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?

Resolving the basis of viral and host variation will require identification and characterization of key B- and T-cell epitopes conserved among diverse PRRSV, and of the molecular and structural details of key effector antibodies, T-cell antigen receptors, and MHC molecules that mediate broad, cross-protective immunity.

Although a commensal, M. hyorhinis may cause serious systemic disease through mechanisms that are not fully understood.

The most effective way of avoiding the production losses associated with the PCV2 consists in avoiding the appearance of the viraemia by inducing a passive or an active immunity that minimizes the circulation of the virus in the farm.

In 1996, the NFMDTF drafted a national plan to address the 1995 FMD epidemic wherein 98,000 animals were reported to have been affected.

The FMD Eradication Project in the Philippines has formally ended but activities have been sustained even after obtaining FMD-freedom in Luzon having no clinical cases for 5 years with the last outbreak recorded in December 28, 2005.

One issue is to overcome maternal immunity, which is true for all PCV2 vaccines in the market, and another is whether the most from these vaccines is achieved independently of the PCV2 antibody titre at vaccination

In the first part of management of the breeding chart we basically looked at how it can help us to control returns. In this second part we will look at other applications.

We may have some highly efficient vaccines, but we shouldn’t forget that for their application we must obtain good diagnostic information, and that in all cases we should not lose sight of good management and a good control of the concomitant diseases.

Between 1995 and 1997, at the beginning of an epizootic called “maladie de l’amagrissement du porcelet” (MAP), it was observed that the farms that were most affected and that had the most losses, generally presented obvious deviations from what we would consider to be a suitable management of the animals and facilities. This is why Dr. François Madec made a list of management practices with the aim of improving the anomalous situation observed.

The use of diagnostics will allow producers and practitioners to work together towards the common goal of PRRS eradication

The presence of subpopulations of exposed and non-exposed sows in chronically PRRSV-infected breeding herds assists in the maintenance of virus circulation in the breeding herd over time.
