摘要
对妊娠期母猪进行猪瘟疫苗免疫,观察其抗体变化情况;采用5种商品猪瘟疫苗免疫仔猪,检测其在一免和二免情况下的抗体变化规律。结果表明:仔猪猪瘟母源抗体与母猪的抗体水平正相关,妊娠母猪在妊娠期60-80 d免疫无显著差异,不同来源疫苗的免疫效果相似,二次免疫效果优于一次免疫。
To survey and evaluate the vaccine potency, pregnancy sows were vaccinated with Classical Swine Fever Vaccine, and piglets were vaccinated once or twice with five kinds of Vaccines against Swine Fever. The results showed that there were positive correlation between the maternal antibody of piglets and the antibody of sows. Antibody titers showed no significant difference in pregnancy 60d, 70d and 80d, no matter which brand product. Comparing the immune effect two shots were better than one shot.
