Gammaglobulin concentrations were measured in serum samples collected from 23 single-suckled beef calves immediately after birth and from 346 calves at 48 +/- 12 hours postpartum. Considerable variation in these levels appeared to be associated with age and breed of dam. There were also indications that they might be influenced markedly by herd management. These post-suckling gammaglobulin concentrations were of no value in predicting incidence or severity of undifferentiated neonatal diarrhea in the beef herd as a whole, or in the individual neonate.
对23头单哺肉牛犊出生后立即采集的血清样本以及346头犊牛产后48±12小时采集的血清样本进行了γ球蛋白浓度测定。这些水平的显著差异似乎与母牛的年龄和品种有关。也有迹象表明它们可能受到畜群管理的显著影响。这些哺乳后γ球蛋白浓度对于预测整个肉牛群或个体新生犊牛未分化新生儿腹泻的发生率或严重程度没有价值。
