The aim of this article was to determine the morphometric properties of wool coat in relation to weight and age of animals. The objects of the study were Tuvan coarse-wooled bucks from farms located in the Republic of Tyva (Russia) on the border with Mongolia. Goat wool samples were taken from the side behind the scapula for examination using an OFDA 2000 optical hair diameter analyzer. It was found that there is no correlation between body weight and down length, with down length having a correlation with total wool length at the 0.48 level. The average diameter of the fibers in the staple correlates positively with the peak value of the histogram (0.47), while the dependence of down length on its diameter is weakly negative (–0.19). It was found that there are animals in the population with a down hair length of more than 7 cm, and with a histogram peak of 16 μm. We believe that there is genetic potential in the population of aboriginal Tuvinian coarse-wooled goats to create herds with down productivity with fine down (cashmere) free from transitional type fibers and satisfying industry requirements in terms of length.
