Comparative Studies of Lipid Metabolism in Zebu and British Cattle in a Tropical Environment. I. Plasma Lipid Levels of Grazing Cattle

Abstract

Plasma lipids have been studied in 77 British (Hereford and Shorthorn), 23 rahman, 63 Brahman X British, 35 Africander, and 182 Africander X British grazing cattle. Cholesterol, phospholipid, and total lipid levels were significantly (P < 0·001) higher in Zebu breeds than in British breeds. The proportion of cholesterol present in the free state was relatively constant and given by the regression equation:
