Cross-sectional sampling (different age groups during one herd visit) has the advantage that results are obtained quickly.

In this second part the actions described are the ones needed when the disease is already in the country.

In the last 4 batches of weaned piglets, the farmer saw around 3% of anorexic and lethargic piglets. All the treatments he tried failed (amoxicillin or florfenicol injections), and finally the piglets died.

ASF spreads mainly through the movement of infected pork and other animal products, as well as live animals, which includes wild boar.

Monitoring protocols in boar studs are often insufficient to timely detect an infection.

Four virus lineages, having clearly distinguishable HA, are currently co-circulating in European pigs and can be considered as enzootic viruses, even if their relative prevalence and level of incidence vary from one country to another.

After the clinical and serological evaluation it is decided to vaccinate against PRRSV, with which we achieve a gradual improvement in the health status on the farm. Some months later, a severe cough appears in the fattening pigs that later also appears in the nursery and in the sows.

The first cause of PCV vaccine failure is the purchase and use of generic vaccine of low quality and titre, but the exact cause of the failures can occur in various forms.

ASF is now firmly established in some areas of the Caucasus and Eastern Europe, where it is causing considerable trade disruptions, plus having a devastating impact on small-scale pig farmers.

Pigs in a commercial environment are consistently exposed to (sub) clinical infections and stressors, and systemic responses to such challenges significantly reduce the growth potential of modern pigs.

The veterinarian is called from a new established herd in Brittany because some clinical signs appear on gilts from the two first deliveries introduced in the farm.

During 2012 PCV2 variants or mutants (mPCV2) appeared in the USA and were frequently associated with PCV-associated diseases. The possibility of lack of cross-protection of commercial vaccines against mPCV2 is now of major concern.

The first goal of the project is to control PRRSv-infections in order to produce negative offspring.

The interaction between M. hyopneumoniae and its host make M. hyopneumoniae one of the most important contributors to porcine respiratory disease.

Reducing piglets mingling in farrowing and nursery facilities was found to delay the infectious process leading to a lower number of early infections. Clustering piglets by litter in small units after weaning also decreased significantly the probability of early infection.

Frequent deaths and cases of disease with typical “diamond-skin” lesions appeared in fattening pigs although they were vaccinated against Erysipelothrix rhusiopathiae.
