Nutrient Digestion, Ruminal Fermentation, and Plasma Lipids in Steers Fed Combinations of Hydrogenated Fat and Lecithin1 T. C. JENKINS Department of Animal SCIence Clemson University

Clemson, SC 29634 ABSTRACT

ruminal microbes less than polyunsaturated fatty acids found in plant oils. However, saturated fatty acids are less digestible in the small intestine than unsaturated fatty acids (2, 3, 21). Hydrogenated fat containing 97% saturated fatty acids was poorly digested when fed to dairy cows in a recent study (12). Feeding lecithin increased digestibility of hydrogenated cottonseed oil in rats (2), presumably from greater emulsification of saturated fatty acids in the small intestine. In rwninants microbial phospholipasesin the rumen degra

Nutrient digestion, ruminal fermentation and plasma lipids in steers fed combinations of hydrogenated fat and lecithin.

Commercial soybean lecithin replaced hydrogenated fat in steer diets to determine if phospholipids enhance fatty acid digestion and microbial fermenta...
