well as wound care using covering, wound-healing sprays (e.g. zinc sprays) or treatment with further medication, must be provided for the animals in the isolation pen.
  • Close monitoring of the course of the disease is required, which, depending on the circumstances, should exceed the minimum monitoring frequency of ‘twice daily’.
  • Any animal in a quarantine pen whose health, according to expert assessment, shows no improvement within a reasonable period of time must be anaesthetised and killed in accordance with animal welfare standards. The animal keeper must ensure that the person carrying out the killing of the animals possesses up-to-date knowledge and skills relevant to animal welfare – including humane methods of stunning and killing (see Section 4(1) of the Animal Welfare Act).
  • Reintegration: Isolated animals should be allowed to socialise again immediately after full recovery.

DLG Leaflet 477 ‘Handling sick and injured domestic and farm poultry’ provides guidance on deciding when a sick animal should be euthanised and when there is a chance of recovery.

separation compartment

  • Already available / can be set up immediately if required
  • Space that can be expanded if required
  • Optimal supply of food and water
    • Fully accessible, even for animals with limited mobility
    • Unrestricted access to fresh feed and water in clean troughs / drinking troughs
  • Sturdy partition from the herd
  • Good hygiene, regular cleaning of the facilities and surfaces
  • Regular replacement of bedding
  • Optimal ambient temperature for the animal, free from draughts
  • In isolation pens, the requirements of the Animal Welfare Ordinance (TierSchNutztV) must be observed.
  • Injured geese or geese that do not pose a risk of infection should not be placed alone in a isolation pen.

Legal basis (emergency killing)

  • Where an animal must be killed, the legal basis for this is provided by the Animal Welfare Act (TSchG), Regulation (EC) No 1099/2009 on the protection of animals at the time of killing, and the Animal Slaughter Ordinance (TierSchlV).
  • ‘Emergency killing’ is defined as ‘the killing of injured animals or animals suffering from a disease that causes severe pain or suffering, where there is no other practicable means of alleviating such pain or suffering’ (Article 2(d) of Regulation (EC) No 1099/2009).
  • A vertebrate animal may only be killed under effective pain relief (stunning) in a state of unconsciousness and insensitivity, or otherwise, insofar as is reasonable under the given circumstances, only in a manner that avoids pain. (Section 4(1) TierSchG)
  • Persons who, on a professional or commercial basis, regularly anaesthetise or kill vertebrates for the purpose of killing must provide the competent authority with proof of competence. (Section 4(1a) Animal Welfare Act)
  • Knowledge and skills regarding legal and technical requirements and methods of killing are necessary.
  • The animal keeper must ensure that the person carrying out the killing of the animals possesses the necessary expertise, including the requisite skills.
  • There is a reasonable ground for emergency killing if
    • the animal has been suffering from severe, incurable pain for a prolonged period.
    • the animal is suffering from a serious illness with no prospect of recovery.
    • the animal is unable to take in food or water independently and is therefore no longer able to care for itself.

Under Regulation (EC) No 1099/2009 and the German Animal Welfare Slaughter Ordinance, emergency slaughter refers to the killing of injured animals or animals suffering from a disease that causes severe pain or distress, where there is no other practicable way to alleviate such pain or distress. It must be carried out as soon as possible.

Under Section 1 of the Animal Welfare Act, no one may cause pain, suffering or harm to an animal without reasonable cause. The killing of animals is only permitted if there is a reasonable cause. This must be weighed up for each individual animal.

Only a person who possesses the necessary knowledge and skills may kill a vertebrate animal.

Procedure for humane euthanasia

Geese identified as requiring slaughter must be killed as soon as possible to avoid unnecessary pain and suffering. The goose to be slaughtered must be handled calmly and gently until the anaesthetic takes effect, to prevent the animal from becoming agitated. Every goose must be stunned before slaughter. Immediately after successful stunning, the animal must be killed using a suitable method (the standard practice is neck breaking). The functionality of the equipment to be used must be checked before each use. Stunning and slaughter should not be carried out in the middle of the flock and, where possible, without causing distress to the other animals.

