复合益生菌培养物对育肥牛血液生化指标及免疫功能的影响

Effects of Compound Probiotic Culture on Blood Biochemical Indexes and Immune Function of Fattening Cattle

摘要:

通过在日粮中添加复合益生菌培养物，探讨育肥牛血液生化指标及免疫功能的影响。选用体重约210kg体重接近的西门塔尔牛（约1岁）40头，随机分为4组，研究日粮中复合益生菌培养物添加水平对肥育牛血液生化指标及免疫功能的影响。结果显示所有试验组均不同程度提高育肥牛血清白蛋白(ALB)、总蛋白(TP)、总胆固醇(CHO)、葡萄糖(GLU)、甘油三酯（TG）、谷草转氨酶(AST)、谷丙转氨酶(ALT)、碱性磷酸酶(ALP)等各项血液指标和血清IgG、IgA、IgM、IL-4、IL-6、和IFN-γ的含量，说明饲粮中添加复合益生菌培养物对育肥牛血液生化指标及免疫功能的提高效果明显。其中从试验数据来看，试验2组（基础日粮+20‰复合益生菌培养物）综合效果表现相对最佳。

Abstract:

In this paper, by adding compound probiotic cultures to the diet, the effects of blood biochemical indexes and immune function of fattening cattle were discussed. We selected 40 Simmental cattle (about 1 year old) with a body weight of about 210 kg and randomly divided them into 4 groups to study the effects of dietary compound probiotic culture on blood biochemical indexes and immune function of fattening cattle. The results showed that serum albumin (ALB), total protein (TP), total cholesterol (CHO), glucose (GLU), triglyceride (TG), aspartate aminotransferase (AST) Transaminase (ALT), alkaline phosphatase (ALP) and other blood indicators and serum IgG, IgA, IgM, IL-4, IL-6, and IFN-γ levels. This shows that the addition of compound probiotic cultures in the diet has a significant effect on improving the blood biochemical indicators and immune function of fattening cattle. From the experimental data, the comprehensive effect of the experimental group 2 (basic diet + 20‰ compound probiotic culture) was relatively the best.
