Between December and April there was a decrease in the concentration of gamma-globulins in the blood serum of 2 to 3 day old calves. 2. Calves with more symptoms of enteritis or omphalitis had lower concentrations of gammaglobulin. 3. Calves with higher body temperatures had lower concentrations. 4. Calves from primiparous cows had lower concentrations than calves from pluriparous. 5. Calves from young dams had lower concentrations than calves from older dams. 6. Calves, which were born by caesarian section had lower concentrations than calves which were born spontaneously or with other assistance.

在12月至4月期间，2至3日龄犊牛血清中的γ球蛋白浓度有所下降。2. 患有更多肠炎或脐炎症状的犊牛γ球蛋白浓度较低。3. 体温较高的犊牛浓度较低。4. 初产母牛所生犊牛的浓度低于经产母牛所生犊牛。5. 年轻母牛所生犊牛的浓度低于年长母牛所生犊牛。6. 通过剖腹产出生的犊牛浓度低于自然分娩或借助其他辅助方式出生的犊牛。
