Blood serum samples were obtained from 114 crossbred calves on a feed trial under feedlot conditions at the end of a 56-day feeding period. Average values for 19 blood components were determined. The effects of the 3 trial rations and 2 electrolyte treatments were analyzed. Except for inorganic phosphates, urea nitrogen, cholesterol, glucose, alanine aminotransferase, and alkaline phosphatase most mean values were similar to those in dairy cattle. Urea nitrogen values differed significantly (P less than 0.05) in animals fed different rations apparently reflecting the crude protein content of each ration. The mean values presented can be used as base-line data for comparison with other similar studies or with values from diseased animals.
在育肥场条件下进行的一项饲养试验中，在56天的饲养期结束时，从114头杂交犊牛身上采集了血清样本。测定了19种血液成分的平均值。分析了3种试验日粮和2种电解质处理的效果。除无机磷酸盐、尿素氮、胆固醇、葡萄糖、丙氨酸转氨酶和碱性磷酸酶外，大多数平均值与奶牛相似。饲喂不同日粮的动物尿素氮值差异显著（P小于0.05），这显然反映了每种日粮的粗蛋白含量。所呈现的平均值可作为基线数据，用于与其他类似研究或患病动物的值进行比较。
