摘　　要：皮下脂肪是能量代谢和内分泌系统的重要组成部分,对畜禽的生长和肉质起着重要作用。皮下脂肪组织在动物体内具有隔热、能量储存和脂肪因子分泌等多种功能。皮下脂肪厚度以及肌内脂肪含量与肉类产量和质量密切相关,脂肪沉积会浪费大量能量,并且影响胴体的瘦肉百分比,因此降低皮下脂肪含量对畜禽生产非常重要。本文就影响皮下脂肪沉积的关键转录因子、非编码RNA、关键代谢酶及其调控机制进行综述,为了解动物皮下脂肪沉积的机制,改进肉类产品的产量和质量,更有效地控制动物的脂肪含量和脂肪分布提供了参考依据。Subcutaneous fat is an important component of the energy metabolism and endocrine system,and plays an important role in the growth and meat quality of livestock and poultry.Subcutaneous adipose tissue has a variety of functions,including thermal insulation,energy storage and secretion of adipokines.Subcutaneous fat thickness and intramuscular fat content is closely related to meat yield and quality.Reducing subcutaneous fat content is very important for livestock and poultry production because fat deposition wastes a lot of energy and subcutaneous fat affects the percentage of lean in the carcass.In this paper,key transcription factors,non-coding RNAs,key metabolic enzymes and their regulatory mechanisms affecting subcutaneous fat deposition are reviewed to provide a reference basis for understanding the mechanism of subcutaneous fat deposition in animals,improving the yield and quality of meat products,and controlling the fat content and fat distribution of animals more effectively.
