Abstract :

In this study, livers of 1286 cattle are inspected grossly during five months according to their color and consistency changes with referring to Urmia Abattoir. Among the inspected carcasses, livers of 110 cattle had lesions. The collected tissues samples of confiscated livers are placed in 10% buffered formalin as a fixative solution and are sent to pathology laboratory for preparation of tissue microscopic sections with a thickness of 6 μm. Pathologic sections are stained by haematoxylin and eosin (H&E) and periodic acid schiff (PAS) methods. The most pathologic changes in cattle livers are fatty change (33.6%), congestion (27.3%), hepatitis and cholangitis (25.5%), and bile duct hyperplasia (39.3%) respectively. Results of this survey showed that there was a significance relation (p
