摘要
绵羊脂肪可广泛应用于人类日常生活中,如饮食、化妆品、工业原料等。因此了解绵羊脂肪沉积的分子机制至关重要。由于绵羊生长到一定阶段后会加剧皮下脂肪和内脏脂肪的沉积,导致其饲料转化率下降,为避免经济效益低廉的皮下脂肪和内脏脂肪的沉积,增加提升绵羊养殖产业生产价值的肌内脂肪的沉积,该文分析品种、性别、营养水平、不同部位对绵羊脂肪沉积调控机制的影响作用,对于在绵羊脂肪沉积中发挥关键调控作用的非编码RNA及KEGG信号通路的研究进展进行阐述,以期为解析绵羊脂肪沉积的遗传机制提供理论依据。
Sheep fat can be widely used in human daily life,such as diet,cosmetics,industrial raw materials,etc.Therefore,it is important to understand the molecular mechanism of fat deposition in sheep.As sheep will aggravate the deposition of subcutaneous fat and visceral fat after growing to a certain stage,leading to the decline of feed conversion rate,in order to avoid the deposition of subcutaneous fat and visceral fat with low economic benefits and increase the deposition of intramuscular fat that can enhance the production value of sheep breeding industry,this paper analyzes the effects of variety,gender,nutrition level and different parts on the regulation mechanism of sheep fat deposition,At the same time,the research progress of non coding RNA and KEGG signal pathway that play a key role in regulating fat deposition in sheep was described,so as to provide theoretical basis for analyzing the genetic mechanism of fat deposition in sheep.