Procedure

  1. Capturing the animal to be killed
  2. Restraining
    • Restricting the animal’s movement so that it cannot evade the procedure and the stunning can be carried out safely. From an animal welfare perspective, a suitable area outside the barn (e.g. an antechamber) should be used for stunning and killing.
  3. Stunning
    • Every vertebrate must be rendered unconscious and insensitive to pain before slaughter.
    • The effectiveness of the stunning must be checked before killing:
      • No breathing
      • Pupils dilated / no blinking
      • Touching the eye elicits no reaction (no longer any eyelid closure reflex)
      • Neck muscles flaccid
      • Beak opens easily
      • No vocalisation
      • No directed movements
      • No vigorous wing flapping
  4. Killing
    • Killing must follow immediately after stunning.
    • Killing must be carried out competently and safely, without delay and without causing fear or pain to the animal concerned.
    • The onset of death is carefully monitored:
      • A palpable gap between the head and cervical vertebrae and
      • No eyelid reflex (the eye remains open when a finger is brought close to it)
      • No breathing
      • No directed movements
    • If breathing, eye reflexes or directed movements are observed after killing, the killing procedure must be repeated (if necessary, after re-anaesthetising – see Checking anaesthesia)
  5. Disposal
    • It must be ensured that the animal is dead before the carcass is disposed of.
    • Carcasses must be disposed of immediately and securely in the carcass storage facility.

Permitted methods of stunning

Up to 5 kg live weight

  • A sufficiently forceful, targeted blow to the head may be used as a stunning method for poultry weighing up to 5 kg. It must be delivered using a hard, blunt and heavy object appropriate to the size of the animal. The object must be brought towards the animal’s head, rather than the animal being brought towards the object.

No weight limit

  • Penetrating bolt gun
  • Non-penetrating bolt shooting
  • Electrical stunning

 

Note

The equipment used must be designed for this purpose and be suitable for the size of the animal. It must also be in perfect working order and maintained in accordance with the regulations.

Note

Geese aged 8–9 weeks may already weigh over 5 kg and must be stunned using the permitted stunning methods set out above.

Permitted methods of killing (TSchlV)

  • Destruction of the spinal cord by neck break (fracture of the cervical spine between the skull and the first cervical vertebra)
    • Permitted manually for animals weighing less than 3 kg (The neck is hyperextended with a sudden movement of the hand, severing the spinal cord directly behind the head.)
    • using forceps (mechanical, designed so that the spine can be severed quickly and safely without great effort) for animals weighing 3 kg or more
  • Blood drainage (not recommended for disease control reasons)
  • Electrical cardiac arrest

Outdoor access management for fattening geese

Apart from a few full-time farms in the regions of Germany typically associated with goose farming, goose fattening in this country is predominantly carried out as a sideline to farming for direct marketing, with the animals reared outdoors. A sufficiently large outdoor grazing area should be provided for this purpose. From the 9th week of life at the latest, when the geese are fully feathered, they can be reared exclusively on pasture. A practical approach is to allow young goslings access to a green and dry outdoor area for a few hours at a time from as early as the 2nd or 3rd week of life, provided the weather is good. Here, the young birds find fresh greenery and herbs such as chickweed, which they readily eat. Once the geese are fully feathered, they can also be kept outdoors at night and during periods of bad weather. However, it is advisable to house the geese at night in a familiar, covered shelter with bedding. According to Lower Saxony’s ‘Goose Husbandry Agreement’, an outdoor area of at least 10 m² (permanent pasture) per animal should be available; in a rotational grazing system, at least 4 m². Programmes such as ‘Geese from Farm-Raised Free-Range’ even require 15 m² of vegetated and structured area per animal. The NEULAND guidelines for species-appropriate goose husbandry stipulate a minimum of 20 m² per animal for rotational and static grazing.

