If you are unlucky to get infected into your herd by purchasing animals, by air or by sperm, the future of the herd must be carefully considered. There are more options:

* Stay infected and live with the disease

* Stabilize the sows/gilts/boars,  and produce negative pigs

* Sanitize the disease away

Staying infected and living with the disease is not always easy. Many studies and inventories show that PRRS costs on productivity, and not least if you have other respiratory diseases in the herd. However, the cost is a specific assessment in each case, which can only be finally settled once the PRRS infection has stabilized in the herd.

It may be possible to actively stabilize the farm by means of vaccination of sows and quarantine gilts .That way, you can achieve PRRS-free pigs. This can be a good solution, especially if you are at risk of neighboring infection.

HOW TO STABILIZE A SUBSEQUENT

We mad an experiment on 4 farms , 1 in Russia 2*7500 sows, on in Germany 1500 sows, on  in Ukraine 3000 sows, on in China 4* 4500 sows ,stabilization was based on the use of a live European PRRS (we got special permit in China and Russia )vaccine along with various management measures. The measures included rectifying pig movements, optimizing staff movement patterns around the herd, cleaning and disinfecting stables and passages, no natural cover. In addition, injection routines included the use of one needle per sow and one needle per 10 pigs.

Stabilization of the sow herds took place by herd vaccination of all sows and gills twice at one month intervals and thereafter every 16 - 20 weeks.

All piglets were vaccinated twice at intervals of one month followed by a period of vaccination of all newly weaned piglets twice by approx. one month apart. Vaccination of newly weaned piglets ceased ½ years after the first herd vaccination.

The herds were closed for new inserts of gilts / gilts for 8 weeks after the first herd vaccination, and the purchased PRRS free gilts / gilts and boars were vaccinated in quarantine twice every one month.

The success of the program was measured by the presence of virus in the blood of piglets at weaning. Later inmates and non-vaccinated gilts were also measured. The results showed that the participating herds were stabilized and weaned PRRS negative pigs, 

CLEANING FOR PRRS

If the herd is geographically reasonable in terms of the risk of neighboring contamination, remediation may be considered. The safe method is to expose all the herd animals. Of course, it is the most expensive solution.
