Abstract
Ninety-five cattle with various diseases, 28 healthy, and 10 grazing cattle were examined for serum concentration of aracid glycoprotein (α1-AG). It was assayed by the single radial immunodiffusion method. The serum α1-AG level was 236±68μg/ml in the healthy cattle, 843±532μg/ml in cases with bovine leukosis and 973±1099μg/ml in cases with inflammatory diseases. The α1-AG level was much higher in cattle with liver abscess, multiple abscess, gangrenous mastitis, eosinophilic myositis and pneumonia than that in normal cattle. However, the levels in cattle with cerebral abscess, meningitis or fatty liver were identical to those in normal cattle, and less in cattle with fat necrosis. No noticeable changes in α1-AG level were observed in healthy grazing cattle. From these results, serum α1-AG concentration seemed to be useful for the diagnosis of leukosis and inflammatory diseases in cattle.
