Abstract: Reoviruses are ubiquitous in chickens and turkeys; some strains become viremic and localize in the large joints, resulting in arthritis, tendinitis, and synovitis. Avian Reovirus Vaccine is a Killed Virus for the subcutaneous or intramuscular revaccination of healthy chickens 10 weeks of age as an aid in the prevention of signs and lesions associated with avian reovirus infections which cause malabsorption syndrome. The aim of present study was to clinical evaluation the efficacy of Tri-Reo vaccine in broiler breeders by ELISA method. In this study which carried out during the 2012, we worked on the poultries of 2 farms with 6 halls in each, in that, salon No. 6 considered as control group. Others were considered as experimental group with different titrs of vaccine. In these farms, the first Tri-Reo vaccination applied on week 7 and the second time was on week 19. In fact, the Tri-Reo vaccine was administrated two times during the study. At the end, blood samples were obtained from chickens for laboratory procedures. The data showed that the titr obtained on day 1 was lesser than titr obtained after second vaccination in both farms (p<0.05). In conclusion, it shows the necessity of further investigations in other parts of our country as well as other flocks such as layers, layer breeders and broilers. The investigations should consider different aspects of the disease to identify risk factors which may be responsible for pathogenicity of the virus.
