This work was conducted on a ttoal 31 calves of the native breed, their age were between 6 and 18 months. Seven animals showed the typical IBR. MD - VD virus infection symptoms. Eight calves showed severe febrile conditions without exhibitin the apparent clinical signs and another eight calves seem to be in the convales cent stage and seem to show symptoms of recovery. Eight calves were kept as control throughout the whole time of the study. Serum protein electrophoretic values are presented for the clinical apparently healthy calves and the other groups, using a standardized method for protein analysis and fractionation.
No significant cahnges is either relative or absolute amounts of serum proteins and albumin were detected in the serum of the affected calves when compared with the presumably, healthy calves. Highly significant rise in the 1 and 2 globulin fractions was observed in all affected groups indicating severe inflammatory processes accompanied by necrosis. Severe depression of B-2 glublin fraction was observed in the convalescent group, while total absence of the same fraction in both diseased and feverish group was evident.
