That can work for a specialized single-commodity hog farm. In the case of a multiple-commodity farm, that is to say one with two or more types of production, as in the case you referred to a little earlier, or in the case of a farm that only has family labour, it won't work.
What can we do on the farm to eradicate circovirus? A year ago in Quebec, a committee of veterinarians and representatives of the ministry of agriculture, fisheries and food was formed to gain a better understanding and to better manage this disease, even across Canada.
As I mentioned a little earlier, a pilot vaccine was developed last spring with the approval of the Canadian Food Inspection Agency, to vaccinate the herds. There has been a decline in the incidence of the disease. Furthermore, our internal governance, that is to say our way of working in our buildings, has changed. Currently, the disease that affected the first herds is subsiding, and everything's falling back into place. Since the disease did not hit all the herds at the same time — it broke out in some in 2004 — it's taken time for the veterinarians to really realize what caused the outbreak of the disease. We had to wait one year for procedures to be taken and put in place. Some things have been corrected, but it's taken nearly a year to achieve good results. The vaccine has achieved one part of the progress, and work methods the other. It's gradual because not everybody was affected at the same time. The vaccines aren't available for everyone. Even if a number of producers request the vaccine, some have to wait since veterinarians only have a limited number of doses.
