What is colostrum? Colostrum is the first milk produced by all mammals.
It contains many antibodies produced from the mum that help with immunity of the newborn animals.
Lambs, calves, kids and crias are born with no natural immunity so rely on this to help protect them from the bacteria and bugs that they are picked up from the environment.
In the past, the term 'colostrum' has been used to describe the first four days of milk, however we now commonly refer to the colostrum as different types — gold colostrum and then transition milk.
Gold colostrum is the first milk immediately after giving birth and then transition milk is the milk that follows over the next four days.
