DEPTARTMENT OF VETERINARY PATHOLOGY

Department of Veterinary Pathology: Success of treartment of an ailment depends upon the knowledge of etiology and diagnosis of disease. Mandate of the department is to teach pathology of disease progression and practical training for identification of gross lesions, histopathological, microscopic and clinical post mortem examinations for diagnosis of diseases in animals. The department is well equipped with microtome, automatic tissue processor, microscope and a clinical pathology laboratory.

The Department has following sanctioned strength of Faculty:
