摘要

本试验旨在研究饲粮中添加发酵酒糟对舍饲牦牛生产性能、养分表观消化率、瘤胃发酵和血清生化指标的影响。选取20只(208.30±3.31) kg年龄为3周岁的麦洼公牦牛,采用完全随机试验设计,将牦牛随机分为2组(A和B组),每组10个重复,每个重复1头牦牛。A组饲喂玉米-豆粕型饲粮,B组饲粮中添加9.25%的发酵酒糟,设计成与A组等氮的玉米-发酵酒糟型饲粮。试验期60 d。结果表明:与A组相比,1)B组的干物质采食量和日增重显著提高(P0.05);4)B组显著提高了血清总蛋白和高密度脂蛋白的含量(P0.05)。由此可见,饲粮中添加9.25%的发酵酒糟可提高牦牛的生产性能和对营养物质的消化率,但不改变瘤胃发酵类型,且对血清生化指标无不良影响。

Abstract

The objective of this study was to determine the effects of fermented distillers' grains supplemented in diets on performance, apparent nutrient digestibility, ruminal fermentation and serum biochemical indices in house-fed yaks. A complete randomized design was adopted in this study, and twenty 3-year-old Maiwa male yaks weighted (208.30±3.31) kg were randomly divided into 2 (A and B) groups with 10 replicates of 1 yak in each group. Yaks in A group were fed corn-soybean diet, and yaks in B group were fed the corn-fermented distillers' grains diet which contain 9.25% fermented distillers' grains and equal nitrogen content compared with the diet of A group. The experiment lasted for 60 d. The results showed as follows: compared with A group, 1) dry matter intake and daily gain in B group were significantly increased (P0.05); 4) serum total protein and high-density lipoprotein contents in group B were significantly increased (P0.05). Consequently, the diet that contain 9.25% fermented distillers' grains can improve performance and nutrients digestibility in yaks, but does not change the type of rumen fermentation, and has no adverse effects on serum biochemical indices.
