A cow’s gestation period is around nine months. The newborn calf will take his or her first drink from their mother, as the first feed contains colostrum, which is full of nutrients and antibodies. However, once the newborn calf has drunk the colostrum, the farmer separates them from their mother, normally within the first 24 hours. This is done so that the farmer can take as much milk as possible to be sold for human consumption.
