Economy of many countries is established on animal production and the farm biotechnology. Physiology, endocrinology and fertility problems, veterinarians and farmers would be aware of those. The aim of this book is to highlight the science of gynecology and reproduction through approaching the right way to improve the animal management and the reproductive parameters. Assisted-reproductive technologies (ART) were developed to improve the animal reproduction as possible as we can. Most of these criteria are involved in this book, we have to begin from the point which others have an end. My greeting to anyone who appreciates the animal. Good luck!
