Milk is the most important source of nutrition for the young calf; indeed it is indispensable. The whole digestive system is designed to digest milk.
Energy source for growth
Both colostrum as well as Sprayfo settle in the calf’s abomasum. Just a few days after birth, the abomasum already offers an acidic environment. Under the action of acid and enzymes, part of the protein in the milk becomes divided. The other part will be divided in the small intestine. These products – amino acids – are absorbed by the calf and are primarily used to promote growth.
Enzymes in saliva are able to partially break down fats, with remaining fats broken down in the small intestine. The calf absorbs these products – fatty acids and glycerol – as a source of energy. Furthermore, carbohydrates (mainly lactose) are divided into glucose and galactose in the small intestine. Absorption via the small intestine provides the calf with an additional source of energy.
