Evaluation of amino-acid, mineral, and vitamin content, as well as indexes of meat safety obtained from young stock of cattle of different genotypes in accordance with possibility of its application as raw material for baby food production was realized in the conditions of the Republic of Belarus. In course of study there were used bull calves of white-and-black breed, Limousin breed and their crossbreeds. Research results showed that young stock of Limousin breed, Limousin x white-and-black crossbreds, and white-and-black breed (control group) gave high quality meat. In meat of animals of experimental groups there was stated high quality of almost all nonessential amino acids and nonreplaceable amino acids, in meat of crossbreeds there was noted considerable increasing of polyunsaturated fatty acids. In it there was 12,31% of linoleic acid against 4,75 in Limousin breed and 2,77% in white-and-black breed; and eicosatetraenoic acid – 2,4% against 1,24% and 0,7%, respectively. Also in meat of experimental bull calves there was stated higher content of vitamins, calcium and phosphorus, while the content of cuprum and zinc decreased
