It is essential for the newborn calf to receive colostrum. Colostrum is the first milk that a mother produces. Colostrum provides passive immunity to disease and helps build up vitamin and mineral levels. The new-born calf should get colostrum within the first 36 hours of birth – either from a mother or artificial sources. A supply of frozen colostrum can be kept in the freezer, while some milk replacers also contain colostrum. Once the calf has received colostrum, it can be fed solely on whole milk or milk replacers. It is handy to have a bottle of colostrum in the freezer to feed newborn calves that may not have drunk from their mothers. Warm it up to 36°C before feeding and if you have ample supply, feed it for the first two days (normally up to 2L per feed), in the morning and evening
