Porcine parvovirus (PPV) is one of the causative agents in reproductive disorders in swine that causes great economic losses. The objective of our research was to determine prevalence of this infection on farms with intensive breeding in 5 municipalities in Vojvodina. The research encompassed 19 herds with a total of 344 blood samples screened for the presence of antibodies against PPV (gilts, breeding sows and boars). Serological examination was carried out by haemagglutination inhibition test (HI test). After the analyses of the results, seropositive animals were detected on the farms and there were no PPV-free farms. The determined antibody titre against PPV ranged from 1:64 to 1:16384. Out of 344 examined animals, there were 305 (88.66%) with a high antibody titre (1:1024 to 1:16384). The highest level of antibodies (1:16384) was detected in 145 animals, what is 42.15% of total number. In 24 animals (6.97%) titre antibody was 1:512 and these animals were of low seropositivity. Simultaneously, a comparison of antibodies in blood sera was carried out on 20 gilts (Table 3, farm 2) originating from a farm where the animals were vaccinated against PPV and 20 unvaccinated gilts (Table 4, farm 1) originating from a farm without vaccination against PPV. In unvaccinated animals antibody titre was unequal and ranged from 1:256 to 1:16384, in unvaccinated animals the values were considerably higher and ranged from 1:4096 do 1:16384, and in 17 out of 20 vaccinated pigs (85%) the highest antibody titre was 1:16384.
