摘　　要：饲料利用率性状是畜禽的重要经济性状之一,直接影响畜禽的养殖成本和经济效益。畜禽饲料利用率性状的遗传基础复杂多样,涉及多基因表达、网络调控和信号转导等方面。长链非编码RNA(long non-coding RNA,lncRNA)是一类长度超过200个核苷酸的RNA分子,其在基因表达调控中扮演着重要角色,与动物的采食、能量代谢、肌肉发育和脂质代谢等过程密切相关,对畜禽的饲料利用率性状具有重要的调控作用。文章对近年来畜禽饲料利用率性状的研究进展进行总结,有助于揭示畜禽饲料利用率性状的分子调控机制,为畜禽饲料利用率的改良与生产效益的提高提供新角度,也为优质畜禽的分子选育工作提供理论基础。Feed efficiency is one of the key economic traits in livestock and poultry,directly affecting breeding costs and economic benefits.The genetic basis of feed efficiency traits in livestock and poultry is complex and diverse,involving multi-gene expression,network regulation,and signal transduction.Long non-coding RNAs(lncRNAs),which are RNA molecules longer than 200 nucleotides,play important roles in the regulation of gene expression.They are closely related to the processes such as feed intake,energy metabolism,muscle development,and lipid metabolism,and have a significant regulatory effection on feed efficiency traits in livestock and poultry.This paper summarized recent research progress on feed efficiency traits in livestock and poultry,aiming to elucidate the molecular regulatory mechanisms of these traits,which would provide new perspectives for the improvement of feed efficiency and economic benefits in livestock and poultry production,and offer a theoretical basis for the molecular breeding of high-quality livestock and poultry.
