The purpose of research is to study and conduct a comparative analysis of live weight, measurements, body build indices and wool fineness of goats of the Soviet wool breed of the Tuvan population and the Dagestan wool breed. The objects of research are the goats of the Soviet wool breed of the Tuvan population and the Dagestan wool breed. The study was conducted in 2020-2021 in the farms of Mongun-Taiginsky and Ulug-Khem kozhuuns (districts). The study was carried out according to generally accepted methods on the basis of the Tuva Scientific Research Institute of Agriculture. The live weight of goats was determined by the method of individual weighing of animals. Exterior assessment of goats was carried out, measurements were taken. After determining the measurements for a more complete characterization of the animals, the physique indices were calculated. Wool samples were taken in the spring before clipping, and the fineness of the wool was determined using a microscope. The obtained results of the study were processed by the method of variation statistics using the software package MS Excel 2003. Comparative data were obtained on live weight, body measurements and indices, and the fineness of the hair of goats bred in different regions of the Republic of Tyva. It was determined that Tuvan goats significantly exceeded Dagestan goats in oblique body length by 4.37 cm, in elongation index - by 6.1 cm, but were inferior in live weight by 4.33 kg, in chest girth behind the shoulder blades - by 3.11 cm and the churn index - by 13.08 cm. The study of the fineness of the wool revealed that the Dagestan goats had thicker (coarser) hair than that of the Tuvan goats, on the side by 6.26 µm and on the thigh by 4.33 µm. It was found that the imported goats adapted to the conditions of the Republic of Tuva and, in terms of productive indicators, have a higher live weight, have a larger chest girth, and, accordingly, their downsizing index was higher compared to local goats.
