Obstetrics in cattle
Online event organised by the Hamburg Chamber of Agriculture on topics relating to birth in cattle
Most cattle births go smoothly. Nevertheless, it is necessary to constantly monitor the birth of a calf and to intervene professionally in the event of problems. This was the topic of an online event organised by the Hamburg Chamber of Agriculture on 17 February 2021 as part of the Focus on Animal Welfare network. Under the title "Obstetrics in cattle", Prof. Dr Axel Wehrend from the Clinic for Obstetrics, Gynaecology and Andrology of Large and Small Animals with Veterinary Outpatient Clinic (Justus Liebig University Giessen) spoke on various topics relating to the birth of a calf.
Influence of birth on fertility
Professor Wehrend explained to the 20 or so participants that birth is a key event that can have an impact on a cow's fertility. However, secondary diseases in calves, such as a higher death rate and poor colostrum intake, can also be the result of incorrect obstetric care. He particularly emphasised that birth monitoring is a decisive factor here. It is important that cattle farmers recognise and observe changes in the genital organs, changes in the pelvic area and changes to the udder. Nevertheless, he also expressly pointed out that "there is no reliable external, physical sign that allows birth to be predicted with an accuracy of eight hours". In order to avoid injury to the cow, premature intervention during the expulsion phase should be avoided. This can last between 30 minutes and two hours.
Practical report on the implementation of birth monitoring
Matthias Steffens, farm manager at Milchhof Steffens, then reported on his management during calf birth. Mr Steffens briefly introduced his dairy farm and talked about the dry period management of dairy cows and their feeding during the dry period. The farmer explained his practical implementation with regard to birth monitoring and possible intervention.
