Abstract: The results of the studies showed a positive effect of a new multicomponent concentrate "Zolotoi Felutsen" on meat productivity of black-and-white bull calves. Bull calves, consuming fodder concentrate at the dose of 50 g, 75 and 100 g/1 kg of mixed fodder had different live weight gain compared to the control animals. The average daily gain was 41, 106 and 118 g. Live weight gain at the age of a year and a half was 16.0, 39.7 and 42.7 kg. Visual evaluation proves good body development of animals of all the groups. At the same time, bull calves of the 1-3 groups had better meat production traits. Compared to the control animals their height at the shoulder was more by 1.7-2.1 %; chest width by 3.6-4.9%; chest depth by 1.7-2.1%; chest girt by 1.4%; body length by 2.7-3.0%; quarter size by 3.5-3.7%. The results of the sample slaughter of young animals at the age of 18 months in comparison with those of the control stock were as follows.
