Equine Embryo Transfer (eBook, PDF)

• Format: PDF

Produktbeschreibung

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

Inhaltsangabe

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
