The virus is highly resistant in the environment, showing also high resistance to chemical and thermal treatments.
Porcine circovirus (PCV2)
Might be there is a little doubt nowadays on the beneficial clinical and economic effects of PCV2 vaccination in subclinical infections in piglets, but… which is the role that sows play in the whole picture?
This economic model was create to provide a decision support tool for farmers and veterinarians, who can enter their own data to calculate the severity of PMWS on their farm, the cost of disease and what could be the most cost-effective control measure.
PCV2 may reach embryos/foetuses upon transplacental spread during viremia or upon insemination with contaminated semen.
It has been shown that the efficacy of PCV2 vaccines was dramatically decreased in the context of husbandry deviations such as excess of cross-fostering, mingling at weaning or very large groups in nursery.
The efficacy of PCV2 vaccines to control PCV2 associated diseases has been clearly demonstrated not only in piglets but also in sows. Moreover, it is also feasible to vaccinate sows and their offspring without hampering its growth during the rearing period.
Experimental Mhyo and PCV2 co-inoculations have resulted in somewhat divergent results.
