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 (7.67%) were observed. Out of these 804 hens, leiomyoma was found in 760 hens (7.25%), oviduct adenocarcinoma in 39 hens (0.37%) and leiomyoma together with oviduct adenocarcinoma in 5 hens (0.05%) were detected. Oviduct adenocarcinomas were observed in the magnum of the oviduct in 43 cases (0.41%) and in the isthmus in one case (0.01%). Leiomyomas were detected in the ventral ligament of the oviduct in 763 cases (7.28%) and in the magnum of the oviduct in 2 cases (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.trinfo:eu-repo/semantics/openAccessLaying henReproductive organTumorAnimaliaAvesGallus gallusArticle0001743394000042-s2.0-170444427122733261Veterinary sciencesCockatoos; Amazona; Ara AraraunaFemaleAnimal modelArticleAvian stomachCancer incidenceChickenControlled studyHenGenotypeLeiomyomaIntestineMesenteryMicroscopyMetastasisNonhumanOvaryOviductPancreasSpleenUterine tube carcinoma
