| 摘 要： | 为研究饲料中添加抗菌肽粗提取物对断奶仔猪生长性能及蓝耳病毒抗体水平的影响,本试验选取120头断奶二元仔猪,随机分为4组,每组2个重复,每个重复15头。对照组饲喂基础日粮,试验1组、2组、3组分别在基础日粮中添加0.1%、0.2%、0.4%抗菌肽粗提取物,试验期为30d。结果表明:与对照组相比,试验2组、3组末重分别提高6.9%、8.8%(P<0.05),日增重分别提高10.4%、12.4%(P<0.05),料重比分别降低6.4%、5.7%(P<0.05),蓝耳抗体效价分别提高46.5%、72%(P<0.05),阳性率各组之间差异不显著(P>0.05);试验2组、3组甘油三酯较对照组分别提高10.9%、13.4%(P<0.05),试验1组、2组、3组胆固醇含量较对照组均显著降低(P<0.05),试验2组IgG含量较对照组提高12.6%(P<0.05),试验2组、3组IgA含量较对照组分别提高35.6%、51.1%(P<0.05)。综述,日粮中添加抗菌肽粗提取物可提高断奶仔猪血清中蓝耳抗体水平,提高免疫功能,改善生长性能。
