DIAGNOSIS OF PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME OF SWINE IN A PIG FARM OF INDUSTRIAL TYPE

. Porcine reproductive and respiratory syndrome of swine (PRRSS) is a serious threat to the pig industry in the world and Ukraine. In this article is shown the seroprevalence of PRRSS virus and is the result of the study of pathogen presence PRRSS by ELISA in terms of industrial pig farm in Dnipropetrovsk region. There are 5000 pigs, 300 of which are sows in a studied farm. Animals are typical areas for cultivation. Vaccination against PRRSS absent. When collecting history have seen next clinical signs in animals: loss of appetite, rapid exhaustion. Piglets refuse to take food. In sows are seen existing respiratory syndrome. There are abortions per 98 day of gestation, piglets are born weak. Outbreaks of disease were observed. During the performance were selected and analyzed 14 blood serum samples from domestic pigs. Samples were taken from the main herd livestock ? gilts and sows, 3 gilts and 11 sows ? once, in 8 sows ? twice in 30 days, in 6 ? three times in 4 months. This revealed the presence of antibodies to the virus PRRSS in all studied samples and thus confirmed the circulation of the pathogen in pig farm. Prospects for further development is to improve approaches to monitoring infection at involved complex serological and molecular genetic methods for the effective control of PRRSS.
