Abstract
The diameter and evenness of fibers in the staple and along the fleece are taken into account in selection and breeding work and are most important for evaluating wool as a raw material for the processing industry, as they affect the technology of its processing. At the same time, the accuracy of measuring the diameter of the fibers is ensured by the use of instrumental research methods. There-fore, the purpose of the work was to establish the physical and technical indicators of wool in the rams of the Gorno-Altai breed to improve the efficiency of the selection of animals that meet the requirements of the breed standard. The objects of research were wool samples obtained from the side and thigh of the main and replacement rams of the breed bred in 4 agricultural enterprises of the Altai Republic. Fineness determination was carried out on the OFDA-2215 device in the laboratory for testing and certification of wool quality of the All-Russian Research Institute of Breeding. It has been established that in terms of average fineness and equality of wool, sheep of the Gorno-Altai breed are characterized by a fairly large factory variety, but are within the parameters of the type desired for the breed and have semi-fine or semi-coarse homogeneous wool. On average, the diameter of the hair on the side was 30.60 μm, on the thigh – 33.25 μm, the standard deviation of diameter varied in the range of 6.98-8.57 μm.
