Determination of the impacts of supplemental dietary curcumin on post-partum uterine involution using pulsed-wave doppler ultrasonography in Zaraibi goat.

This study aimed to evaluate the impacts of supplemental dietary curcumin on post-partum uterine involution using pulsed-wave Doppler ultrasonography in postpartum goats. Ten pluriparous Zaraibi goats were used and divided into two groups. Group 1 (n = 5; control) received only a base diet. Group 2 (n = 5; treated) received a base diet supplemented with curcumin (200 mg/kg diet) daily for 28 days, starting from day 1 postpartum (PP) till day 28 PP. Uterine morphometrical changes (uterine horn diameter; UHD and caruncle diameter; CD), uterine hemodynamics (resistance and pulsatility indices (RI and PI), systolic/ diastolic ratio (S/D), peak systolic velocity (PSV), end-diastolic velocity (EDV), blood flow volume (BFV), and blood flow rate (BFR)), and progesterone level were evaluated. Results revealed that the diameter of the uterine horn decreased rapidly from day 1 to day 10 PP (> 50%) but more steadily from day 14 to day 28 PP in both groups. After day 21 PP, there was nearly no reduction in UHD and CD in both groups. The treated group had lower values of the RI and PI (P < 0.05) than the control group. Regarding the BFR and BFV in the treated group, there was a significant increase (P < 0.05) on day 17 PP, then started to decrease till day 28 PP. While in the control group, there was a significant decrease (P < 0.05) in BFR and BFV from day 1 PP till day 28 PP. In conclusion, the incorporation of curcumin in the diet of PP Zaraibi goats improved reproductive performance via improvements in uterine morphometric changes as well as blood perfusion.

Follicular fluid composition in relation to follicular size in pregnant and non pregnant dromedary camels (Camelus dromedaries)

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.
