Dried Whey as a Source of Unidentified Factors for the Growing Chick Four Figures

Abstract

Four experiments were carried out in which 3 to 5% dried whey was added to an all-vegetable protein (corn-soybean oil meal) diet. The feeding of this product produced an increase in the weights of the birds in all instances, even when fed with an APF concentrate containing aureomycin or with penicillin. In agreement with earlier reports, this work indicates that dried whey contains unidentified factors which are necessary for maximum chick growth.
