Abstract
To examine the effect of prostaglandin F2α on induction of parturition in pregnant she camels, 500 µg of prostaglandin F2α (Estrumate; Coopers, England) was injected intramuscularly in to five pregnant she camels, at 380-383days of gestation. Parturition occurred in all of them 23 to 31 hours post-injection. Mean plasma concentrations of progesterone significantly (p<0.01) decreased from 1.97 ng/ml on day injection to 0.35 ng/ml on day of parturition. Also a significant (p< 0.01) increase in the mean concentration of Estradiol-17β (88.25 pg/ml compared to 35.5 pg/ml) was noted. The results suggested that prostaglandin F2α has direct effect on corpus luteum leading to rapid parturition.
