Increasing of beef cattle productivity in the Far North

Domestic beef cattle breeding are one of the fastest growing sectors of agricultural production in our country. Beef cattle breeding play an important role in organizing jobs in rural areas. The purpose of the research was to increase of beef productivity of cattle in the Far North. The object of the research was cattle of Kalmyk breed imported to the Republic of Sakha (Yakutia), as well as animals of the Yakut population of Simmental breed and aboriginal Yakut cattle as comparison groups. The biological and economic characteristics of Kalmyk cattle were studied, the efficiency of using cattle of this breed to increase beef production in the Republic of Sakha (Yakutia) was scientifically substantiated and experimentally proven. High adaptive plasticity of Kalmyk cattle to the natural and climatic conditions of Yakutia was determined. It should be noted as a result of the research that the lower cost of production of live weight gain was noted in Kalmyk cattle on average by 689.5 rubles lower than that of the Yakut population of Simmental breed and by 1,536.6 rubles less than that of Yakut cattle. At the same time due to the higher live weights the selling price of cattle of Kalmyk breed turned out to be higher than its herdmates. In particular, according to this parameter steers of Kalmyk breed exceeded their herdmates of Yakut and Simmental breeds by 17 887.6 and 3,999.1 rubles per 1 head, respectively. Consequently, the use of Kalmyk cattle for beef production under the conditions of the Republic of Sakha (Yakutia) turned out to be more profi table than Yakut cattle zoned in the Republic and the Yakut population of Simmental cattle.
