Effect of aerobic exercise on microbial abundance in small intestine of Tan sheep in fattening period
The experiment aimed to explore the impact of aerobic exercise on the abundance and function of intestinal microbiota in the small intestine of Tan sheep in fattening period.Sixty female Tan sheep lambs with a weaning weight of(16±2)kg were selected and randomly divided into three groups,with 20 lambs in each group.Tan sheep in the group 1 exercised daily for 8～10 km,Tan sheep in the group 2 exercised daily for 4～6 km,and the Tan sheep in the control group were in the barn.The experiment lasted for 130 days.The results showed that compared to the control group,the number of operational taxonomic units(OTUs)in the duodenum,jejunum,and ileum of Tan sheep in the group 1 increased.Compared to the control group,the relative abundance of Proteobacteria in the duodenum and Actinobacteria in the jejunum of Tan sheep in the group 1 significantly increased(P<0.05),and the relative abundance of Actinobacteria in the ileum of Tan sheep in the group 2 significantly increased(P<0.05).Compared to the control group,the relative abundance of Ruminococcus in the duodenum of Tan sheep in the group 2 significantly decreased(P<0.05),and the abundance of Solobacterium in the duodenum of Tan sheep in the group 1 and group 2 decreased extremely(P<0.01).Compared to the control group,the relative abundance of Bacteroides,Clostridium,and Escherichia-Shigella in the jejunum and ileum of Tan sheep in the group 1 significantly decreased(P<0.05),and the relative abundance of Bacteroides in the jejunum of Tan sheep in the group 2 extremely decreased(P<0.01).The study suggests that daily aerobic exercise of 8～10 km during the fattening period can enhance the diversity of intestinal microbiota in Tan sheep,increase the abundance of beneficial bacteria,reduce the abundance of harmful bacteria,and improve the overall health of the small intestine.
