Abstract: A traditional technology used in beef raising in Kalmykia and Siberia cannot be copied and won’t be effective in Yakutia due to its objective peculiarities. Therefore, it is necessary to use special principles and create a unique technology and a specific Yakutian type of meat cattle. High-quality marble meat production is determined by the genetic potential of the selected breeds (Kalmyk, Yakutian) and the methods of cattle raising (aimed at increasing heterozygosity). The article contains experimental data on selection and genetic parameters of productive characteristics of the young stock of meat breeds (Hereford and Kalmyk) in Yakutia. The research is based on the groups each composing 10 animals of bull calves and heifers aged 6.9 months. Groups equity is achieved through the use of couples of analogous animals. Animals were raised using the meat cattle raising technology, in equal breeding and raising conditions. Diets meet the requirements of the Federal Science Center for Animal Husbandry in food value, energy level and nutrient content. It is the first time when selection and genetic parameters of production qualities of the young stock of meat breeds (Hereford and Kalmyk) are studied in Yakutia. Weight growth of the young stock of meat breeds shows that the body weight of bull calves and heifers at birth was 19.2 - 20.8 kg, at the age of 3 months - 53.3 - 55.5 kg, at the age of 5 months - 109.7 - 117 kg correspondingly.
