For this reason, a total of 48 female Japanese quails (Coturnix coturnix Japonica) aged 14 weeks were used as a material. While red hot pepper (Capsicum annuum L.) seeds were added to the diet of the animals in the experimental group at the rate of 2%, 4%, and 6%, it was not added to the control group. At the end of the study, while the number of white follicles showed a statistically significant increase in all groups compared to the control group (P<0.05), a significant increase was recorded in the number of yellowish follicles in the groups in which 2% and 4% red pepper seeds were added to the diet compared to the control group. Also, the correlation analysis revealed that there was a positive correlation between the yellowish follicle and the white follicle. In the present study, it was observed that there was a negative correlation between magnum length and isthmus length (r=-0.369, P=0.019), while there was a positive correlation between the total length of the oviduct and yellow follicle diameter (r=0.335, P=0.034). Consequently, it was concluded that the addition of red-hot pepper (2% and 4%) seeds to the diet may increase egg yield in quails.eninfo:eu-repo/semantics/openAccessBiyolojiFizyolojiSağlık Bilimleri ve HizmetleriZoolojiArticle122202610.53913/aduveterinary.13251121213812
