| Abstract: | The aim of this experiment was conducted to study the effects of fermented Atractylodes chinensis on serum immune and biochemical indexes of weaned piglets. Ninety-six Landrace ×Large White weaned piglets with weaning weight (6.0±0.5) kg were randomly allocated to 6 groups with 4 replicates per group and 4 weaned piglets per replicate. The weaned piglets were subjected to the following 6 treatments for 28 days:Control group was fed with the basal diet,groups Ⅰ and Ⅱ were fed with antibiotics and 0.2% unfermented Atractylodes chinensis in basal diet,while groups Ⅲ,Ⅳ and Ⅴ were supplemented 0.1%,0.2% and 0.3% fermentated Atractylodes chinensis in basal diet,respectively. The results showed that the immune and biochemical index of weaned piglets in fermented Atractylodes chinensis group had different degrees of improvement compared with control group and group Ⅰ.In the whole experimental stage,comparing with control group,the serum IgA,IgG,IgM,TP and ALB of weaned piglets in group Ⅳ were increased 10.5%,10.0%,7.8%,21.0% and 15.6%,respectively,and the difference were significant (P < 0.05),and serum ALT content was significantly reduced 20.4% (P < 0.05).Compared with group Ⅰ,the serum IgA,IgG,IgM and TP of weaned piglets in group Ⅳ were increased 7.1%,3.8%,3.8% and 12.6%, respectively,the difference were significant (P < 0.05),while the serum ALB, AST and BUN of group Ⅳ were increased 1.0%, 9.5% and 15.0%, and the difference were not significant (P > 0.05), and serum ALT content was reduced 9.4% compared with the antibiotics group (P > 0.05). |
