Studies on the Comparative Nutritive Value of Fats

Abstract

No differences were found in the fertility of male or female rats which from 21 days of age had received diets of mineralized skimmed milk powder fortified with the necessary fat-soluble vitamins and various fats irrespective of whether the lipid was butter, a margarine, corn, cottonseed, olive, peanut, or soybean oil. Moreover, such diets were equally efficient in promoting lactation as judged by the weights of the rats when weaned at 14 or 21 days of age.
