Concentrations of total proteins, albumin, total serum immunoglobulins, urea and total lipids in the blood serum and glucose concentrations in the blood were investigated in the periods of milk nutrition and weaning, and the results were evaluated with respect to their differences from the range of reference values. Concentrations of total proteins (TP) in the blood serum significantly decreased if the starting values at the age of two weeks (65, 45 g/l) were compared with the values at the age of five weeks, and they began to increase to the age of 11 weeks. The average TP values at the age of 11 weeks were significantly higher (p < 0.01) than the starting values (Fig. 1, Tab. I). TP concentrations were above the upper limit of the reference range since weaning (nine weeks of age). Subnormal TP values were recorded in individual animals at the age of two, five weeks, at weaning, at 11 weeks in the animals on all-vegetable diet in 4.8%, 19.1%, 4.8% and 9.5% of the calves, respectively (Fig. 2). The albumin concentrations were increasing from the age of five weeks but the changes in the values were statistically insignificant and the average values remained in the reference range (Fig. 1). The reduced albumin concentrations were recorded in individual animals in 28.6% of the calves at the age of two weeks, in 19.1% of the calves at the age of five weeks, in 42.9% of the calves at weaning, and in 38.1% at the age of 11 weeks. The concentrations of total serum immunoglobulins (TS-Ig) were increasing since the animal collection with their growing age (Fig. 1) while in comparison with the starting values the increases were significant at the age of five weeks (p < 0.05), nine and eleven weeks (p < 0.01). The average TS-Ig values rose to the reference range at the age of five weeks. In individual animals, the reduced TS-Ig values were recorded in the serum at the age of two weeks in 71.4% of calves, at the age of five weeks in 42.9%, at weaning in 33.3% and at the age of 11 weeks it was only in 9.5% of the calves (Fig. 2). The urea concentration in the serum was decreasing from the age of five weeks to weaning. In comparison with the starting values, the differences in the average values were statistically insignificant and the average values remained within the reference range (Fig. 1).(ABSTRACT TRUNCATED AT 400 WORDS)
在牛奶营养期和断奶期对血清中的总蛋白、白蛋白、总血清免疫球蛋白、尿素和总脂质浓度以及血液中的葡萄糖浓度进行了研究，并根据其与参考值范围的差异对结果进行了评估。如果将两周龄时的起始值（65、45 g/l）与五周龄时的值进行比较，血清中的总蛋白（TP）浓度显著下降，并且在11周龄前开始上升。11周龄时的平均TP值显著高于起始值（p < 0.01）（图1，表I）。自断奶（九周龄）以来，TP浓度高于参考范围的上限。在全素食日粮的犊牛中，分别有4.8%、19.1%、4.8%和9.5%的犊牛在两周龄、五周龄、断奶时和11周龄时记录到TP值低于正常水平（图2）。白蛋白浓度从五周龄开始上升，但值的变化在统计学上不显著，平均值仍在参考范围内（图1）。在两周龄的犊牛中，28.6%的个体记录到白蛋白浓度降低；在五周龄时，19.1%的犊牛出现这种情况；断奶时，42.9%的犊牛出现；11周龄时，38.1%的犊牛出现。总血清免疫球蛋白（TS-Ig）浓度自采集动物后随着年龄增长而上升（图1），与起始值相比，在五周龄（p < 0.05）、九周龄和11周龄（p < 0.01）时上升显著。五周龄时TS-Ig的平均值得以升至参考范围。在个体动物中，71.4%的犊牛在两周龄时血清中记录到TS-Ig值降低，五周龄时为42.9%，断奶时为33.3%，11周龄时仅9.5%的犊牛出现这种情况（图2）。血清中的尿素浓度从五周龄到断奶时逐渐下降。与起始值相比，平均值的差异在统计学上不显著，平均值仍在参考范围内（图1）。（摘要截于400字）