The pasture/outdoor area must be available to the animals throughout the entire fattening period and can contribute significantly to a needs-based and cost-effective diet for the animals. Accordingly, particular attention should be paid to the maintenance and design of the outdoor area. With intensive use of the pasture by 500 or more animals per hectare of agricultural land (LF), there is increasing wear and tear on the sward. 50–70 m² of grassland per goose is required to keep them on a fully vegetated area all year round. The requirements for a good and robust goose pasture are shown in Table 3.

Soil
  • light to medium-heavy without waterlogged subsoil, with a pH value of 5.0–5.5
  • Clay loam and clay soils with a pH of 6.0
Vegetation
  • 70–80% grasses
  • 10–15% white clover
  • 10–20% herbs
Grass sward
  • closed, dense
Growth height
  • 10 cm, maximum 15 cm
Other requirements
  • Availability of shade

<figcaption>Table 3: Conditions for an optimal goose pasture (Schneider et al., 2002)</figcaption>

The goose spends most of its time outdoors. Even during the final fattening phase, the goose should remain in its familiar surroundings. If the goose has been accustomed to free-range conditions throughout its life, fattening the animals in a shed is difficult; similarly, separating the group in autumn can lead to problems. As geese react very sensitively to changes in location, their environment should not be altered. Although final fattening in a shed is possible, the transition from free-range to purely shed-based rearing causes the animals enormous stress. The aim should therefore be to provide the animals with optimal conditions on pasture all year round.

Structure of the outlet

Adequate shade is particularly important during the hot summer months. Shelters must be provided for this purpose, but trees and shrubs are also suitable for providing shade. These also serve to protect against aerial predators, which pose a particular risk to young foals in their first few weeks.

Appropriate fencing of the outdoor enclosure, e.g. using a wildlife fence with an electrified wire, provides protection against other predators such as foxes and martens and, depending on the region, also against wolves. To ensure a constant supply of fresh water and, where necessary, feed for the animals, appropriate feed and water provisions must be maintained in the outdoor area in accordance with the Goose Husbandry Agreement. In accordance with Section 3 of the Ordinance on Protection against Avian Influenza (GeflPestSchV), the feed and water points must be designed in such a way that wild birds cannot access them. To protect the outdoor run, it is recommended that the water points for the geese be moved at regular intervals. Providing enrichment materials is not necessary where access to the outdoor area is provided.

Maintenance measures

The forage requirement per bird and fattening cycle is approximately 140 kg for a late-fattening goose weighing 7–8 kg. The strain placed on the pasture by the birds is considerable. The birds cause deep browsing damage, and their highly corrosive droppings can also damage the sward, which may lead to a one-sided plant community. A rotational grazing system can provide a solution here, which is easily implemented by moving a mobile electric fence. On the other hand, due to their lower body weight compared to other farm animals and their large feet, the pressure on the ground is lower, which proves advantageous in some locations, particularly damp ones.

Maintaining the pasture therefore involves, where possible, a regular rotation of the area or, if necessary, ploughing. Particularly in late autumn and winter, when the pasture areas have been grazed down and are heavily worn, a rotational grazing system is advisable if sufficient land is available. The principle of rotational grazing, whereby the area is expanded every 3–4 days, has also proven effective.

When reseeding or sowing new crops, it is advisable to use mixtures containing grasses that geese enjoy eating. These include German ryegrass, red fescue, red fescue, as well as white clover, Swedish clover or dandelion. Less favoured are smooth oatgrass, cocksfoot or meadow grass, as well as field alfalfa, red clover and many wild herbs. The location influences the choice of varieties. Some plants pose a risk of poisoning to geese. Cress-leaved rockcress (Erysium crepidifolium) and black nightshade (Solanum nigrum L.) can lead to the death of the animal if ingested.

The grass height should not exceed 15 cm; 10 cm is preferable, as grass that is too tall is trampled by the animals and is no longer eaten. Overgrown and neglected plants, as well as areas where the animals have concentrated, should be re-mowed.

