Department of Internal and Preventive Medicine, College of Veterinary Medicine, University of Mosul, Mosul, Iraq

Abstract

The affected calves showed clinical signs including presence of vesicles at the bucal cavity and hoof (90.7%), fever (36%), salivation (32.9%), depression (20.5%), Anorexia (19.6%), loss of body weight (7.94%), lamness (15.9%), lesions at the muzzle (15.3%), presence of the lesions at the feet (6.0%), prostration (4.7%), diarrhea (3.3%), presence of the lesion at the mouth cavity (3.0%), paralysis of hind quarters (2.2%) and sudden death (1.6%). There was significant increase in the rectal temperature, respiration rates, and heart rates in the infected animals compared with control group. Recovered animals appeared some diseases including theileriosis (40.4%), tympany (22.8%), pneumonia (19.9%), foot abscess (14.7%), and babesiosis (2.2 %). The mortality rate varied between 3.4% to 27.9% in different herds and the mean was 3.3 % in all herds.

There was significant relationship between age of animals and the incidence of the disease.
