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60d。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(P<0.05),料重比则显著降低(P<0.05);2)B组的总能、有机物、中性洗涤纤维和酸性洗涤纤维的表观消化率显著提高(P<0.05),而粗蛋白质的表观消化率无显著变化(P=0.471);3)B组显著提高了瘤胃液氨态氮、总挥发性脂肪酸、乙酸和丙酸含量及纤维素酶活性(P<0.05),但乙酸/丙酸无显著变化(P>0.05);4)B组显著提高了血清总蛋白和高密度脂蛋白的含量(P<0.05),且有提高球蛋白含量的趋势(P=0.097),而血清谷丙转氨酶、谷草转氨酶活性和白蛋白、尿素氮、胆固醇、甘油三酯和低密度脂蛋白含量无显著变化(P>0.05)。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。

摘  要：
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 1yak 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(P<0.05),and feed/gain were significantly decreased(P<0.05);2)the apparent digestibility of gross energy,organic matter,acid detergent fiber and neutral detergent fiber in B group were significantly increased(P<0.05),but no significantly change was found in that of crude protein(P=0.471);3)the contents of ammina nitrogen,total volatile fatty acid,acetate and propionate,and total cellulase activity in rumen fluid in B group were significantly increased(P<0.05),but no significant difference was found in rumen fluid acetate/propionate(P>0.05);4)serum total protein and high-density lipoprotein contents in group B were significantly increased(P<0.05),and there was a trend that serum globulin content in B group was increased(P=0.097),but no significant difference was found in serum alanine transarninase and alanine transarninase activities,and albumin,urinary nitrogen,cholesterin,cholesterin and low-density lipoprotein contents(P>0.05).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.
