Abstract
Blood and milk lipids from cows with butterfat depression were sampled and analyzed. The triglycerides of milk fat were normal in fatty-acid composition, while the the free fatty acids in milk showed a high proportion of short chain fatty-acids indicating that the problem does not result from an acetate shortage. Blood lipids were significantly altered in composition. Many unknown peaks (10) comprising up to 40% by weight of the fatty-acids in certain lipid fractions were evident by gas chromatography. Overall the blood lipids were deficient in the level of stearic acid, a normal blood component in the ruminant.This publication has 15 references indexed in Scilit:
