摘要
为评估圆环疫苗免疫对猪生长性能的影响,选取2 598头14日龄仔猪分为3组,分别免疫1头份猪圆环病毒2型(porcine circovirus 2,PCV2)疫苗、0. 5头份PCV2疫苗和生理盐水,通过对比仔猪生长性能指标对疫苗免疫效果进行评价。结果表明,疫苗剂量对断奶仔猪平均日增重和死亡率的影响差异不显著(P>0. 05),70日龄时1头份疫苗免疫组平均日增重显著高于生理盐水处理组。
To evaluate porcine circovirus 2(PCV2)vaccine on performance of nursery pigs,2 598 pigs were selected and randomly divided into 3 groups.Piglets in group A,group B,group C were injected 1 dose PCV2 vaccine,0.5 dose PCV2 vaccine,normal saline,respectively.Average daily weight gain(ADG),mortality and feed conversion rate(FCR)were detected.The results showed that PCV2 vaccine dose had no significant difference on ADG and mortality of piglets(P>0.05),but 1 dose PCV2 vaccine could significant increase ADG of piglets compared to control group.
