doi:10.7668/hbnxb.2011.S2.049

Abstract

Abstract: 100049,China) Fat is an important energy component in the diet of ruminants,its physiological function is mainly reflected in polyunsaturated fatty acids in nutrition.This paper will begin with a brief overview of fat in ruminant feed composition,hydrolysis of dietary lipids,hydrogenation of unsaturated fatty acids in the rumen and lipids synthesis

Key words: Ruminant, Rumen, Lipid, Hydrogenation

CLC Number:

S823
