Effect of vaccination of sow and piglets against porcine circovirus type 2 (PCV2) on weight gain and percentage mortality in Mexico

Abstract

The aim of this study was to evaluate the efficacy of three different vaccination protocols (sows, piglets and sows and piglets) on average daily weight gain and mortality rate in piglets from farrow to finish farm with postweaning multisystemic wasting syndrome (PMWS). During the period after vaccination (weeks 3-22) the piglets, sows and piglets, exhibited significantly improved average daily weight gain and significantly reduced mortality rate. Compared with the control group, sows and piglets vaccinated against PCV2 had a significantly higher average daily gain and significantly lower mortality rate for the study period (weeks 1-22). It is concluded that vaccination against PCV2 was effective at improving growth performance and reducing mortality rate in a herd infected with PCV2.
