【摘要】：为了研究日粮中添加不同剂量地衣芽孢杆菌对断奶五指山猪生产性能、血清生化指标和免疫指标的影响,试验将72头体重(10.47±1.12)kg的健康五指山猪随机分为4组,1组为对照组,饲喂基础日粮;试验1,2,3组日粮中分别添加100,200,400 g/t地衣芽孢杆菌制剂,试验期为40 d,测定五指山猪的生产性能、血清生化指标和免疫指标。结果表明:试验3组猪平均日增重显著高于对照组(P0.05),料重比显著低于对照组(P0.05);试验末重和平均日采食量各组间差异不显著(P0.05);试验3组猪血清白蛋白含量和碱性磷酸酶、谷丙转氨酶和谷草转氨酶活性显著高于对照组(P0.05);试验1,2,3组猪尿素氮水平和对照组相比虽有所降低,但差异不显著(P0.05);试验2,3组血清Ig M含量显著高于对照组;各组间猪Ig A和Ig G含量差异不显著(P0.05)。说明断奶五指山猪日粮中地衣芽孢杆菌的适宜添加量为400 g/t。
[Abstract]:In order to study the effects of different doses of Bacillus licheniformis on production performance, serum biochemical index and immune index of weaned Wuzhishan pigs, 72 healthy Wuzhishan pigs with weight of 10.47 卤1.12 kg were randomly divided into 4 groups as control group. 100,200,400 g / t Bacillus licheniformis preparation was added to the diets of trial 1 / 2 group, and the production performance of Wuzhishan pigs was measured for 40 days. The results showed that the average daily gain (ADG) of the three experimental groups was significantly higher than that of the control group (P0.05N), the ratio of feed to weight was significantly lower than that of the control group (P0.05N), the difference of the end weight of the test and the average daily intake was not significant (P0.05N), and the difference between the three groups was not significant (P 0.05). The content of porcine serum albumin and alkaline phosphatase, The activity of alanine aminotransferase and alanine aminotransferase was significantly higher than that of control group (P0.05), the level of urea nitrogen in group 1 was lower than that in control group, but the difference was not significant (P 0.05), the content of serum IgM in group 2 was significantly higher than that in control group. There was no significant difference in the contents of IgA and IgG among the three groups, indicating that the suitable addition of Bacillus licheniformis in diet of weaned Wuzhishan pigs was 400 g / t.
