摘　　要：为研究酵母培养物对绵羊生长性能和养分消化的影响。采用单因素设计,按体重完全随机地分为1个对照组、3个试验组;饲粮YC添加比例增加,ADG提高,YC添加2%时,F/G降低了8.42%,添加1%和2%的YC,NDF消化率分别增加23.06%和32.14%、ADF消化率分别提高31.3%和47.15%。添加1%~2%YC可改变瘤胃发酵模式,促进生成丙酸,降低料重比,提高绵羊增重和饲料效率。This study investigated the effects of yeast cultures(YC)on growth performance and nutrient digestion in sheep.This experiment adopted a single factor design,and the groups were randomly divided into 1 control group and 3 test groups according to body weight.The addition of yeast culture in the diet increased the ADG.When YC was added 2%,F/G decreased by 8.42%.With the addition of 1%and 2%YC,the digestibility of NDF increased by 23.06%and 32.14%,and the digestibility of ADF increased by 31.3%and 47.15%,respectively.Adding 1%~2%YC can change the rumen fermentation mode,promote the production of propionic acid,reduce the ratio of feed to weight,and improve the weight gain and feed efficiency of sheep.
