Equine Reproduction
edited by
Angus O. McKinnon

Equine Reproduction is divided into three main sections:

• the mare
• the stallion
• the neonate

Each is equally important to veterinarians involved in equine reproductive practice. The discussions of the mare and stallion are divided into the following topics:

• anatomy, physiology, and endocrinology
• breeding management
• diseases of the reproductive tract
• reproductive surgery

Additional topics in the section on the mare are pregnancy, parturition, and the puerperal period. Discussion of the neonate is divided into neonatal care and diseases according to body systems.
