摘要: 日粮脂肪(酸)是反刍动物重要的营养素之一,与反刍动物生产性能、动物脂肪产品品质及脂肪酸组成密切相关,如何调控反刍动物脂肪代谢过程,改善脂肪产品品质是反刍动物脂类营养研究的热点。作者对2010年反刍动物脂类营养研究进展进行了综述。研究领域主要集中于脂肪酸瘤胃代谢调控、瘤胃后供给脂肪酸代谢及需要量、日粮脂肪(酸)对反刍动物生产性能和繁殖性能及产品脂肪组成的调控作用和过瘤胃保护脂肪的应用研究。

关键词: 脂肪(酸)营养; 反刍动物; 代谢; 调控

Abstract: Lipid in diet is one of the main sources of ruminant,it is closely related to ruminant production performance,and also associated with quality and fatty acid composition of ruminant products. Recent researches have focused on measurement practices in lipids digestion and metabolism to improve efficiency and quality of ruminant products. In this review,The author had reviewed the advance in ruminant lipids nutrition in 2010. The current research progress is consist of regulation of fatty acid metabolism in rumen,the efficiency of postruminal infusion of fatty acid metabolism and requirment content,the effect of fat (fatty acids) supplement diet on ruminant production and reproduction performance and fatty acid composition of ruminant products,as well as effect of rumen protected fat on production in ruminants.

Key words: lipid nutrition; ruminant; metabolism; regulation
