Electrophoretic pattern of the blood serum proteins from 8 chicks of 1, 7, 14, and 21 days of age was determined by crossed immunoelectrophoresis. The chicks at 1 day of age had low levels of albumin and high levels of IgG, beta-lipoprotein, and transferrin. The albumin increased gradually to attain high levels by 21st day. The IgG levels, however, showed a considerable decline up to the 14th day. The beta-lipoprotein levels also decreased considerably on the 7th day. The transferrin levels showed a gradual decline. The IgM appeared as a faint precipitate on the 7th day. The cholinesterase showed transition from an initial low level at 1 day to a subsequent relatively high level at 7 to 21 days. The arylesterase in day-old chicks was higher than in chicks of 7 to 21 days of age.
通过交叉免疫电泳法测定了1日龄、7日龄、14日龄和21日龄的8只雏鸡血清蛋白的电泳图谱。1日龄雏鸡的白蛋白水平较低，而免疫球蛋白G、β-脂蛋白和转铁蛋白水平较高。白蛋白水平逐渐升高，到第21天时达到较高水平。然而，免疫球蛋白G水平在第14天之前显著下降。β-脂蛋白水平在第7天也大幅下降。转铁蛋白水平呈逐渐下降趋势。免疫球蛋白M在第7天出现微弱沉淀。胆碱酯酶显示出从1日龄时的初始低水平转变为7至21日龄时的相对高水平。1日龄雏鸡的芳基酯酶高于7至21日龄的雏鸡。
