  Sections of camel uterus stained with immunoperoxidase for demonstration of estrogen and progesterone receptors showed that receptors for the two hormones were confined to epithelial nuclei. Staining intensity was stronger for progesterone receptors during estrus and pregnancy but weaker for estrogen receptors during pregnancy. In ovariectomized camels intramuscular administration of estradiol benzoate at a dose of 5 mg animal-1 increased uterine progesterone and estrogen receptor concentrations. Administration of progesterone at a dose of 100 mg per animal decreased steroid receptor concentrations. It is suggested that in the camel, uterine steroid receptors are up-regulated by estradiol and down-regulated by progesterone.

  It is now established practice to upgrade the protein content of low quality roughage by urea treatment. Administration of urea may result in some adverse effects. This study was carried out to investigate the effects of feeding urea-treated wheat straw diet on the hormonal and metabolic environment of ovarian follicles. Feeding of urea-treated wheat straw to camels resulted in significantly increased concentration of serum and follicular fluid urea compared to their counterparts that fed straw only. The increased urea in follicular fluid was accompanied by decreased concentration of estradiol 17 β and progesterone and increased activity of lactic dehydrogenase in the fluid. This suggested that feeding of high urea diets may affect follicular fluid composition and development of oocyte.
