Abstract

The article presents data on the change in the tone of different types of wool fibers along the length of the fiber in different sex and age groups of the Tajik wool breed of goats. It is established that the tone of the same fibers is not the same throughout their length: the decrease in tone occurs from the top to the base of the fiber, the greatest thinning occurs in the winter season, which indicates insufficient energy consumption of feed by goats during this period.
