What further increases profitability in pig production is not minimizing costs, but maximizing revenue.
These articles on porcine circovirus type 2 associated diseases present the most novel aspects, especially from the practical point of view, on etiology, pathogeny, epidemiology, diagnosis, treatment and prevention of the PCV2 infection.
Porcine circovirus (PCV2)
Despite the evident usefulness of laboratory diagnosis, we must not forget that a field necropsy allows us to us recover part of the loss caused by the death of the animal.
PCV2 vaccination of the gilts prior to insemination with PCV2 spiked-semen showed a clear decrease of viral load in the gilts as well as a much lower viral excretion that were compatible with foetus protection.
The virus is highly resistant in the environment, showing also high resistance to chemical and thermal treatments.
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.
