This reference on veterinary embryology covers general embryology, i.e. the development from the formation of the gametes over fertilization and initial embryogenesis up to the stage where organ formation is initiated, and special embryology, i.e. the development of the organ systems. Moreover, the book also includes a section on teratology, one on assisted reproductive technologies and one on veterinary and societal aspects. Written with the veterinary student in mind, this textbook is written in an accessible style with high quality colour illustrations and line drawings.
- 300 high-quality colour illustrations
- Written for undergraduates and invaluable for graduates wishing to brush up
