青贮紫苏对肉牛生产性能、血液生化指标及免疫球蛋白水平的影响

通过青贮紫苏的全混合日粮对新褐肉牛的饲喂效果,比较青贮紫苏对新褐肉牛生产性能、血液生化指标、免疫球蛋白水平的影响。选择平均体重为(202.0±38.5)kg的新褐公牛40头,随机分为2组,每组20头。对照组饲喂全混合基础日粮,试验组用青贮紫苏替代全混合基础日粮中50%等量干物质的青贮玉米,试验期为60 d。结果表明:日粮中添加青贮紫苏对新褐杂交牛生长性能(干物质采食量、平均日增重和料重比)、血液生化指标(总蛋白、白蛋白、球蛋白、葡萄糖、尿素、甘油三酯、总胆固醇、碱性磷酸酶和肌酐)含量的影响不显著(P>0.05);与对照组相比,试验组血浆中免疫球蛋白A含量提高了7.62%(P<0.01),对免疫球蛋白G、免疫球蛋白M含量影响不显著(P>0.05)。

Effect of silage purple Perilla on production performance,blood biochemistry and immune globulin level of beef cattle

The effect of silage Perilla on production performance, blood biochemical index and immunoglobulin level of new brown beef cattle were compared. Forty bulls with an average weight of(202.0±38.5) kg were selected and randomly divided into two groups with 20 bulls in each group. The control group was fed with a full mixed base diet, while the test group used silage Perilla instead of silage corn containing 50% dry matter in the full mixed base diet. The test lasted for 60 days. The results showed that the addition of silage Perilla to the diet had no significant effect on the growth performance(dry matter intake, average daily weight gain and feed-weight ratio) and serum biochemical indicators(total protein, albumin, globulin, glucose, urea, triglyceride, total cholesterol, alkaline phosphatase and creatinine) of new-brown hybrid cattle(P>0.05);compared with the control group, IgA content of test group in plasma increased by 7.62%(P<0.01), and the IgG and IgM content had no significant effect(P>0.05).
