There are multiple and important reasons why calves need fat in their diet. Fat is a source of essential fatty acids, which form important membrane structures in the calf, and have a key association with vitamins. Fat is also a store of energy and can be converted to sugar when the calf most needs it. Calf rearing is about keeping the calf healthy and, as importantly, developing into a ruminant so it can be weaned successfully and grow.

As we learn more about nutrition and health, the value of natural flora, the prebiotic components and the enzymes in colostrum and milk are key to calf health and development. Low-heat fresh buttermilk is a key link between colostrum and milk as it contains many of the key health components of both and helps to protect the calf’s gut and improve digestion.
