Feeding ability and meat efficiency of purebred and crossbreed young growth at rapeseed cake feeding

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...
