不同圆环病毒2型疫苗对生长育肥猪影响的研究

Effects of Different Porcine Circovirus Type 2（PCV2） Vaccines on Pigs during Growth and Finishing Stage

摘要:

为评估不同圆环病毒2型疫苗对生猪生长肥育期免疫效果，本试验选择国产和进口两种疫苗，对同一批23日龄断奶长大二元杂交去势仔猪360头，随机分成A、B、C三组，每组120头，A组免疫国产SEPPIC佐剂PCV2a全病毒灭活疫苗（WH株）、B组免疫进口水质佐剂亚单位疫苗（PCV2a Cap蛋白），C组不做任何处理。结果显示，与国产圆环病毒2型疫苗相比，进口疫苗在生长性能、抗体水平及免疫保护期等方面均表现出了较强的优势，经济效益较为显著。

Abstract:

In order to evaluate the immune effects of different porcine circovirus type 2（PCV2） vaccines on pigs during growth and finishing stage, a total of 360 piglets weaned and 23 days of age were randomly divided into groups A, B and C with 120 pigs in each group. Group A was immunized with domestic PCV2a whole virus inactivated vaccine (WH strain) with SEPPIC adjuvant, group B was immunized with imported water adjuvant subunit vaccine (PCV2a Cap protein), and group C was not treated with any treatment. The results showed that compared with the domestic PCV2 vaccine, the imported vaccine showed strong advantages in terms of growth performance, antibody levels and immune protection period, etc., with significant economic benefits.
