Evaluation of a long-acting recombinant bovine FSH for multiple ovulation and embryo transfer in dromedary camels.

The present study was conducted to test a new super-agonist recombinant bovine FSH (rbFSH) to induce superovulation (SOV) in dromedary camels. In experiment I, a single IM injection of 40, 60, 80, 100, or 120 µg rbFSH was administered (4 donors per group) to determine the effective dose resulting in acceptable multiple ovulation and embryo yield. Administration of 40 µg was ineffective, while 100 and 120 µg were associated with increased numbers of developed follicles, corpora lutea, and recovered embryos compared to administration of 60 and 80 µg.
