A comparison of the efficacy of sow versus individual piglet vaccination against PCV2

Home \ Research & Innovation \ Research \ Health \ A comparison of the efficacy of sow versus individual piglet vaccination against PCV2

Duration: 2008 – 2009 

Aims and objectives

  • To compare the health and performance of unvaccinated pigs to that of individually vaccinated pigs, to pigs from vaccinated mothers and to individually vaccinated pigs from vaccinated mothers in a 2 x 2 factorial experiment
  • To investigate the effect of vaccination on the virology of PCV2 

Findings to date

  • The data indicates that although there was no difference between sow vaccination treatments in the birthweight of live piglets, pigs from vaccinated sows rapidly showed improved growth rates compared to piglets from unvaccinated sows
  • These pigs were significantly heavier by one week of age and the absolute difference between the treatments increased through to weaning
  • From weaning onwards both vaccination types acted to improve pig growth rate without interaction between them
  • When the data is broken down into periods it can be seen that the effect of the sow vaccine was most pronounced during the early growth of the pig, whereas the impact of the piglet vaccine was more pronounced after seven weeks of age
  • Both vaccines are effective in improving lifetime performance and shortening time to slaughter and in this study maximum effect was gained when the two were used together
  • This resulted in six days advantage in slaughter age over the unvaccinated animal; using either vaccine singly halved this advantage.
