The purpose of this study was to compare efficacy of LCE (load-close-expose) using attenuated PRRSV to that using live-virus exposure on breeding herds acutely infected with PRRSv.

PCV-2 and PRRS are the most common infectious causes of abortions. Most abortions are also found to occur during the colder months, regardless of their cause.

The reasons behind the vaccination against influenza virus on a group of fattenig units with recurrent respiratory clinical pictures that belong to an integrated production system are discussed. Impact on production parameters and economic results are also shown.

The farmer, alarmed, calls us describing a clinical picture of abortions in the last third of gestation, weak newborn piglets, stillbirths, mummified piglets, agalactia, sows with fever and small litters.

The economic potential lost in a unit positive to PRRS could be around 35 – 37% of net unit margin.

We are talking about PRRSV, M. hyo, PCV2, App and swine influenza virus.

Needle-free injection technology improves the dispersion of vaccines throughout the tissue.

Without the participation in the program of all farms present in the area, progress will be minimal or nil.

NFID administered swine vaccines can use half to a tenth of the dose required for intramuscular vaccines because of the higher antigen dispersion and contact with the antigen presenting cells found in skin.

A method to quantify the relative economic importance of pig health status at placement by specific pathogens (PRRSv and PEDv) and to estimate the effect of a specific type of PRRSv at a specific production system is presented.

The method is based on oral fluid collection from the groups of viraemic pigs by means of cotton ropes that will be hung in the incoming gilts pens.

The first and the most important condition at the beginning of PRRSV control program is to disrupt virus circulation in the reproductive herd.

Effect of modified-live porcine reproductive and respiratory syndrome virus vaccine on the shedding of wild-type virus from an infected population of growing pigs.

After 24 years of experience we still don't have a control plan agreed upon and accepted by all our technical community. Why?

The accuracy and security provided by the combination of samples of weaned pigs and piglets at birth, either stillborn or live piglets, help us make a decision that will be crucial in any eradication plan.

Only a few EU countries are discussing national eradication as a possibility.
