摘　　要：剩余采食量效应(RFI)是评估肉牛饲料转化效率的一个新指标。本文从RFI的定义、影响RFI的生理基础、RFI与甲烷排放量的关系、RFI的经济效益、RFI的遗传力与遗传相关及RFI分子标记研究进展等方面对肉牛净进食效应的相关研究进行了综述。Residual feed intake （ RFI） is a new measurement to assess feed conversation ratio of beef cattle. The article introduced briefly researches related to net feed intake of beef cattle from the following aspects：the definition of RFI, the physical basics affecting RFI, the relationships between RFI and methane emission, eco-nomic implications of RFI, hereditary capacity and genetic correlation of RFI and research advances on the rel-ative molecular markers of RFI.

关 键 词：剩余采食量效应 饲料转化效率 肉牛
