Milk replacers for the neonatal calf.

A rather long list of broad generalizations exist regarding milk replacers for calves. At least two more general statements should be added to that list. Most broad generalizations regarding milk replacers should be applied cautiously; and if young calves (less than 2 to 3 weeks) are to be fed milk substitutes, the products should be of high quality. Our primary goal in feeding baby calves should be health oriented--that is, not to pre-dispose to or cause diarrhea through diet. This means using milk-source ingredients in milk substitutes targeted for young calves. The preponderance of data presented in this article underscores that statement. Milk replacers containing nonmilk sources of major nutrients are better fed to older calves.
