Colostrum is a wonderful source of Igs, vitamins and nutrients for the newborn calf. However, as great as colostrum is, it still can not overcome the effects of a calf being born in a dirty environment. Calves which are born in a manure-covered closeup pen or which nurse a filthy teat when they first stand up will be overpowered by bacteria inspite of colostral absorption. All equipment used to feed colostrum to newborn calves should be kept very clean. Supplements There are no supplements for colostrum which are more conveniently located or in ample, low cost supply than the colostrum which the dam produces for her calf.
Commercial supplements are less effective.
