Effects of Pleurotus ostreatus HXS-M1 Fermented Compound Chinese Herbal Medicine on Growth Performance,Diarrhea Condition,Serum Biochemical Indexes and Fecal Microflora of Weaned Piglets
This experiment was conducted to study the effects of Pleurotus ostreatus HXS-M1 fermented com-pound Chinese herbal medicine on growth performance,diarrhea condition,serum biochemical indexes and fe-cal microflora of weaned piglets.Seventy-two healthy weaned piglets(Duroc×Landrace×Yorkshire)with an initial body weight of(8.13±0.43)kg at 28 days of age were randomly divided into 3 groups with 4 replicates per group and 6 piglets per replicate.The control group(group C)was fed a basal diet,and the experimental groups were fed the basal diets supplemented with 0.5％unfermented compound Chinese herbal medicine(group U)and 0.5％fermented compound Chinese herbal medicine(group F),respectively.The experiment period was 28 days.The results showed as follows:1)compared with the group C,the average daily gain of group U and group F was significantly increased(P＜0.01),and the ratio of feed to gain was significantly de-creased(P＜0.01);compared with the group U,the average daily gain of group F was significantly increased(P＜0.01),and the ratio of feed to gain was significantly decreased(P＜0.01).2)Compared with the group C,the diarrhea rate and diarrhea index of group U and group F were significantly decreased(P＜0.01);com-pared with the group U,the diarrhea rate and diarrhea index of group F were significantly decreased(P＜0.01).3)Compared with the group C,the serum urea nitrogen content of group F was significantly decreased(P＜0.05),the serum total protein content of group F was significantly increased(P＜0.01),the serum total protein content of group U was significantly increased(P＜0.05),and the serum globulin content of group U and group F was significantly increased(P＜0.01);compared with the group U,the serum total protein con-tent of group F was significantly increased(P＜0.05),and the serum globulin content of was significantly in-creased(P＜0.01).4)Compared with the group C,the fecal Escherichia coli number of group U and group F was significantly decreased(P＜0.05),and the fecal lactic acid bacteria number was significantly increased(P＜0.01);compared with the group U,the fecal lactic acid bacteria number of group F was significantly in-creased(P＜0.05).In conclusion,the addition of fermented compound Chinese herbal medicine and unfer-mented compound Chinese herbal medicine in the diet can increase the growth performance and immunity,re-duce the diarrhea rate,and regulate the intestinal micro flora environment of weaned piglets.The effect of fer-mented compound Chinese herbal medicine is better than unfermented compound Chinese herbal medicine.[Chinese Journal of Animal Nutrition,2024,36(11):6958-6968]
