The article considers the quality of beef carcasses from cattle of Kazakh white-headed and Kalmyk breeds, bred mainly in Kazakhstan, as well as the results of the study of chemical composition of meat cuts, yield and meat index of beef cuts on the bone and boneless, allocated in accordance with the international standard UNECE. The chemical composition of cuts was determined: moisture, fat, protein. Methods of moisture determination – according to “GOST 9793-2016 Meat and meat products. Methods of moisture determination”.
