养猪场5种常见疫苗不同组合的免疫效果研究

Study on the Immune Effects of Different Combinations of Five Kinds of Common Vaccines in Pig Farms

[目的]优化免疫接种程序,减少疫苗接种次数以及减轻猪场疫苗接种工作量。[方法]对猪瘟、猪蓝耳病、猪伪狂犬病、猪圆环病毒病以及猪喘气病5种猪场常见猪病的疫苗按照不同组合采用混合注射、分点注射以及单苗注射等接种方式进行免疫试验。[结果]通过田间16轮次的重复试验和效果观察发现,3种不同免疫方式对猪群不同时期的抗体水平、日增重以及育成率等没有显著差异。[结论]5种疫苗不同组合混合接种在临床上具有可行性,为猪场因地制宜地制定免疫程序提供参考。

[Objective]To optimize the immunization schedule,reduce immunizing times and reduce vaccination workload in swine farms.[Method]Five kinds of common vaccines(swine fever,porcine reproductive and respiratory syndrome,porcine pseudorabies,porcine circovirus disease and mycoplasmal pneumonia of swine)in pig farms,were inoculated in different combinations by using mixed injection,point-injection and single-injection to make the immunological test.[Result]Sixteen circles of field experiments and effect observation results showed that there was no significant difference of antibody level,daily weight gain,and bred rate at different stages of swine herd among three various immunization methods.[Conclusion]The combined inoculation of different combinations of five kinds of vaccines was feasible in clinic,so as to provide reference for pig farms to make immunization procedures according to local conditions.
