    Differences in the Follicular Morphology of Young and Aged Bitches and Their Correlation with the Anti-Mullerian Hormone
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2016) Korkmaz, Omer; Korkmaz, Deniz; Polat, Ibrahim Mert; Yagci, Ilknur Pir; Pekcan, Mert; Emre, Birten; Zonturlu, Abuzer Kafar
    This study aimed to investigate the structural, morphological and cellular differences of follicles at different stages of follicular development as well as to determine the correlation of the ovarian follicle population with serum Anti-Mullerian Hormone (AMH) levels in young and aged bithches. Sixteen bitches were divided into two groups according to their ages. Group A included young bitches aged 2 years (n=8) while Group B constituted of those aged 8 to 10 years (n=8). Diameters of the primordial, primary and preantral follicles were found to be significantly larger in Group B, in comparison to Group A. In Group A, the mean number of granulosa cells was 91.65 +/- 2.23 in the secondary follicles and 301.31 +/- 4.16 in the preantral follicles. In Group B, the same values were found to be 89.46 +/- 2.68 and 270.25 +/- 3.54, respectively. The mean serum AMH levels in Group A and Group B were 0.233 +/- 0.046 ng/mL and 0.099 +/- 0.008 ng/mL, respectively (P<0.05). In conclusion, the results indicated that the number of primordial and primary follicles as well as the numbers of granulosa cells in secondary and preantral follicles decreased with advanced age which resulted in lower serum AMH levels in aged bitches. The results suggested that the AMH, which is used as a fertility parameter in humans, could also be used for the same purpose in dogs.

    The Effects of Hot Pepper Seeds Added to the Diet in Quails on the Morphology of the Oviduct and Ovary
    (2023) Korkmaz, Deniz; Kırar, Nurcan; Top, Şermin; Yıldırım, Özge; Aydın, Sadık Serkan; Korkmaz, Ömer; Çetin, Mehmet
    The aim of this study is to reveal how red-hot pepper seeds added to the diet in quails change ovarian follicle dynamics and the morphological structure of the oviduct. 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.
