The experiment was conducted on 3 groups of calves. Each group composed of 6 calves from 2-16 weeks of age. In the first group the calves were fed whole milk--milk replacer Mlekomiks, in the second--whole milk and the third group--milk replacer Mlekomiks. Throughout the experiment all calves were fed good meadow hay and concentrate ad libitum. Level of total protein was similar in all examined groups of calves but particular protein fractions showed highly significant differences (P less than than or equal to 0.01) due to used diet. Such differences were obtained in level of urea as well.
该实验在三组犊牛上进行。每组由6头2至16周龄的犊牛组成。第一组犊牛饲喂全脂牛奶——代乳粉Mlekomiks，第二组——全脂牛奶，第三组——代乳粉Mlekomiks。在整个实验过程中，所有犊牛均可自由采食优质草地干草和精饲料。所有检查的犊牛组中总蛋白水平相似，但由于所使用的日粮，特定蛋白质组分显示出高度显著差异（P小于或等于0.01）。尿素水平也获得了类似的差异。
