This manual, written in a clear and accessible style, aims to provide a comprehensive understanding of common reproductive issues in dairy and pet animals. Designed for field veterinarians, reproductive health program participants, officers, and students, it offers the latest information on diagnostic and therapeutic approaches for gynaecological disorders, such as anestrus, repeat breeding, placenta retention, cervical/uterine prolapse, abortion, endometritis, metritis, and uterine torsion in cows and buffaloes. Additionally, the manual covers common reproductive problems and their management in bitches. The knowledge and experiences gained by the authors during their years of work at polyclinics, dairy farms, and in the fields have been incorporated into this manual, making it a valuable resource for anyone dealing with these issues. We believe that this manual will enhance readers' knowledge and confidence in addressing these challenges.
