Superovulatory Responses and Embryo Recoveries in Rathi (Bos indicus) Cattle with Different Doses of Folltropin-V
Abstract: <div>The superovulatory responses and embryo recoveries in Rathi cows superovulated with different doses of Folltropin-V were tested. Post-partum cows were superovulated 60 days post-partum using 400, 300, 200 or 240 mg of Folltropin-V administered in 8 descending doses 12 h IM starting from day 8-10 of a CIDR-B. Cows were induced to estrus by IM administration of a prostaglandin (Inj Cyclix) and withdrawal of CIDR-B at the time of last</div><div>injection of FSH. Cows were inseminated thrice at 12 h interval using frozen semen. Embryos were recovered by non-surgical means on day seven of insemination. Transrectal ultrasonography was performed on the day of embryo recovery to record the number of unovulated follicles and the number of corpora lutea. Estrus expression was poor in superovulated donors which posed a difficulty in precise timing of insemination.</div>
