Why is colostrum so important to a newborn calf?
A calf is born with a naïve immune system. The placenta of the cow does not allow immunoglobulins to pass through the maternal blood to the fetus. A newly born calf will not be able to respond to a pathogen the same way an older calf with a more mature immune system would, and is likely to become sick. Colostrum gives the calf passive immunity from its mother, and when it is about three weeks of age, it will start to develop its own immune system.
Healthy calves are the building blocks of every successful dairy and veal operation, and early management and rearing practices are a key component of raising a healthy, productive animal. Find practical ways to help your calves reach their full potential here.
The Codes of Practice are nationally developed guidelines for the care and handling of farm animals. They serve as our national understanding of animal care requirements and recommended practices.
