SLAUGHTER AND BEEF-MAKING QUALITIES OF FAT-TAILED AND ROUGH WOOL BREED BUCK LAMPS

Abstract

The intensification of mutton production in the South-East region of Kazakhstan conditions confirms the economic feasibility of processing young sheep up to 12 months old. However, exporters from the People's Republic of China are more interested in the meat of 1.5-year-old buck lambs. Scientific research aimed at increasing the meat productivity of 1.5-year-old buck lambs depending on the breed in the semi-desert zone of Kazakhstan have both scientific and practical significance. The experimental part of the work was carried out on the base of the “Yntykbay” farm of the Almaty region. Three groups of buck lambs were formed at the age of 1.5 years of the Edilbayev (first), Hissar (second) and Kazakh fat-tail (third) breeds. To assess the meat quality control slaughter of animals (3 species from each group) was carried out according to the method of VIZH. In the carcasses were determined morphological and varietal composition in accordance with GOST 7598-81. On specifics the animal meat qualities importance attached to the mass ratio of meat and bones. The carcass of animals, in which the maximum amount of meat and the least amount of bones and fat are formed, is most needed. The morphological composition of the carcass was determined at the Bakanas slaughter site by deboning individual varieties and cuts with the release of meat and bones from them, then their total mass of meat and bones in the carcass was found. The results of a study of the muscle and bone tissue ratio in carcasses of experimental buck lambs from different groups indicate that the morphological composition of carcasses without a fat-tailed of buck lambs of the first group is superior to buck lambs of the second group by 0.04 units and the third - by 0.61 units, and by the morphological composition of carcasses with fat-tail, by 0.06 units, and 0.78 units, respectively. This is due to the fact buck lambs of the first group are characterized by a lightweight skeleton.
