Biochemical blood test analysis results of cross-breed bull-calves, obtained from crossing Simmenthal cows with both Hereford and Charolais bulls, are provided in the article. Data on both protein and lipid content metabolism indices in various age periods in bull-calves blood are also provided. It has been discovered that urea content in blood of new-born bull-calves exceeded its content in one-year-old bull-calves by 65.4-80.1%, and glucose content - by 66,6-112,7% (P ≤ 0,001). As compared to new-born bull-calves content nonesterified fatty acids in blood of a day-old bull-calves increased by 17,7-39,0%, and in a month-old bull-calves - by 32,3-48,8% (P ≤ 0,01-0,05).