Liming with approx. 10 tonnes of quicklime per hectare is recommended every two to three years. This has a disinfecting effect and binds acids in the soil. Rolling the paddock in spring levels the turf and promotes a dense grass cover. Hygiene in the area near the barn can be further improved by measures such as spreading wood chips to prevent mudding and/or the formation of puddles.

Biosecurity

A key prerequisite for a healthy, productive goose flock – alongside optimal housing conditions and the best possible provision of feed and water – is to prevent, as far as possible, the introduction of pathogens and their spread within the flock. The necessary measures to be implemented on the farm are collectively referred to as ‘biosecurity measures’. These include hygiene (cleaning and disinfection) as well as structural measures (e.g. paved forecourts and access routes, fencing, maintenance of the facilities and building fabric of sheds, hygiene sluices) and various management measures (e.g. wearing protective clothing, order and cleanliness on the farm, control of visitor traffic, pest control, handling of sick and dead animals).

Biosecurity measures must be planned on a farm-by-farm basis and implemented consistently on a daily basis to ensure a good biosecurity status. It is advisable to draw up a biosecurity plan and coordinate it with the attending veterinarian. Where there is a high risk of infection, the biosecurity plan can be supplemented by vaccinating the geese to prevent clinical disease in the flock (see Chapter 4, Vaccinations).

The farm’s operational structure also affects biosecurity status: the more contact a flock of poultry has with other animals, the greater the risk of pathogens being introduced. Farms with multiple animal species (particularly cattle and pigs) should ensure strict separation of the housing and care of different animal species. Different age groups within the goose flock should also be strictly separated from one another to minimise the risk of pathogen transmission.

Further guidance on biosecurity measures can be found in the Friedrich Löffler Institute’s factsheet “Protecting poultry”.

Biosecurity measures to prevent pathogens from entering the barn

  • Sanitisation station at the stable entrance (changing shoes, hand hygiene, protective clothing)
  • Controlled visitor access (keep stables locked; enter stables only in protective clothing worn exclusively in that stable)
  • Use of hygienically safe feed, water, bedding and enrichment materials
  • Feed storage in closed, clean containers (inaccessible to wild birds and pests)
  • Regular cleaning of equipment and vehicles used in the barn
  • No manure storage near the stable
  • Continuous rodent control
  • Monitoring of pest infestations (e.g. flies, beetles, mites) and control where necessary
  • Tidiness and cleanliness in the vicinity of the barn
  • If well water is used to water the geese: regular (annual) microbiological testing of the drinking water

 

Biosecurity measures to prevent the introduction of pathogens into the open field

It is impossible to completely protect free-range geese from exposure to pathogens. However, several bird species are often susceptible to a particular pathogen, and other animal species can also transmit pathogens to geese, albeit less frequently. Measures that prevent geese from coming into contact with other animals therefore help to improve biosecurity, even in free-range systems.

  • No open-air areas in the immediate vicinity of bird resting or breeding areas
  • Fencing of the open-air area
  • Wild bird-proof feeding (e.g. covered) and watering points
  • Regular cleaning of feeding and watering facilities (to remove any potential contamination with pathogens from wild birds or similar)
  • Entry into the animals’ living area only with protective clothing (minimum: boot covers or a change of footwear)

Even with the consistent implementation of the biosecurity measures listed, the introduction of pathogens can never be ruled out with 100% certainty. In addition to measures to prevent the introduction of pathogens, hygiene measures that prevent their proliferation and spread within the flock and its immediate surroundings are therefore extremely important for maintaining good health status in productive flocks of geese.

