枯草芽孢杆菌对断奶仔猪生长性能和血清生化指标的影响
Effect of Bacillus subtilis on Growth Performance and Serum Biochemical Parameters of Weaned Piglets
摘要
Abstract
The experiment was conducted to investigate the effects of the Bacillus subtilis on growth performances and serum biochemical parameters of weaned piglets.A total of 96 pigs(Duroc×Landrace×Yorkshire) were randomly allocated to four treatments, each treatment had three replicates of 8 pigs.The pigs in control group were only fed basal diet, and those in other groups(groupsⅠ,Ⅱ and Ⅲ) were fed basal diet supplemented with 0.1%, 0.2% and 0.4% Bacillus subtilis, respectively.The experiment lasted for 40 d.The results showed that the average end body weight, average daily gain and average daily feed intake in group Ⅱ were significantly higher than that of control group (P<0.05), and the F/G in group Ⅱ had no significant difference with that of control group (P>0.05).The contents of ALB and TP had no significant differences in all groups, the activities of ALP, ALT and AST in serum had no significant difference in all groups too, and the contents of BUN in serum of groupⅠand group Ⅱwere significantly lower than that of the control group (P<0.05).The contents of IgA, IgM and IgG in serum of all groups had no significant differences (P>0.05).The content of serum superoxide dismutase was significantly higher with add 0.2% Bacillus subtilis to the diet of weaned piglets (P<0.05).It was concluded that the growth performance and serum biochemical parameters of group Ⅱ was best in weaned piglets, and suggested that optimal dietary Bacillus subtilis level was 0.2%.关键词
