Abstract

The influence of supplementation of diets with some lipid sources (i.e., whole cottonseeds, flaked whole soybean seeds, and calcium soaps) on the composition of milk fat from dairy cows, bred in 50 farms of the Brescia province, was evaluated; 117 bulk milk samples were collected, and the lipid fraction was analyzed. Considerable variations in the composition of both fatty acids and triglycerides were detected, and these variations showed a good correlation with the amount of crude lipids in diets. The application of ratios between fatty acids as an index for butterfat purity is ineffective due to the modifications of the fatty acid composition.
