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.
为了控制与猪圆环病毒 2 型（PCV2）相关的日益严重的问题，最近已经推出了几种仔猪或母猪疫苗。本研究的目的是比较在暴发急性断奶后多系统消耗综合征（PMWS）的猪群中三种不同疫苗接种方案的效果，受影响的猪为 3 月龄。应用的三种方案（即母猪、仔猪或母猪和仔猪接种 Circovac）都证明在控制 PMWS 方面是有效的。接种后，所有生产参数均显著改善。获得的值与暴发前一样好，甚至比平均日增重更好。然而，仅在母猪接种后断奶前的死亡率降低，而在仔猪接种的组中，第四个月的死亡率明显降低。不同方案对不同参数的影响表明，它们可以在具有不同猪圆环病毒相关问题的畜群中采用。
