This study investigated the occurrence of surgical affections and their distribution on the basis of age, sex of the sheep, and seasons of the year. Retrospective data on surgical affections of sheep were recorded from all selected Upazila Livestock Office and Veterinary Hospitals of Mymensingh division from January 2021 to December 2021. To analyze the data, simple descriptive statistics were used. A total of 788 surgical cases in sheep were recorded. The overall occurrence of most common surgical affections in sheep were wound (29.18%), myiasis (15.10%), bloat (14.08%), subcutaneous cyst (12.56%), foot rot (8.24%) followed by abscess (6.47%), horn fracture (4.56%), atresia ani (3.93%), dermoid cyst (1.64%), dog bite (1.90%), overgrown hoof (1.52%) and gangrenous mastitis (0.63%). dermoid cyst (1.64%), dog bite (1.90%), overgrown hoof (1.52%) and gangrenous mastitis (0.63%) occurred less frequently in all Upazilas. The occurrence of surgical affections was higher in adult (73.35%) than young (26.64%). In adult sheep, incidence of myiasis, bloat, subcutaneous cyst, foot rot is more frequent. In female, the occurrence of myiasis, subcutaneous cyst, bloat and abscess were higher in comparison to those in the male sheep. The surgical affections are over presented in the adult sheep during the rainy season followed by the summer, autumn and winter. However, results of the present study reveal that there is a strong relation among the prevalence of surgical affections, sex and age of animals. The results imply that surgical disorders affecting the sheep in these areas is a great threat for animal rearing.
