Effects of Green Preparations of Probiotic-fermented Chinese Herbal Medicine on the Growth Performance,Blood Biochemical Indicators,Immune Function and Nutrient Digestibility of Meat Rabbits
摘要
Abstract
To analyze the effects of probiotics fermenting green preparations of Chinese herbal medicine on the growth,blood biochemistry,immune function and nutrient digestibility in meat rabbits,100 IRA meat rabbits were selected in this experiment,with an age of(35±2)days and an average body weight of(911.23±21.22)g.They were randomly divided into 4 groups.The control group was fed the basal diet,while the experimental groups 1,2 and 3 were respectively supplemented with 0.5％,1.0％and 1.5％green preparations of probiotic-fer-mented Chinese herbal medicine in the basal diet,respectively.The pre-feeding period was 7 days and the formal trial period was 35 days.The results showed that in terms of growth performance,the final weight and average daily gain of meat rabbits in experimental group 1,group 2 and group 3 were significantly higher than those in the control group(P＜0.05),and the feed conversion ratio was significantly lower than that in the control group(P＜0.05).There was no significant difference in the initial body weight and average daily feed intake among the groups(P＞0.05).In terms of blood biochemical indicators,the contents of serum total protein(TP),albumin(ALB)and high-density lipoprotein(HDL)in groups 1 to 3 of the experiment were significantly higher than those in the control group(P＜0.05),while the contents of urea nitrogen(UN),glucose(GLU)and total cholesterol(TC)were significantly lower than those in the control group(P＜0.05).The performance of various indicators in group 2 of the experiment was the best,and the differences were significant compared to the other two groups(P＜0.05).There were no significant differences in the contents of triglyceride(TG),low density lipoprotein(LDL),aspartate aminotransferase(AST)and alanine aminotransferase(ALT)in the three experimental groups compared with the control group(P＞0.05).The immune function indicators showed that the contents of immunoglobulin A(IgA),immunoglobulin G(IgG),interleukin-2(IL-2)and interleukin-6(IL-6)in the serum of meat rabbits in the three experimental groups were significantly increased(P＜0.05),and the content of tumor necrosis factor-α(TNF-u)was significantly decreased(P＜0.05).The contents of IgA,IgG and IL-6 in the experimental group 2 were the highest,and the content of TNF-α was the lowest.There was no significant difference in the contents of IL-2 and immunoglobulm M(IgM)between the three experimental groups and the control group(P＞0.05).In terms of the digestibility of nutrients,compared with the control group,the apparent digestibility of crude protein,crude fat and acidic washing fiber in the test group 1～3 was significantly increased(P＜0.05).Compared with the control group,test group 1 and test group 3,the apparent digestibility of dry matter and crude fiber in test group 2 was significantly increased(P＜0.05).Overall,adding a green preparation of Chinese herbal medicine fermented with probiotics to the diet of meat rabbits can significantly improve growth performance,optimize blood biochemical indicators,enhance immune function,and increase the apparent digestibility of nutrients.The best effect is achieved at an addition amount of 1.0％,and it has good promotion and application value.关键词
