چکیده
The objective of the present study was to evaluate the efficacy of a porcine circovirus type ۲ (PCV۲) double vaccination in weaning piglets reared for gilts under field conditions. The study was conducted at a Greek farrow-to-finish conventional pig farm with a previous history of PCV۲ infections. The trial included ۹۶ female piglets at ۲۱ days of age, which were equally allocated to two different study groups. Piglets of the group-۱ received a single PCV۲ vaccination at ۲۱ days of age, while piglets of the group-۲ were double vaccinated against PCV۲, at ۲۱ and ۴۲ days of age. The results indicated that the piglets of group-۲ had better growth performance, as they showed higher body weight (BW) and average daily weight gain (ADWG). In addition, ELISA tests showed that the double- vaccinated piglets presented a better humoral response against PCV۲, as higher levels of IgG antibodies were detected in them than the piglets of the group-۱. In conclusion, the current results suggested that a double PCV۲ vaccination of piglets, reared for gilts, on a PCV۲-affected farm could lead to higher protection against the virus.کلیدواژه ها
