"Essentials of Domestic Animal Embryology" is a comprehensive, modern treatment of the subject dealing with all organ systems and including important molecular aspects of animal development. Written with the student in mind, the text covers embryology of the domestic species, both general (development from formation of the gametes, through fertilization and initial embryogenesis, up to organ formation) and special (development of the organ systems). It also includes sections on teratology, assisted reproduction technologies, societal relevance, and the implications for current veterinary practice of a long-established science. Students of veterinary medicine, animal science, biomedical sciences and biotechnology, at both undergraduate and graduate stages of their careers, will find this volume essential for their needs. The international experience of the authors has been applied to produce a textbook of international relevance, likely to remain an important resource for many years to come.
