PCV2 Vaccines Reduce Time to Slaughter
UK - PCV2 vaccines improve the lifetime performance of pigs and shorten time to slaughter, according to preliminary results from a BPEX trial.
Full results and analysis of the trial, carried out at the Pig Development Centre’s Leeds University site, Spen Farm, are expected by the end of the month.

The project investigated the effects of sow vaccine Circovac and piglet vaccine Circoflex. It compared the piglet or sow vaccine only, the piglet and sow vaccines combined and an unvaccinated control.
Initial results indicate that the combined vaccine programme reduced time to slaughter by six days. Using only the sow or piglet vaccine in isolation resulted in a reduction of three days.
The sow vaccine appears to reduce piglet mortality in the first 24 hours resulting in heavier litters at weaning, while the piglet vaccine improved growth rates after seven weeks of age.
The work complements field trial results, reported in April, from BPEX's vaccine voucher scheme.
