This book briefly reviews the history of equine embryo transfer, covering in clinically practical terms the techniques, equipment, and management protocols currently in use. Embryo transfer has become a big business, especially for breeding racing stock (horses and camels), and is therefore a very important aspect of equine practice. Ed Squires and Pat McCue have been involved with the development of embryo collection and transfer procedures since the early 60s and have both contributed important techniques and innovations to the process through their research and clinical experience. This book captures the clinical experience, so far, and applies it directly to equine practice. The book is of great value to general equine practitioners for reference, equine reproduction specialists, animal science at the graduate level (equine track), and breeders.

Contents 1. Introduction General Introduction (i.e. what is ET) Advantages and uses of embryo transfer Changes in the ET Industry Breed regulations (include a Table of most major breeds; ET, frozen embryos, etc.) Per cycle ET Success = Embryo Collection Rate (50-60%) x Embryo Transfer Pregnancy Rate (70-80%)Goals of the Manual 2. History of equine embryo transfer Livestock Horses Domestic horses as surrogates for endangered equids(?) 3. Reproductive Anatomy and Physiology of the MareAnatomy of the mare Physiology of the estrous cycle Physiology of early embryonic development and early pregnancy 4. Management of the donor mare Selection of the donor Evaluation of the donor (BSE)Management and Day of breeding (fresh, cooled, frozen semen) Palpation/ultrasound examinations relative to flush; daily vs every 6-8 hrs for frozen semen; BID if goal is to collect a small embryo at day 6.5 for cryopreservation Induction of ovulation (hCG and deslorelin) Donor mare management (PMIE, fluid, etc.)Estrous cycle control (Lights, P&E, PGF, hCG, Deslorelin, Regumate) Allow a mare to carry to term by approximately 10 years of age Allowing mare to carry own every 3-4 years Effect of repeated flushing on uterine health and embryo recovery # flushes per year recommendedFertility of mares after flushing (i.e. same season)Problem mares (i.e. PMIE, etc.) Maiden mares (young vs older)Post partum mares (i.e. flushing on foal heat) 5. SuperovulationHistoryTechniques EFSH Optimal follicle size at onset Problems - same stallion vs. goal of different stallions Not every mare responds to FSHPAF's and HAF's 6. Embryo Collection Equipment (Box Table) Facilities (stocks vs stall, etc.) Procedure; (incl. clean out and wash up) Ultrasound prior to flush in problem
