The aim of this study was to determine the frequency and histopathology of abomasal ulcers in the slaughtered cattle in Tabriz in 2015-2016. A total of 288 cattle (197 males, 91 females) were randomly selected to evaluate the abomasal ulcers during four seasons. The age, gender, location and type of ulcers were recorded. All types of ulcers that were observed in different abomasa were randomly selected for the histopathological examination. The data were analyzed using theChi-square test. In this study, 235 (%81.6) cattle had abomasal ulcer which all of them were type 1 ulcers, but the other type of abomasal ulcers were not observed. Among the type 1 ulcer, the frequency of type 1a (122 cases) was significantly more than the others. Also, the abomasal ulcers in summer were significantly higher than in other seasons. There was no significant relationship between age and abomasal ulcers, but a significant relationship was found between gender and abomasal ulcers. The odds of having an abomasal ulcer for female were 2.26 timeshigher than for male. The distribution of ulcers was differed in the various part of theabomasum and in the pylorus was observed more than others (P<0.05). In addition, the histopathological examination was done to confirm the presence of type 1 ulcers which was in accordance with macroscopic classification. The results of this study showed that a high percentage of cattle abomasa examined in this area has the type 1 abomasal ulcers.
