Cattle breeding is undertaken chiefly to improve cattle progeny. The ability of a cow to successfully mate, conceive, give birth to and raise a healthy calf each year is essential to economical beef production. A good understanding of anatomy and physiology of both the male and female is helpful in successfully managing reproduction. In order to manage cattle reproduction and the specific problems that arise, it is important to understand the underlying physiology of the reproductive process. Thus, this text aims to provide an integrated overview of the subject of bovine reproduction, describing the normal function of the reproductive system together with its modification by pharmacological, technological and management techniques in relation to the central theme of reproductive efficiency. This book continues to provide a general background to the field of cattle reproduction for agricultural and animal science students and as an introductory text to veterinary students embarking on a career in reproductive research.
