172. The effect of commercial sterilization on the nutritive value of milk. IIb. A note on the effect of the method of feeding dried skimmed milk on the biological value of its proteins

Abstract

1. In experiments in which the biological value of the proteins was measured spray dried skimmed milk was fed separately from or mixed with a basal “nitrogen free” diet. 2. At a 6·9% level of protein (N x 6·38) intake the first method of feeding yielded a biological value of 87·2, the second of 90·3. The difference was not statistically significant (odds of 9: 1 against chance factors). 3. The findings do not account for the low biological value reported by us previously for the proteins of raw liquid milk.
