Department of veterinary Parasitology: Parasites significantly cause both morbidity and mortality and hence economic losses to livestock owners. This department offers courses to learn diagnosis, control, treatment and forecasting parasitic diseases in livestock and pets caused by protozoan, helminth and insect parasites. Practical training is imparted for identification of parasites and clinical examination of fecal, blood samples for parasitic infections in VCC and Animal Farm of the college. the department also participates in clinical cams organized by VCC.
The Department has the following sanctioned strength of Faculty:
Professor - 1
Associate Professor – 1
Assistant Professors – 2
