摘要
反刍动物产品如牛奶,牛、羊肉等,是人类重要的膳食组成,其脂肪品质及脂肪酸组成与人体健康密切相关,如何合理调控反刍动物脂肪代谢过程,优化饲养模式,改善产品脂肪品质是反刍动物脂类营养研究的关键问题。作者对2007～2008年反刍动物脂类营养研究进展作一简要综述。国内的研究热点主要集中于脂肪酸代谢通路的研究、补充脂肪(脂肪酸)对反刍动物生产性能及产品脂肪酸组成的影响和瘤胃惰性脂肪的应用研究。而国外反刍动物营养脂类研究中除了上述3点外还对乳腺脂肪酸代谢调控和瘤胃后脂肪酸消化、吸收方面有较深入的研究。
Ruminant products is one of the main sources of human diet, the fatty acid composition in it is closely related to human health. Research efforts have focused on nutritional management practices in lipids digestion and metabolism to improve production efficiency and the quality of the ruminant products. In the past two years, considerable progress has been made in increasing the understanding of lipid digestion and metabolism in ruminant. In this paper we have referred 126 articles related to ruminant lipid nutrition via PubMed, CNKI and the ADSA-ASAS annual joint meeting abstracts （2007 to 2008 editions） to make a review of the research progress of ruminant lipids nutrition in 2007 to 2008. The research program consist of kinetics of fatty acid metabolism in digestion tract, regulation of fatty acids metabolism in mammary gland, the effect of fat （fatty acids） supplement diet on ruminant production and fatty acid composition in fat. Effect of rumen rennet fat on production in ruminants and the cooperation effects of fat with other diet additives.
