Abstract :This study was performed to determine the incidence and anatomo-pathologic aspects of reproductive organ tumors in laying chickens. For this research, 10,475 16-18-month-old, commercial laying hens of the Babcock genotype were obtained from four flocks in Afyon city. They were examined right after slaughtering, and reproductive organ tumors in 804 hens insert ignore into journalissuearticles values(7.67%); were observed. Out of these 804 hens, leiomyoma was found in 760 hens insert ignore into journalissuearticles values(7.25%);, oviduct adenocarcinoma in 39 hens insert ignore into journalissuearticles values(0.37%); and leiomyoma together with oviduct adenocarcinoma in 5 hens insert ignore into journalissuearticles values(0.05%); were detected. Oviduct adenocarcinomas were observed in the magnum of the oviduct in 43 cases insert ignore into journalissuearticles values(0.41%); and in the isthmus in one case insert ignore into journalissuearticles values(0.01%);. Leiomyomas were detected in the ventral ligament of the oviduct in 763 cases insert ignore into journalissuearticles values(7.28%); and in the magnum of the oviduct in 2 cases insert ignore into journalissuearticles values(0.02%);. In 40 cases of oviduct adenocarcinomas, metastases were observed in the intestines, pancreas, mesentery, spleen, gizzard and ovary. The macroscopic and light microscopic characteristics of these tumors were reported in detail.
