    A concise and liberally illustrated working guide on Broodmare health and breeding management for veterinarians, veterinary students and breeders. The presentation includes all of the clinical procedures and assessments necessary for maintaining the health and breeding soundness of the Broodmare. This handy reference covers the use of ultrasonography for diagnosis and monitoring of the mare, cytologic studies essential to diagnosis, normal and abnormal reproductive anatomy, culturing techniques for infections, diseases affecting the reproductive capacity of the broodmare and detailed guidelines for effective breeding. It provides detailed protocols for vaccination and management of important reproductive diseases and disorders. The practical presentation includes thorough guidelines for the Breeding Soundness Examination. All aspects of assisted reproduction (embryo transfer, follicular aspiration, and oocyte collection) are evaluated and step-by-step procedures are provided.
