The natural immunity to diseases in calves is acquired through access to colostrum. Colostrum is the first milk produced by a cow after giving birth to a calf. It contains high levels of antibodies and other immune-boosting compounds that help protect the calf from infections and diseases during the first few weeks of life. Calves that do not receive colostrum are at a high risk of contracting infections and diseases, as their immune system is not fully developed yet. Therefore, it is essential to ensure that calves receive colostrum from their mothers within the first few hours of birth.
