Introduction: Livestock anatomy is the basic science of animal husbandry and veterinary specialty, such as animal physiology, veterinary pathology, veterinary clinical diagnosis, veterinary obstetrics, livestock nutrition, livestock reproduction, livestock production and so on. At the same time, it is also the necessary basic knowledge for animal science and animal science researchers. In order to provide basic information for teachers, students, scientific workers and production technicians in the animal husbandry and veterinary front, we compiled the Atlas of Three-dimensional Anatomy of Sheep. This book consists of 12 parts, including sheep body, sheep skin system, digestive system, respiratory system, circulatory system, urinary system, nervous system, ewe reproductive system, ram reproductive system, endocrine system, immune system and exercise system, with 200 pictures. The picture material in this book is obtained by directly dissecting sheep and taking photos of real normal organs with digital cameras. When taking pictures, keep the basic shape, relative position and original color of living organs in normal physiological state of sheep. All the pictures are annotated in Chinese, Mongolian and English to expand the domestic readers and carry out international cultural exchanges.
