Answer Details
Natural immunity can be conferred on newly-born animals through feeding with colostrum. Colostrum is the first milk produced by the mother after giving birth, and it contains high levels of antibodies that the mother has built up over time. When the newborn animal drinks colostrum, these antibodies are passed on to them and help protect against diseases. This is important because newborn animals are born with immature immune systems and are more susceptible to infections. Vaccination and antibiotics are not natural ways of conferring immunity and do not involve the transfer of antibodies from the mother to the newborn animal. Strict sanitation practices can help reduce the risk of infection, but do not provide the same level of protection as natural immunity.
