日粮添加益生菌改善乳鸽肠道健康和生产性能
Adding probiotics to the daily diet improved intestinal health and production performance of squabs
摘要
Abstract
[Objective]The experiment was designed to investigate the effects of adding Enterococcus faecium and Bacillus subtil-is to the daily diet on the growth performance of squabs,and whether it promoted production by regulating intestinal morpholo-gy,digestive enzyme activity,and intestinal microbial flora of squabs.[Method]A total of 240 healthy white-feathered royal pi-geons with an average age of 12 days and similar body weights were randomly divided into four groups:control group,Entero-coccus faecium group,Bacillus subtilis group,and mixed Enterococcus faecium and Bacillus subtilis group.Production perfor-mance was determined on the 16th day of the experiment(28 days of age),and slaughter samples were collected to determine the intestinal morphology of the duodenum,jejunum,and ileum,digestive enzyme activity in the duodenal contents,and the composition of the microbial flora in the colon.[Results]Compared with the control group,the Enterococcus faecium treat-ment group significantly increased the average daily weight gain from 12 to 28 days of age.Bacillus subtilis group and mixed treatment groups significantly increased duodenal amylase activity(P<0.05).Enterococcus faecium treatment group signifi-cantly increased duodenal trypsin activity.Compared with the control group,the height of the villi in the duodenum,jejunum,and ileum of squabs in the probiotic-treated groups was significantly increased(P<0.05).16S rRNA analysis of the microbial flora in the colon showed that the addition of enterococcus faecium and bacillus subtilis,alone or in combination,increased the abundance of Atopobium,Candidatus Arthromitus,and Bacillus in the colon,indicating that these probiotics had intestinal im-provement function.[Conclusion]Enterococcus faecium and Bacillus subtilis can improve the intestinal morphology of young pi-geons,increase digestive enzyme activity,increase the number of beneficial bacteria in the intestine,and promote the growth performance of squabs,showing good potential for practical application in production.关键词
