PMWS has hit the Quebec swine industry hard since 2004. Dr. Camille Moore did a study of the mortality of growing pigs for the first 8 months of 2005 in comparison to 2004. After he completed this study he created a large list of intervention strategies that producers can follow to attempt to control PMWS, in which most of them failed. In order to attempt to control this disease, Drs. MC Germain and Alain Ricard studied vaccinations. Circovac from France is to be given to sows before farrowing and partially depends on colostrums intake of the piglets. Circovac has resulted in variable reduction in mortality in the grow/finish period, but has shown a general improvement. Vaccines against PCV2 are now available as well.
