This book details the frontier technologies in the area of bovine reproduction. It describes the importance and significance of different technologies for improving reproduction efficiency in bovines. The book delineates the advancements in the technologies that are currently in use for faster multiplication of elite germ plasm including multiple ovulation and embryo transfer, ovum-pick-up, in vitro fertilization and embryo production, and semen sexing. Other emerging technologies, having potential for improving reproductive efficiency in bovines, including stem cells are also discussed with special reference to spermatogonial stem cells. Simple but effective tools having a great scope for day-to-day application in bovine farms for effective reproductive management like ultrasonography and thermal imaging are also covered in this book. The chapters on sperm transcriptomics, proteomics, metabolomics provide current developments in these areas and use of integrated approach for identification of fertility biomarkers. The chapters also describe technological advancements for early pregnancy diagnosis and offspring sex pre-selection in bovines. Additionally, this book discusses different sperm selection procedures including application of nanotechnology to obtain superior spermatozoa for assisted reproduction. Futuristic technologies including genomic selection and transgenesis are also discussed in detail. Finally, the book also elucidates a comprehensive description of challenges perceived with bovine reproduction and how effectively these technologies can help in improving fertility in bovines. 

This book provides updated information on the current concepts in bovine reproduction. It describes the complex issues associated with fertility and infertility in bovines and suggests strategies for achieving high reproductive efficiency. It discusses topics related to the fertility trend in bovines, estrus detection, controlled breeding, postpartum uterine health, uterine infections, and its therapeutic management. The essential roles of metabolic hormones on gonadal functions and fertility are also covered. Additionally, the book presents new insights in maternal recognition of pregnancy in bovines and suggest nutritional strategies to improve reproductive efficiency. The chapters on male fertility provide current information on semen cryopreservation, sperm quality assessment and measures to improve sperm fertility. A special chapter on intricacies in buffalo semen cryopreservation and measures to improve the quality of cryopreserved sperm is also included in this book. Lastly, the book introduces the immunobiological roles of anti-microbial peptides during sperm transport in reproductive tract and epigenetic bearing on fertility. This book is an invaluable resource for veterinary scientists, students and practitioners to understand the current developments in bovine reproduction for improving reproductive efficiency.
