Effects of Clostridium butyricum on growth performance,diarrhea rate,serum immune and antioxidant indices,and fecal short-chain fatty acid concentrations in Jiaxian Red Cattle Calves
摘要
Abstract
This study aimed to investigate the effects of dietary Clostridium butyricum supplementation on the growth performance,immune function,antioxidant capacity,and fecal short-chain fatty acid(SCFA)profile of Jiaxian Red cattle calves,providing a theoretical reference for its scientific application in the healthy breeding of this breed.A total of 48 healthy Jiaxian Red cattle calves[(1-day-old,(40.56±2.23)kg,equal number of males and females]were randomly divided into 4 groups,with 3 replicates per group and 4 calves per replicate.The control group was fed a basal diet,while the diets of GroupsⅠ,Ⅱ,and Ⅲ were supplemented with 1,3,and 5 g/(head·d)of C.butyricum,respectively.The experiment lasted for 60 days.The results showed that compared with the control group,the diarrhea incidence in trial groups Ⅰ,Ⅱ,and Ⅲ was significantly reduced by 37.96%,44.75%,and 41.67%,respectively(P＜0.05).Serum IgM levels in groups Ⅰ and Ⅲ were significantly increased by 5.76%and 8.56%(P＜0.05),respectively.The IL-2 content in group Ⅱ was significantly elevated by 12.24%(P＜0.05).TNF-α concentrations in groups Ⅱ and Ⅲ were significantly decreased by 16.14%and 11.43%(P＜0.05),respectively.MDA levels in groups Ⅱ and Ⅲ were significantly lowered by 8.33%and 16.03%(P＜0.05),while T-AOC activity in group Ⅲ was significantly enhanced by 9.95%(P＜0.05).Fecal propionic acid in groups Ⅱ and Ⅲ increased significantly by 20.78%and 26.54%(P＜0.05),and fecal butyric acid rose markedly by 16.79%and 21.37%(P＜0.05),respectively.In conclusion,the addition of Clostridium butyricum to the diet enhances the immune function and antioxidant capacity of Jiaxian Red cattle calves,regulates the production of short-chain fatty acids in the intestines,and reduces the diarrhea rate.Under the experimental conditions,an addition level of 3 g per head per day demonstrated optimal efficacy.关键词
