Reproductive problems of caprine, ovine, bovine and equine significantly reduce their productivity which is of great concern of production worldwide, because most reproductive problems adversely affect the future fertility. A four year retrospective study of reproductive problems of caprine, ovine, bovine and equine presented to Nyala Veterinary Hospital, South Darfur State, Sudan was conducted with the objective to determine the prevalence of reproductive problems in study animals between January 2012 and December 2015. All Data about animals were collected from case registration books and entered into Microsoft excel sheet and analyzed based on the year of study, the disease frequency and, species of the animals. Total of 362 reproductive problems of caprine, ovine, bovine and equine were recorded between January 2012 and December 2015 from a total of 5001 examined for different clinical cases at Nyala Veterinary Hospital. This study were found to have reproductive problems comprising mastitis 110 (36.42%), dystocia 67 (22.19%), retention of placenta 56 (18.54%), brucellosis 21 (6.95%) and abortion 15 (4.97%) in caprine and Orchitis 5 (33.33%) in equine. In conclusion, from this study, reproductive cases were most prevalent in caprine than bovine, ovine and equine. Therefore, Major causes of reproductive problems especially in caprine should be identified and followed by appropriate measures according to the problems, to minimize the reproductive loss.
