title: Efficacy of different protocols of vaccination against porcine circovirus type 2 (PCV2) in a farm affected by postweaning multisystemic wasting syndrome (PMWS).
abstract: In order to control growing problems associated with porcine circovirus type 2 (PCV2) several vaccines for piglets or sows were introduced recently. An objective of the study was to compare an efficacy of three different vaccination protocols in the herd with acute postweaning multisystemic wasting syndrome (PMWS) outbreak affecting 3-month-old pigs. All of three applied protocols, namely vaccination of sows, piglets or sows and piglets with Circovac proved to be efficacious in controlling of PMWS. All production parameters significantly improved after vaccination. Obtained values were as good as before the outbreak or even better as in case of average daily weight gains. However, decreased mortality before weaning was recorded only after vaccination of sows while in groups where piglets were vaccinated significantly lower mortality in fourth month of life was observed. The impact of different protocols on different parameters suggests that they could be adopted in herds with different porcine circovirus associated problems.
