摘要
动物机体脂肪的主要生理功能是储存能源,按照分布位置可分为皮下脂肪(SF)、肌内脂肪(IMF)和内脏脂肪(VF),按照结构、来源和功能可分为白色脂肪(WAT)、棕色脂肪(BAT)和米色脂肪(BeAT)。脂肪代谢分为合成代谢和分解代谢,其影响动物的生产效率、生产成本和肉品质等。牦牛作为地方特色品种,承担着当地畜牧经济的重任,其脂肪代谢调控机制复杂。文章从牦牛脂肪分类、脂肪代谢及其影响因素和相关基因等内容,综述了年龄、品种、性别、饲养管理、营养因素以及多种脂肪代谢相关基因、非编码RNA的调控对牦牛脂肪代谢的影响,以期促进优良品种的选育,为牦牛脂肪代谢提供研究思路,也为提高养殖效益提供参考。
The main physiological function of animal body fat is to store energy,which can be divided into subcutaneous fat(SF),intramuscular fat(IMF)and visceral fat(VF)according to the distribution location,and white fat(WAT),brown fat(BAT)and beige fat(BeAT)according to the structure,source and function.Fat metabolism is divided into anabolism and catabolism,which affect the production efficiency,production cost and meat quality of animals.As a local characteristic breed,yak bears the significant responsibility of contributing to local animal husbandry economies,and its fat metabolism regulation mechanism is complex.The paper summarizes the effects of age,breed,sex,feeding management,nutrition factors,regulation of various fat metaboly-related genes and non-coding RNA on fat metabolism of yak from the content of fat classification,fat metabolism and its influencing factors and related genes,so as to promote the breeding of excellent varieties and provide a research idea for fat metabolism of yak,it provides reference for the improvement of aquaculture efficiency.
