Effect of months on levels of serum estradiol and progesterone hormones in the one- humped camel (Camelus dromedaries)‎

Abstract EN

This study was conducted at the Animal Farm, College of Veterinary Medicine, University of Anbar during the period from September, 2012 to January, 2013.

This experiment included 12 multiparous, non-lactating Iraqi one-humped female camels (Camelus dromedarius) of 7-8 years old.

Blood sample were collected and Radioimmunoassay (RIA) used to measure the plasma estradiol-17β (pg/ml) and plasma progesterone concentration (ng/ ml).

Higher level (P<0.05) plasma estradiol-17β in October (35.75 ± 2.019) and the lower during December, September and November (31.83 ± 3.094, 31.33 ± 2.533 and 31.17 ± 2.160) respectively.

Plasma Progesterone concentration were significantly (P<0.05) higher during December (1.309 ± 0.514), than September, October and November (0.724 ± 0.080, 0.641 ± 0.090 and 0.608 ± 0.116).

It was concluded that there is a clear effect of months on levels of serum estradiol and progesterone in the one- humped camel
