Abstract

Abstract: Residual feed intake (RFI) is an important evaluation index for feed efficiency of livestock and poultry. miRNAs are a class of endogenous non-coding single-strand RNA molecules with length of around 22 nt, which are important regulators for gene expression. Previous studies revealed that miRNAs were closely related to feed intake and energy metabolism of animals, which participated in the regulation of RFI in cattle, pigs, chickens and other animals. This article summarized the research status of RFI, especially the research progress of miRNA regulating RFI of livestock and poultry in recent years, which would help to reveal the molecular regulation mechanism of RFI trait, provide new ideas for the improvement of feed efficiency and efficient production of livestock and poultry, and provide a theoretical basis for molecular breeding of the high-quality livestock and poultry.

Key words: livestock and poultry, feed efficiency, residual feed intake, miRNA

摘要： 剩余采食量（residual feed intake, RFI）是评价畜禽饲料利用率的重要指标。microRNA（miRNA）是一类通过转录后抑制基因表达的内源性非编码单链RNAs，长度约为22 nt，是基因表达的重要调控因子。miRNA与动物机体的采食及能量代谢密切相关，参与调控牛、猪、鸡等动物的RFI。针对近年来畜禽RFI的研究现状，特别是miRNA调控畜禽剩余采食量的研究进展进行总结，有助于揭示畜禽RFI性状的分子调控机理，为畜禽饲料利用率的改良与高效生产提供新思路，为优质畜禽的分子选育工作提供理论依据。
