Seventy-eight Friesian bull calves were purchased in a cattle market and housed in a veal calf unit. There was a correlation between the risk of enteric disorders and the quantity of milkreplacer supplied during the first fortnight. The risk of respiratory disease did not show significant correlation with- and globulin levels and with serum protein and IgG1 levels at the time of purchase. No significant relationship could be shown to be present between growth and serum protein, IgG1, or globulin levels. Calves with diarrhoea during the first three weeks showed an average decrease in growth of 1.6 kg during the first ten weeks (p greater than 0.1), and calves with respiratory disease showed an average reduction of growth of 5.4 kg during the period from 0 to 10 weeks (p less than 0.01). There was no evidence to suggest that the low serum protein levels during the first six weeks of the fattening period are affected by a lower of higher feed intake during the first fortnight.
在一个牲畜市场购买了78头弗里斯兰公牛犊，并安置在一个小牛肉犊牛舍中。在头两周内，肠道疾病风险与代乳品供应量之间存在相关性。购买时，呼吸道疾病风险与球蛋白水平、血清蛋白和IgG1水平无显著相关性。生长与血清蛋白、IgG1或球蛋白水平之间未显示出显著关系。前三周出现腹泻的犊牛在前十周平均生长减少1.6千克（p大于0.1），患呼吸道疾病的犊牛在0至10周期间平均生长减少5.4千克（p小于0.01）。没有证据表明育肥期前六周的低血清蛋白水平受头两周较高或较低采食量的影响。
