摘要:

为研究日粮中添加不同剂量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,选健康、体重接近(7.58 kg±0.23 kg)的"杜×长×大"三元杂交仔猪96头,随机分为4个处理组,每个处理组3个重复,每重复8头猪,其中处理1组为对照组,不添加枯草芽孢杆菌;其他3个处理组分别为试验Ⅰ、Ⅱ、Ⅲ组,分别在基础日粮中添加0.1%、0.2%、0.4%的枯草芽孢杆菌制剂。试验期为40 d。结果显示,试验Ⅱ组的末重、平均日增重和平均日采食量均显著高于对照组(P< 0.05),但料重比差异不显著(P> 0.05);日粮中添加枯草芽孢杆菌对断奶仔猪血清总蛋白、白蛋白、碱性磷酸酶、谷丙转氨酶和谷草转氨酶的影响均差异不显著(P> 0.05),而试验Ⅰ、Ⅱ组试验猪血清尿素氮含量显著低于对照组(P< 0.05);日粮中添加枯草芽孢杆菌对断奶仔猪血清IgA、IgM和IgG含量的影响均差异不显著(P> 0.05);日粮中添加0.2%枯草芽孢杆菌显著提高断奶仔猪血清超氧化物歧化酶活性(P< 0.05)。结果表明,在海南气候条件下,以试验Ⅱ组效果最好,建议生产中断奶仔猪日粮中枯草芽孢杆菌添加量为0.2%。

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(groups Ⅰ,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 group Ⅰ and group Ⅱ were 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%.
