摘要
剩余采食量(RFI)是动物饲料效率的一种表述方法,变异机制与多种因素有关。本文回顾并总结了近年来不同RFI反刍动物的生产性能、行为特征、体组成、营养物质分配、能量利用、瘤胃发酵与消化和基因表达相关的表型特征及机制研究,并基于多组学研究探究在反刍动物中RFI变异的生理机制,筛选其潜在的生物标志物。
Residual feed intake(RFI)is widely accepted as the standard for evaluating feed efficiency in ruminants,and its variation is determined by various factors.This review paper presents a comprehensive analysis of recent studies on the phenotypic characteristics and underlying mechanisms associated with RFI in ruminants,including performance,behavioral traits,body composition,nutrient partitioning,energy utilization,rumen fermentation,digestion,and gene expression.The physiological mechanisms responsible for the variation in RFI among ruminants and identify potential biomarkers were explored with multi-omics approaches.
