Following on from the successful format of the previous editions, Fertility and Obstetrics in the Horse 3e is a practical and user-friendly guide to equine reproduction. From explaining the anatomy of the mare's reproductive tract to detailing problems encountered during pregnancy, it covers all the major areas of concern as well as including the latest developments in diagnostic procedures and treatment techniques. * Fully updated to take into account new developments and research; * An ideal rapid reference for veterinary practitioners and veterinary students, as well as a crucial source of information and advice for those in the breeding business; * New material includes expanded sections on the stallion endometritis and embryo transfer technologies, alternative methods of fertilization and insemination techniques.
