Comparative experimental electrophoretic studies were carried out to establish the effect of ultraviolet treatment on cow's milk at various rates of irradiation (5, 10 and 15 min) with a view to raising and regulating the content of the total protein and the protein fractions in milk intended for the feeding of calves. Results showed that there were no substantial changes in the level of the total protein, the albumins having a rising trend that was manifested best at a 15-minute treatment. Most characteristic were the changes taking place in the immunoglobulin fraction which rose by 4.7 per cent. The beta-lactoglobulin fraction dropped by 4.5 per cent, on an average, at all rates of treatment, and the level of alfa-lactoglobulin at 5- and 10-minute irradiation underwent almost no changes, it rising by about 2.09 per cent, on an average, at 15-min treatment. Similar was the trend manifested by the proteoso-pepton fraction showing a rise as early as the first ten minutes of treatment.
进行了对比实验电泳研究，以确定紫外线处理对牛奶在不同照射时间（5、10和15分钟）下的影响，目的是提高和调节用于喂养小牛的牛奶中总蛋白和蛋白组分的含量。结果表明，总蛋白水平没有实质性变化，白蛋白呈上升趋势，在处理15分钟时表现最为明显。最显著的变化发生在免疫球蛋白组分上，其上升了4.7%。在所有处理时间下，β-乳球蛋白组分平均下降了4.5%，在照射5分钟和10分钟时，α-乳球蛋白水平几乎没有变化，在处理15分钟时平均上升了约2.09%。蛋白胨组分也表现出类似的趋势，早在处理的前十分钟就开始上升。
