Abstract:

This study was conducted to determine the effects of dietary Bacillus coagulans supplementation on plasma antioxidant indexes and intestinal mucosal growth of piglets.Thirty healthy weaned piglets (21-day-old) were randomly divided into three experimental groups (10 replicates per group):Control group,group Ⅰ and group Ⅱ.The control group was fed the basal diet,and the experimental groups Ⅰ and Ⅱ were fed the basal diet+2.0×106 and 2.0×107 CFU/g of Bacillus coagulans,respectively.On day 21 of the trail,blood samples were collected and then all the piglets were sacrificed and intestinal mucosa were collected for analysis.The results showed that:Compared with control group,the plasma superoxide dismutase (SOD) activity,the ratio of villus height to crypt depth in jejunum and ileum,the ileal TP content and the ratios of RNA to DNA of pigs in both groups Ⅰand Ⅱ were significantly increased (P<0.05); The plasma malondialdehyde (MDA) content of pigs in group Ⅱ was significantly decreased (P<0.05), while the TP content and the ratio of TP to DNA in jejunum of pigs in group Ⅰ increased significantly (P<0.05).In conclusion,under the conditions of this experiment,dietary supplementation with Bacillus coagulans could enhance the antioxidant capacity of weaned piglets,promote the proliferation and renewal of intestinal mucosal cells,and improve the intestinal mucosal morphology.

Key words: Bacillus coagulans; weaned piglets; plasma antioxidant indexes; intestinal mucosal morphology; intestinal mucosal growth
