【摘要】：试验通过免疫不同猪圆环病毒2型疫苗,比较3种不同疫苗对生长猪育肥阶段生产性能和经济效益的影响。试验表明:在生长育肥前期,疫苗免疫组与空白对照组在提高猪的生长性能效果上差异不显著,生长育肥中后阶段,猪圆环病毒疫苗免疫组能有效地提高猪的生长性能,降低生产成本;猪圆环病毒疫苗免疫能降低育肥猪各个生长阶段的增重变异系数,提高猪群的均匀度,且某进口基因工程疫苗的变异系数最低,重复性好;某国产灭活苗免疫组,能有效地提高猪群的经济效益。
[Abstract]:By immunizing different porcine circovirus type 2 vaccines, the effects of three different vaccines on the production performance and economic benefit of growing pigs during fattening stage were compared. The results showed that: at the early stage of growth and fattening. There was no significant difference between the vaccine immunization group and the blank control group in improving the growth performance of pigs. In the middle and later stage of growth and fattening, the porcine circovirus vaccine immunization group could effectively improve the growth performance of pigs and reduce the production cost. The immunization of porcine circovirus vaccine can reduce the coefficient of variation of weight gain and improve the uniformity of pig population at each growth stage of fattening pigs. The coefficient of variation of an imported genetically engineered vaccine is the lowest and the reproducibility is good. The domestic inactivated vaccine immunized group can effectively improve the economic benefit of pig herd.

【正文快照】： 猪圆环病毒分为?PCVl?和?PCV2血清型。其中猪圆环病毒(?PCV1)?最初研究发现在猪群中广泛传播,但是没有出现临床病例,认为对猪不具有致病性[1]。随后,1991年学者们从断奶仔猪多系统衰竭综合征(PMWS)病猪组织中分离出了在分类学和血清学上与PCV1具有显著差异的PCV病毒,命名为PCV
