The study of the formation of mink hair with the use of mineral sorbents as a feed additive in the animal farms of the Cherkassy Regional Consumer Union found that the morphometric characteristics of juvenile hair of young mink of the studied groups at the age of 45 days in the context of the studied groups did not have a significant difference in terms of hair length (P < 0.95). The average value of the length indicator for the outer hair was 12.5-13.5 mm, for the guard hairs - 9.3-10 mm, downy hairs - 5 mm. The probable difference turned out to be only in terms of the thickness of the guard and down hair, which can be explained by the individual characteristics of the animals. At the age of 60 days, the prevalence of hair of various categories of animals of the experimental groups (P> 0.95) was noted in terms of the length of hair. The average value of the length indicator for the outer hair was 14–15 mm, for the axial - 10–11 mm, and downy - 6–8 mm. When comparing the average values of the thickness of hair of different categories at this age there is a probable difference. A similar trend continued until the beginning of the molting of animals. At the age of 90 days, there is a significant difference between the research and control groups only along the length of the guard hair (P> 0.99 ... 0.999) and in the thickness of the guide and guard hairs. The molting of animals of the studied groups began on August 17 and ended on October 20, the duration of this indicator varied within groups of 53-65 days. When comparing the mean values, no significant difference was found (P <0.95). The results of the correlation analysis showed the presence of a possible relationship between the dose of the drug and the length of the guard hair (r = 0.51, P> 0.99) and the start date of the molting process (r = 0.39, p> 0.99). In general, the influence of the feeding of mineral sorbents on the morphometric parameters of fur is noted. The effect of the drug on the presence of lifetime defects in mink fur has not been established.
