To give calves the best possible start in life, an optimal supply of colostrum is of paramount importance. As calves are born without their own immune system and only develop one during the first week of life, passive immunisation through the cow’s first milk after calving – known as colostrum or first milk – is essential. Colostrum contains immunoglobulins that protect the calf from pathogens until it has developed its own immune system. However, it can only be fully effective if the colostrum is administered as quickly as possible and in sufficient quantities. But what exactly does ‘as quickly as possible’ mean? And how much is sufficient? And, of course: what should I do if the calf cannot suckle independently?

The Working Group on Feeding Systems in Calf Rearing, part of the Fokus Tierwohl network, has examined all these questions in depth. The findings were summarised in collaboration with veterinarian Dr Theresa Scheu from Hofgut Neumühle.
