Features: This book can serve as a reference for teaching and research for faculty and students of higher and secondary agricultural institutions, as well as for relevant researchers. It is also suitable for technical personnel, veterinarians, management staff, and cattle and sheep farmers to study and reference. Animal reproduction is a discipline that systematically studies and introduces the reproductive physiology, reproductive techniques, and reproductive diseases of cattle and sheep. It holds significant importance for further research and understanding of the reproductive patterns of cattle and sheep, improving their reproductive rates, advancing the development of cattle and sheep farming, promoting strategic adjustments in the agricultural and household economy, broadening income channels for rural households, implementing integrated agriculture and animal husbandry, and achieving sustainable agricultural development. The book is divided into five major parts and twenty chapters.
Part 1 focuses on the occurrence, formation, estrus, ovulation, fertilization, pregnancy, parturition, lactation, and suckling of cattle and sheep, as well as the hormonal regulation of these physiological phenomena. Part 2 systematically elaborates on practical techniques and high-tech applications, including estrus detection and control, semen preservation, pregnancy diagnosis, assisted delivery and postpartum care, and biotechnologies of embryos and gametes. Part 3 emphasizes the occurrence and treatment of general reproductive disorders and diseases in cattle and sheep, as well as the prevention, diagnosis, and treatment of reproductive infectious and parasitic diseases. Part 4 provides a detailed explanation of reproductive performance indicators in cattle and sheep, statistical calculation methods, current technical levels, factors affecting reproductive performance, and measures to improve reproductive efficiency. Part 5 focuses on reproductive management, introducing existing "standards," "guidelines," and "procedures" related to reproduction to serve as references for production management, ensuring that reproductive techniques are integrated into scientific, standardized, and institutionalized production management.