 

Cleaning and disinfection

Different pathogens exhibit varying levels of resistance in the environment (for example, Riemerella bacteria die off within a few days in the environment, whereas worm eggs can persist in outdoor runs for years). Organic material (animal excrement, feed residues, litter, feathers), moisture and warm ambient temperatures favour the survival of pathogens. Thorough cleaning can reduce the bacterial load on the cleaned surfaces by up to three orders of magnitude (to one thousandth of the original load). Thorough cleaning is also a prerequisite for successful disinfection, as many disinfectants react with proteins (e.g. those contained in excrement, feed residues and blood), which significantly reduces their effectiveness on heavily soiled surfaces. By combining cleaning and disinfection, the bacterial load can be reduced by up to six orders of magnitude, i.e. ideally to one millionth of the original load. However, even disinfection does not achieve a germ-free, sterile environment.

Hygiene measures during the service period

Once the geese have been moved out of the shed, it should be thoroughly cleaned before being restocked. Particularly in seasonal goose fattening, although longer periods of vacancy do help to reduce the risk of infection, cleaning should nevertheless be carried out promptly after the animals have been moved out or slaughtered to prevent the spread of any pathogens that may be present.

 

Cleaning

Cleaning begins with removing manure from the empty stable. After dry cleaning, the stable should be swept clean and then wet cleaned. In cases of heavy soiling, it is advisable to use warm water (ideally 40 °C) and cleaning agents after thoroughly soaking the soiled surfaces. High-pressure cleaners are commonly used for effective wet cleaning (Caution: unsuitable nozzles, insufficient water flow, incorrect spray angles or an insufficient spray distance can lead to material damage and the widespread distribution of dirt particles/germs!).

The amount of cleaning agents required can be significantly reduced by pre-cleaning to remove coarse dirt or by thorough soaking. Any residual cleaning agents must then be thoroughly rinsed off with clean water to prevent surface corrosion and ensure the disinfection process is not compromised.

The following must be cleaned: livestock housing (from top to bottom), livestock equipment (including feed and water lines from the inside), tools and vehicles, herding aids, loading ramps and other equipment in direct contact with the animals, livestock housing entrance areas and forecourts, feed storage containers and, finally, the equipment used for cleaning and the protective clothing worn during the process.

Cleaning is considered successful when all surfaces and interior fittings, containers, feed and water lines in the barn are clean and the waste water no longer contains any dirt particles. The wash water used contains small amounts of nitrogen- and phosphorus-containing substances and is therefore defined as liquid manure.

Disinfection

Disinfection without prior thorough cleaning is ineffective: “You cannot disinfect dirt!” However, dirt is not always visible – it is precisely invisible residues (e.g. in uneven surfaces, cracks and small openings) that severely limit the effectiveness of disinfectants and allow germs to survive until the next time the stable is occupied. Disinfection should therefore take place as soon as possible after cleaning to prevent further contamination (e.g. from dust).

The barn must be completely dry before disinfection. Wet or damp areas ‘dilute’ the disinfectant and impair its effectiveness (dilution effect).

No disinfectant kills all types of germs and is suitable for every use. In the event of disease or increased risk of infection during the fattening cycle, it is therefore advisable to discuss the details of the planned disinfection with the attending vet. As a general rule, only disinfectants tested and listed by the DVG should be used. Products bearing the DLG quality mark have also been tested for material compatibility, among other things.

DVG list

The concentration recommended by the manufacturer must be adhered to during application. It should be noted that different concentrations are required for different ambient temperatures and that certain disinfectants are ineffective or only partially effective in cold conditions (cold-induced inactivation, e.g. aldehydes). During the cold season, peroxides or chlorine solutions should therefore be used in preference. Application can be carried out using spraying, misting or aerosol methods.

As a general rule, 0.4 l of working solution per m² of surface area to be disinfected is required; for stable fittings, at least 30% extra must be allowed for. The contact time for most disinfectants should not be less than 2 to 4 hours, even if shorter times are specified by the manufacturer. Ideally, the disinfected livestock housing should then be left to air and rest ‘empty’ for 4 to 5 days.

Note

The chemicals contained in cleaning and disinfectant products can be harmful to humans and animals – particularly in concentrated form.

