| 摘 要： | 共轭亚油酸(CLA)因具有抗癌、抗糖尿病及增强机体免疫力等功能而备受研究人员关注,近年来,针对备受消费者青睐的羊肉和羊奶等产品中CLA含量的研究越来越多。作者简述了反刍动物产品中CLA生物合成机制,并重点回顾了多种营养调控措施对瘤胃中CLA和十八碳烯酸积累的影响结果;进一步探讨了这几种营养调控方式对羊乳和羊肉中CLA含量的影响。分析认为,利用油脂底物和调控剂混合添加有利于加强瘤胃纤维菌群和原虫区系对CLA、十八碳烯酸的积累和过瘤胃率,并可在提高动物产品中CLA含量的同时,避免乳脂率下降。今后还需通过营养、分子生物学及生理学等角度全面揭示CLA合成机理,为生产富含CLA的动物产品提供参考。

| Abstract: | Researcher pay attention to the conjugated linoleic acid (CLA) because of its function of anticancer,antidiabetic and immunological competence in the body.A lot of researches on contents of CLA in goat that enjoy high favor among people has been carried out in recent years.The article presents the biosynthsis process of CLA in ruminal,and focus on reviewing the result of many sdudies on the effects of the contents of CLA and vaccine acid in rumen;Further treat of the effects of nutrition regulation on CLA in goat's milk and mutton.Result show that the microflora and protozoa could increase the contents of CLA in rumen by using grease mixed of regulator,and increasing the contents of CLA in animal products at the same time,and avoiding to decline the contents of milk fat.we should reveal synthesis mechanism of CLA through nutrition,molecular biology,and physiology fully in the future,to provides a theoretical basis for producting CLA-enriched mutton and milk. |
