Abstract

The objective of the current study was to investigate the ultrasonographic characteristics and hormonal profile of| mares affected with hemorrhagic anovulatory follicles (HAFs) in late follicular phase (3 days prior to the expected time of ovulation) to predict the development of the case. For this reason, normal cyclic Straight Egyptian Arabian mares (n=9) and those suffering from repeated hemorrhagic anovulatory follicle formation after 2 successive cycles (n=15) were investigated. Ultrasonographic Ovarian examination was done using real time B-mode scanners. Ovarian examination and collection of blood samples were done daily during the late follicular phase till the occurrence of hemorrhage in affected mares and ovulation in control normal cyclic ones. Depending on the ultrasonographic examination, blood samples were selected at 3 days prior to expect time of ovulation (day-3) and: on day of expected ovulation (day 0). The assaying hormones were Anti-Miullerian hormone (AMH), estradiol 17-β, progesterone and cortisol. Ultrasonographic characteristics did not show changes between the HAF and normal cyclic mares. Meanwhile, hormonal profile revealed significant decrease in the concentration of AMH in HAF group Vs normal cyclic ones in day-3 and day 0. Unlike to this manner, estradiol concentration showed significant increase in HAF mares in the two periods of the study. Progesterone concentration recorded si significant increase only in HAF affected mares on day 0 of study. Whereas, the cortisol concentration did not reveal any significant changes all over time of investigation. In conclusion, Ultrasonographic characteristics helped in the diagnosis of AHFs in mares rather than prediction. Whereas, lower concentrations of AMH could be served as predictor for the development of HAF in mares helping in appropriate management for this affection
