The current study investigated the ovarian response to gonadotropin for establishing a suitable protocol of superovulation in Bactrian camel. Fifteen female camels were randomly divided into 4 groups to compare 4 different superovulation protocols during the natural breeding season. Each camel in 4 groups was injected with FSH at 80, 80, 60, 60, 60, 60, 40 and 40 mg, respectively total dosage of 480 mg, for consecutive 4 days at 12 h intervals. The camels in group 2-4 were naturally mated and subsequently injected 300 IU LH 48 h after the last injection of FSH, the camels in group 1 received the same procedure exception of LH injection. Ovarian follicles and corpora luteas were observed through synchronistic laparotomy 7-9 days after natural mating. The results indicated that there is no significant difference in average ovulation rate (p > 0.05) among group 1-3 nor among group 2-4. However, there is considerable difference between group 1 and 4 in average ovulation rate (p < 0.05), among which the value is highest (81.38±6.44%) for group 4 but lowest (16.89±7.98%) for group 1. Furthermore, the average number of follicles has yet no obvious difference (p > 0.05) among group 1-3 nor among group 2-4 but significant difference (p < 0.05) between group 1 and 4. Comparatively the animals in group 1 yielded highest average number of follicles (9.80±1.50). Conclusively, the protocol 4 had a best superovulatory effect with an average corpora lutea 9.33±1.45 and therefore it can be used for superovulation in camels. © Medwell Journals, 2013. Source
