ABSTRACT
aim of this study was to evaluate the effects of the reproduct ive status of female dromedary camels ( pregnant vs. non - pregnant ) on the chemical composition, hormonal profile and antioxidant capacity of follicular fluid collected from different sized ovarian follicles during the breeding season . One hundred ovaries we re collected at slaughter house from fifty female dromedary camel s . The ovaries were collected in pairs from each animal and allocated into two groups according to the reproductive status of the females ; 25 pairs were obtained from pregnant females and 25 p airs were obtained from non - pregnant animals . The follicles on each ovary were categorized according to their diameter into three categories; small ( 1 - 3 mm), medium (4 - 9 mm) and large ( 10 - 20 mm). Follicular fluid (FF) aspirated from each follicle category from each pair of ovaries w as analyzed . The results showed that the average number of follicles per ovary was greater ( P < 0.05) in the ovaries obtained from non - pregnant females compared to those collected from pregnant ones ( 6.4 ± 1.2 vs . 3.6 ± 0.9, resp ectively). Progesterone concentrations were significantly higher in the follicular fluid collected from all follicle categories in pregnant animals than those obta ined from non - pregnant animals . Glucose concentration s were higher (P < 0.05) in the follicul ar fluid collected from large follicles in the non - pregnant group (64.9 ± 6.1 mg/d l ) than those obtained from the same follicle category in the pregnant ovaries (45.4 ± 4.0 mg/d l ). C oncentrations of malondialdehyde (MDA) were higher (P < 0.05) in the FF co llected from small, medium and large follicles in pregnant ovaries than non - pregnant ones . In conclusion , these data indicate that FF composition differ s according to the reproductive status of the female . In pregnant camels, the p resence of the corpus lut eum on the ovar ies could play an important role not only in the process of follicle growth and development , but also in the concentrations of biochemical metabolites and hormonal profiles in the FF of dromedary camels.
