Tannery productivity of Altai White Down goats

Abstract

Goat breeding is an important branch of animal husbandry. Most of the goat population is kept in private farms. The total number of goats is 1.85 million animals. In 2016, a new breed of goats was approved — the Altai White Downy, total number of which is about 18 thousand goals. The article presents data on the study of leather productivity and skin quality of Altai goats by the basic physical and mechanical indicators. The goat hides were examined at the age of 1.5 years, 10 heads of pairs of analogues. It was found that the ratio of the mass of the studied skins to the slaughter mass is on average 9.4±0.26%, and their thickness in different topographic areas from 1.2 to 4.5 mm, which characterizes the goatskins as thick and heavy. All the studied samples were assigned to the steppe class I, and in size to group I. One of the drawbacks of GOST 28425-90 is that goats with a size of more than 24 dm2 belong to group I; requirements for II, III, and IV groups, unlike the skins of other animal species, are absent. When goats are selected, such an additional sign of productivity as the thickness of the goatskin in the area of cheprak can be taken into account.
