The purpose of the study is the research of meat produc- tivity of young sheep of Khalkha breed and their half-breed hybrids from crossing with Suffolk sheep with different method of their feeding. The studies were carried out on the farm ‘Arvin Khur’ on the Selenginskaimag of the Mongolian Peo- ple's Republic and in the laboratories of Mongolian State Uni- versity in 3 groups of young growth aging from 3 to 8 months. The object of the research was purebred and cross-breed young Khalkha, of which three groups were formed by 5 ani- mals in each, two of which were represented by Khalkha and one by half-blooded Khalkha-Suffolk hybrids. At slaughter Khalha sheep at the age of 8 months after a day of fasting had live weight of 30.47 kg, purebred Khalkha rums which received in addition to pasture rapeseed cake as feeding had34.25 kg of weight and half-blooded Khalkha-Suffolk crosses- 45.10 kg. The analysis of chemical composition of sheep meat showed that in the samples of Khalkha sheep animals which had grazed on natural pastures somewhat less mois- ture contained than in purebreds with 0.61 %, semicircular peers - 1.31 %, and more fat - 1.08 % and 2.01 % respec- tively. At the same time, the samples of meat of half-blooded sheep contained by 0.45 % protein and by 0.26 % of ashes more than purebred Khalkha peers, which resulted in 6.6 % decrease in their caloric content. The data presented show that additional feeding of Khalkha breed rams with rapeseed cake promotes fuller satisfaction of need of an organism ofanimals for nutrients, increase of intensity of their growth and meat efficiency.