When handling and using these substances, it is essential to follow the safety precautions specified by the manufacturer on the label and in the safety data sheet.

Hygiene measures during the current fattening cycle

  • The hygiene airlock must be fully operational at all times.
  • Daily inspection of the supply equipment and cleaning where necessary
  • Flush the drinking system after each administration of veterinary medicines or feed supplements
  • Immediate removal of dead animals from the barn, proper storage of carcasses (see Chapter 6)
  • Bedding maintenance (checking moisture levels, adding fresh bedding and, if necessary, mucking out heavily soiled areas)
  • Clean soiled work equipment
  • Clean soiled work clothing (especially footwear)
  • Clean and disinfect equipment (including vehicles where applicable) before using them in another barn
  • Regular checks for rodent and pest infestations and control measures where necessary
  • Keep the barn entrance, forecourt and access routes clean
  • Keep vegetation in the area around the barn to a minimum

 

avian influenza

Avian influenza (highly pathogenic avian influenza, HPAI, ‘bird flu’) and the requirement to keep poultry indoors

Avian influenza is a fatal disease affecting birds. Chickens and turkeys are particularly severely affected, whilst geese and ducks exhibit milder symptoms.

The control of avian influenza is regulated by applicable EU law and, in Germany, additionally by the Avian Influenza Ordinance (GPVO). Among other things, the Ordinance stipulates that if mortality rates exceed 2% within 24 hours, or if there is a significant increase in animal losses in flocks consisting solely of geese over a period of more than four days, avian influenza must be ruled out as the cause by a vet (Section 4 GPVO).

To prevent the spread of the virus and to prevent it from entering one’s own flock, it is important to understand the routes of transmission and to take appropriate precautionary measures.

One of the most important measures is to prevent contact between farmed poultry and wild birds and their droppings. Open water bodies and feed provided in outdoor runs, for example, can attract infected wild birds. If the geese then feed and drink from the same places, they can become infected with the virus. Geese must therefore only be fed outdoors in areas that are inaccessible to wild birds, and must not be watered from surface water to which wild birds have access (Section 3 GPVO).

The pathogen, which is excreted by infected animals in their droppings as well as in secretions from the nose and eyes, can also find its way into the barn via contaminated footwear or clothing. Hygiene chambers at the barn entrances, where clothing and footwear are changed and hands are washed before entering the barn, play a significant role in reducing the risk of introduction. Vehicles that drive across the farmyard or even into the barn, such as the litter spreader, pose a high risk of introducing the pathogen. Therefore, forecourts and paths should be paved and, like the vehicles, cleaned regularly and disinfected where necessary.

Feed or the straw bedding itself can also lead to the unintended introduction of the virus into the barn if these are not stored safely away from wild birds. The GPVO therefore stipulates that feed, bedding and other items with which poultry may come into contact must be stored in a manner inaccessible to wild birds (Section 6(3) GPVO).

Straw or bedding must be stored at least under cover; ideally, it should be stored in enclosed premises. Straw that must be stored outdoors must be covered with a sturdy plastic sheet and/or a net.

In particular, the risk of HPAI introduction is higher in free-range systems compared to purely indoor housing systems, and appropriate precautionary measures must be taken. If the competent authority assesses the risk of HPAI occurrence as high, a mandatory housing order may therefore be issued (Section 13(1) GPVO).

However, if geese accustomed to grazing must be kept indoors for animal health reasons, the following animal welfare issues are to be expected:

  • Refusal to eat or drink for several days, apathy
  • Crowding together (crushing)
  • Occurrence of feather pecking and cannibalism
  • Stress-induced moulting
  • Increased susceptibility to disease
  • Increased mortality
  • Increased stress for the birds due to more frequent human contact during daily care tasks in the barn
  • Care tasks in the house (e.g. bedding).

