In the conditions of the Republic of Belarus there were analyzed high productive traits of meaty calves and cross breeds bred in accordance with a system cow-calf, as well as the possibilities of using veal meat obtained in ecologically safe areas for infant food production. At the age of 6,5-7 months the weight of fresh carcass of bull-calves of sharolez breed in comparison with aberdin-angus х black-motley herdmates was on 41,6 kg (Р less than 0,001) higher, carcass yield and slaughter yield – on 13,8% (Р less than 0,001) and 13,6% (Р less than 0,001), respectively. The fat content in sharolez meat was 4,9% against 8,9%; protein - 21,9% against 18,8%. The black-motley suckling bull-calves surpassed their herdmates which were grown up by technology of dairy cattle breeding at the age of 6-6,5 months according to indexes of weight of fresh carcass - on 16,3 kg or 21,7% (Р less than 0,01); according to indexes in a slaughter yield - on 16,6% (Р less than 0,001); and according to indexes meat flesh in a carcass - on 1,5%. According to quality indexes, amino acid structure, acceptable concentration of toxic elements content, pesticides, antibiotics, radionuclides and other harmful substances the veal meat of calves which were bred on a system a cow-calve in ecologically pure zones proved to be important meat raw materials to produce infant food products.
