摘　　要：反刍动物的生长发育受日粮精料水平的影响。日粮精粗比和非纤维性碳水化合物/中性洗涤纤维(NFC/NDF)是反映日粮精料水平的2个常用指标。适宜的精粗比和NFC/NDF可以提高反刍动物的生产性能,维持瘤胃健康,提高经济效益。本文主要综述日粮精粗比和NFC/NDF对反刍动物生产性能、消化代谢和产品品质的影响,以期为反刍动物的日粮配制及健康生产提供参考。The growth and development of ruminant are affected by the dietary concentrate level.The dietary concentrate to forage ratio and non-fibrous carbohydrate/neutral detergent fiber(NFC/NDF)are two commonly used indicators to reflect the level of dietary concentrates.Appropriate concentrate to forage ratio can improve the performance of ruminant,maintain rumen health,and improve economic benefits.This article reviews the effects of dietary concentrate to forage ratio and NFC/NDF on ruminant production performance,digestion metabolism and product quality,in order to provide reference for the diet formulation and healthy production of ruminant.
