The study revealed that immunization of sows with a dose of commercial vaccine against PCV2 prior to insemination induces a strong humoral and consequently more homogeneous concentrations of colostral antibodies.

Currently there is only one vaccine against PCV2 specifically authorized for use in sows. This product is usually administered in two or more occasions prior to insemination or after delivery.

However, there is little information on the effect of a single dose of vaccine prior to insemination. Therefore, the aim of this study was to look for PCV2 DNA and antibodies to the virus in serum and colostrum of sows vaccinated before insemination and in piglets.

The results indicated that a single dose of vaccine prior to insemination resulted in a strong humoral and homogeneous concentrations involves a transfer of colostral antibodies against PCV2 in high and homogeneous.