Therefore, an exemption should be applied for from the competent veterinary authority in accordance with Section 13(3) of the Avian Influenza Ordinance. To mitigate the aforementioned problems, anyone who is able to do so should move the animals into a barn or similar facility at night so that they can become accustomed to it.

Irrespective of this, every animal keeper should have an individual ‘animal disease contingency plan’ in place, setting out the measures to be taken in the event of a compulsory housing order and how the requirements of Section 13(3) sentence 1 no. 2 of the Avian Influenza Ordinance can be met in the event of an exemption being granted. Further information on drawing up an individual animal disease contingency plan can be found in Annex 5 of the Goose Husbandry Agreement.

The housing orders issued during recent outbreaks of avian influenza repeatedly confirm the high levels of stress experienced by the animals when they are required to remain indoors. In the event of a housing order, far-reaching measures such as more frequent checks on the animals and the provision of additional enrichment materials (e.g. fresh straw or maize silage), alongside sufficient space, are therefore of the utmost importance.

Feed and water hygiene

Feed and water hygiene / Watering trough hygiene

To ensure adequate feed and water hygiene, certain principles should be observed.

  • Feed quality should be checked regularly by means of a sensory assessment of the following parameters: 
Table 4: Sensory assessment of selected feedstuffs (adapted from Kamphues et al., 2009)
Parameter Compound feed (ground grain / pellets) Cereals
Texture

dry, damp, moist

Temperature (heated), caking, webs, foreign matter, abrasion content in pelletised feed

Odour musty, mouldy, yeasty, alcoholic (yeast contamination), sweetish (mite contamination), rancid (fat spoilage), putrid/carcass-like (protein degradation) musty, mouldy, putrid, sweetish, yeasty, alcoholic, roasted aroma, stable or chemical odour, fishy (stone burn)
Taste scratchy, burnt -> indication of fat/feed spoilage unpleasantly bitter -> indication of immaturity or fungal contamination
Colour

washed-out – grey – dirty, white/yellow, green, blue discolouration

Skin surface: diffuse greying or dark discolouration (-> black mould)
Intense, clear colour typical of the grain, dirty-grey, black-brownish, red-violet (stained), green (immaturity), reddish (Fusarium contamination)
Contaminants

Insects or insect fragments, rodent droppings, other (glass splinters, ‘silo residues’),

various types of pellets (diameter, colour, structure)
Sandy-earthy impurities, seedlings, admixtures (chaff, rodent droppings, foreign bodies), storage pests such as grain weevils, mites, etc.
  • The best-before date of the feed should not be exceeded, as prolonged storage, particularly under sub-optimal conditions, can adversely affect the quality of the feed.
  • If using your own water (well water) to water the animals, regular (e.g. annual) microbiological and chemical-physical testing is recommended.
  • An important factor in providing the animals with fresh water daily is the regular flushing of the pipes and cleaning of the water troughs (particularly after the use of veterinary medicines or feed supplements via the drinking system, as well as after prolonged periods of inactivity).
  • The use of additives such as chlorine dioxide or organic acids is a suitable way of keeping drinking water pipes clean. These can, for example, be added to the drinking water via special dosing systems. The manufacturer’s instructions for use should always be followed. Physical methods such as pulse flushing (alternating air and water pulses) can also remove or prevent deposits in the pipes. However, the use of these additives does not replace regular external cleaning of the drinking facilities, e.g. round drinkers.
  • Providing an (additional) open water supply to keep the geese occupied always carries the risk of the litter becoming waterlogged and of a higher bacterial load, which can lead to an increased risk of disease in the animals. Measures should be taken to prevent this. Excess water can be drained away via (plastic) grates beneath the drinking area. It should be noted that the water must be collected and it must be possible to pump it out and, for example, spread it on arable land. Regularly moving the drinking troughs and regularly adding fresh litter around the drinking areas can also help prevent the litter from becoming waterlogged. Furthermore, the water in open drinking troughs should be changed daily.
  • Only high-quality straw (free from fungal infestation) should be used for bedding.
