摘　　要：[目的]为了探索发酵啤酒糟对尼温一代奶水牛泌乳量及奶质量的影响。[方法]选择生产性能相近的健康尼温一代奶水牛27头,随机分为3组,每组9头,试验I组用5kg发酵啤酒糟(替代0.5kg精料)与精料搭配饲喂,试验Ⅱ组用5kg发酵啤酒糟(替代1kg精料)与精料搭配饲喂,对照组直接饲喂精料。[结果]表明,在120d的试验期内:①鲜啤酒糟经发酵酶解,菌体蛋白饲料的粗蛋白含量达9.1%,提高了32.65%,粗纤维含量达9.1%,下降7.14%,pH值从4.2降至4.02;②奶水牛的平均产奶量:试验I组比对照组、试验II组分别提高10.01%和7.50%,均差异显著(P<0.05),而试验II组比对照组提高2.33%,但差异不显著(P>0.05)。③发酵啤酒糟与精料合理搭配饲喂可提高水牛奶的乳脂和乳蛋白含量,并可使水牛较快进入高产奶期,而且产奶高峰后产奶量下降比较平稳[1]。[结论]发酵啤酒糟与精料合理搭配饲喂有利于提高泌乳奶水牛的产奶量及其乳脂、乳蛋白的含量。【Objective】To investigate the effects of feeding fermented brewer＇s grains on the milking performance of NIWEN milk buffalo.【Method】27 healthy cows with similar production performance were randomly assigned to 3 treatments,9 in each treatment.The treatmentⅠwas fed the basal diet with 5 kg/head/day fermented brewer＇s grains instead of 0.5 kg concentrate,and treat Ⅱ fed the basal diet with 5kg/head/day fermented brewer＇s grains instead of 1 kg concentrate.Treat Ⅲ was as the control and fed a basal diet.The experiment lasted for 120 days.【Result】The results showed that：①By enzymatic hydrolysis and fermenting,the concentration of crude protein in fresh brewer＇s grains was about 9.1%,which increased 32.65%.The concentration of crude fiber was about 9.1%,decreased by 7.14% compared with the original.The pH value decreased from 4.2 to 4.02.②Milk yield of TreatⅠincreased 10.01% and 7.50% respectively compared to the control and the Treat Ⅱ.（P0.05）.The mild yield of Treat Ⅱ was 2.33% higher than that of the control group（P0.05）.③Feeding Fermented brewer＇s grains and concentrate in proper proportions could increase the milk fat and milk protein in milk buffalo,make the milk yield reach to the peak lactation period rapidly and decline slowly after the peak lactation period.【Conclusion】Feeding Fermented brewer＇s grains and concentrate in proper proportions can increase the milk fat and milk protein in milk buffalo.
