Down and wool efficiency of sheep

Abstract

In the Tuva Republic, one of the basic reserves for the production of a wide range of environment-friendly products, which are in demand in both domestic and world markets, is the revival of coarse-haired goat breeding. The study was conducted on goats of the following age and gender groups: bucks, does, doelings and bucklings. The down efficiency was studied by individual evaluation of down each animal had produced. After that during the spring shearing the amount of wool yield was evaluated. The down and wool efficiency of coarse-haired goats in the southern zone of Tuva was studied. The basic economically useful features were established: down and wool production in the context of age and gender groups, morphological structure of wool and thinness of different types of fibers. It was established that Tuvan goats have high potential of down productivity, characterized by a rather large amount of down produced (341.2-600.0 g). The content of down in the wool (82.2-91.1%), scouring yield from raw wool (95.9-98.0) and thinness (17.5-20.4 ym) corresponding to the cashgora goats were equal to or higher than the same parameters of local and other goat wool breeds in Russia and CIS countries.
