ABSTRACT A survey was conducted to determine the occurrence of surgical disorders in five upazila veterinary hospitals (UVH) in Chittagong region. A total of 12,642 sick animals of different UVH were investigated in this study. The overall occurrence of surgical disorders was found 6.59% in Chittagong region where as 6.65% in hill tracts and 6.33% in plain land. The common surgical disorders recorded were myiasis (1.21%), tympany (1.13%), navel ill (0.99%), traumatic wound (0.79%), dog bite (0.73%), foot diseases (0.59%), abscess (0.32%), urolithiasis (0.27%), fracture (0.23%) and upward patellar fixation (0.11%). Out of 834 surgically affected animals, 51.32% were from hill tracts and 48.68% from plain land. The cases were higher in cattle (57.48%) than goat (40.18%), sheep (0.93%) and pig (1.40%). The percentage of surgical disorders was higher in female (60.28%) than in male (39.71%). The highest occurrence of surgical disorders was in summer season (16.96%) followed by rainy season (32.01%) and winter season (21.03%). It reveals that the highest occurrence of surgical disorder is claimed by myiasis (18.69%) in hill tracts. The results imply that surgical disorders affecting the animal population in these areas is a great threat for animal rearing. It could be mitigated by prompt surgical intervention of these defects.

INTRODUCTION Though livestock is an important component of the lifestyle of the tribal people, they do not know the modern rearing system of animal. Hill is one of the high altitudes where the incidence of falling is common. Fracture of bones is a feature of accidental surgical affection where ribs are more vulnerable (Duan et al., 2013). Surgical disorders are the major causes of fatality in animals if the animals are not treated in time. However, surgical disorders are major threat for our economy and failure of surgical intervention provides no alternatives except culling (Berge and Westhues, 1986). The surgical disorders hinder the growth, performance and economic value (Hossain et al., 1986). Surgical affection like hernia, atresia ani, navel ill, myiasis, humpsore, foot diseases, lameness and fracture are the diseases reported to be great loss to the people of Bangladesh (Hossain et al., 1986). External violence produces open wound in the skin and the incidence is more common in ruminants (Nooruddin and Dey, 1990). Healing of wound is one of the most complex biological events in living objects (Gillitzer and Goebeler, 2001) and wound may lead to serious consequences (Mashhood et al., 2006). Myiasis constitutes a major threat to the development of livestock industry and may occur all the year round in the tropics (Millikan, 1999). The occurrence of atresia ani is the second highest along the surgical affection of calves in Bangladesh (Das and Hashim 1996). In addition lameness in cattle is a serious problem and causes
