Natural immunity against diseases is conferred on the newly born animal through feeding with colostrum. Colostrum is the first milk produced by female mammals immediately after giving birth. It contains high levels of antibodies, which are proteins that fight against diseases and infections. When a newborn animal drinks colostrum, the antibodies in the colostrum are absorbed into its bloodstream, providing it with natural immunity against a wide range of diseases. This immunity is temporary and gradually fades away over time, but it is crucial in protecting the animal during its early life. Vaccination, sanitation, and administration of antibiotics and drugs can also help to protect animals against diseases, but they do not confer natural immunity like colostrum does.
