Abstract

Aim of study was focus to assessment and distinguish the histological features of the camel ovary in relation to season. Materials and methods 57 ovaries were taken from adult she-camels (Camelus dromedarius) during the breeding and non- breeding seasons (37 ovaries in the breeding season and 20 ovaries in the non-breeding season). The ovaries were subjected to routine histological techniques (H&E and PAS).Result Histological findings revealed that camel ovary was covered by continuous sheet of germinal epithelium underneath a cortex which filled with different developmental stages of follicles and vascular medulla. The mature follicles had typical oocytes that surrounded with granulosa cells, cumumlus oopherus, and presence of large antrum with thick theca externa. Zona pellucida showed strong PAS positive reaction. There was difference in number of mature follicles between breeding season and non-breeding season, in which ovaries in breeding season had higher number of larger size mature follicles than during the non-breeding season. Conclusion she-camel was a seasonal breeder with marked ovarian activity during breeding season.
