No differences were found in the composition of rats which had received diets of mineralized skimmed milk powder and vitamin supplements together with butter or margarine fat, corn, cottonseed, olive, peanut or soybean oils over a 12-week period. However, it was noted that male rats have a slightly higher water and protein content and a lower lipid, ash and calcium content than the females.
