摘要：

[Objective]The paper was to study the effects of fermentation bed padding on intestinal flora,serum biochemical indexes and immune function of growing-finishing pigs.[Method]A total of 90 growing-finishing pigs(Duroc X Landrace X Yorkshire)with the body weight of(30.5±0.8)kg were randomly divided into five groups,three replicates each group,six pigs each replicate.The padding of five groups were:50%rice husk+50%sawdust(control group),100%spent mushroom substrate of Pleurotus eryngii(100%spent mushroom substrate group),15%rice husk+15%sawdust+70%spent mushroom substrate(70%spent mushroom substrate group),25%rice husk+25%sawdust+50%spent mushroom substrate(50%spent mushroom substrate group),35%rice husk+35%sawdust+30%spent mushroom substrate(30%spent mushroom substrate group).The pre-trial lasted 7 d,and the formal trial lasted 90 d.[Result]Compared with the control group,the number of Escherichia col in 100%,70%and 50%spent mushroom substrate groups decreased by 35.4%,24.0%and 20.8%,respectively(P<0.05);the number of salmonella successively decreased by 29.4%,19.3%and 15.2%,respectively(P<0.05);the number of lactobacillus successively increased by 21.7%,15.9%and 12.2%,respectively(P<0.05);and the number of bifidobacteria successively increased by 20.2%,16.7%and 11.8%,respectively(P<0.05).Compared with the control group,the total serum protein content in 100%,70%,50%and 30%spent mushroom substrate groups increased by 30.6%,33.0%,28.0%and 18.4%,respectively(P<0.05);and the serum urea nitrogen content decreased by 32.4%,34.5%,33.9%and 22.0%,respectively(P<0.05).There was no significant difference in serum albumin,aspartate aminotransferase(AST)and alanine aminotransferase(ALT)between treatment groups and control group.The IgA,IgG,IgM and IL-6 levels in serum of each treatment group were significantly different from those of the control group(P<0.05).There was no significant difference in IgA,IgG,IgM and IL-6 levels among 100%,70%and 50%spent mushroom substrate groups.[Conclusion]It improves the balance of intestinal
