A comparison between steroidal hormones in follicular fluids and histological change of the dominant and cystic follicles of local breeding cows.

[摘要] The cystic ovarian follicle are a serious cause of reproductive failure in cattle because they occur frequently and prolong the intervals from postpartum to first estrus and conception. The paired ovaries were collected from forty four slaughtered cow after examination by rectal palpation to diagnosis of the cystic follicle stricter, the local breeding cow were primarily AlGenobea , Al-Kradea and Al- Shrabea cow , the age of its cow are (4-6) years but the reproductive status were unknown.The cysts follicle fluids contain high significantly of oestradiol and progesterone ( p <0·05) than the dominant follicle fluids.The histological characteristics of the dominant follicles (17-25 mm) are shown Small antral and have a granulosa cell layer and internal theca cell layer, but the cystic follicles which presented the large granulose cell layer, which was basically a poly-layer .Aim of this studies are comparison of the estradiole (E2) & progesterone (P4) concentrations in the follicular fluids of the dominant follicles and cystic follicles ,with studies of the histological change between the follicular walls.
