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.
