Abstract :
In the current study, 490 cattle (293 female and 197 male) were inspected at Urmia abattoir. In these inspections, 17 cattle (3.4%) had splenic lesions and that of these, 6 animals had some lesions in other organs in addition to the spleen. Tissue sampling from abnormal spleens was performed. After tissue fixation, sections with 6 μ in thickness were prepared and stained by hematoxylin and eosin method. In the macroscopic inspection lesions such as splenomegaly, change of tissue consistency, color change and cyst had more abundance compared to other lesions. In the microscopic pathological evaluations, hemosiderosis, parenchymal fibrosis, tumor, necrosis, hemorrhage and focal necrosis areas were found in damaged spleens. In statistical analysis, color changes of the spleen between breed groups and consistency change of the spleen between sex groups showed significant difference (p<0.05). Indeed, abundance of injured spleens had a significant relation with age and sex of slaughtered cattle (p<0.05).
