Abstract: [Objective] To analyze the effects of bacterial enzyme complex on immune function,serum biochemical indexes and therapeutic effect of poisoned dairy cows. [Method] Sixty poisoned cows were selected as the study subjects and divided into different groups according to the treatment methods.The included test group 1 was treated with intravenous glucose and vitamin C,and the included test group 2 was treated with oral glucose and bacterial enzyme complex,with 30 cows in each group.Meanwhile,30 healthy cows were selected as the control group.Blood routine index,serum biochemical index,serum immunoglobulin content and specific therapeutic effect were analyzed after treatment. [Result] After treatment,the indexes of white blood cells,neutrophils,red blood cells and hemoglobin in trial group 2 were all lower than those in trial group 1,and the platelets were higher than those in trial group 1,and the comparison of all indexes was statistically significant（P<0.05）,while the values of lymphocytes were not significantly changed（P>0.05）.The indexes of trial group 2 were compared with those of control group.There was no statistical significance（P>0.05）.The indexes of ALT,TBIL,ALP,CK and BUN in trial group 2 were better than those in trial group 1,and the data were statistically significant（P<0.05）,while there was no significant difference in AST between the two groups（P>0.05）.There was no significant difference between experimental group 2 and control group（P>0.05）.There was no significant difference in IgA indexes between the two groups,and the IgM and IgG levels in test group 2 were higher than those in test group 1,with statistical significance（P<0.05）.There was no significant difference in appeal indexes between test group 2 and control group（P>0.05）.The total effective rate of experiment group 2 was 93.3%,and the total effective rate of experiment group 1 was 60%,（P<0.05）. [Conclusion] For poisoned cows,treatment with oral glucose combined with microbial enzyme complexes can improve immune function and serum biochemical indicators,and enhance the therapeutic effect.
