Abstract:

Superovulation, embryo recovery and transfer were attempted in twenty 8-10 years old Iranian dromedary camels which had at least one calving. Superovulation was done using two commercially available porcine FSH preparations, FSH-a (12 donors) and FSH-b (8 donors) during a luteal phase created by inducing ovulation with human chorionic gonadotrophin (hCG). The superovulatory response was assessed by ultrasonography. The embryo recovery was     attempted non-surgically in sitting position on day 7 and 6 after first mating in the FSH-a and FSH-b groups, respectively. Considerable individual variation in response to superovulation was observed. No significant difference was observed between the two groups in terms of superovulatory response and embryo recovery (P>0.05). In total, 30 embryos were recovered from 18 donors (1.66 embryos/donor). Recipients were synchronized with donors using hCG. Eight embryos were transferred, resulting in three pregnancies and two live births.
