Comparative analysis of productive qualities of Sables without gray hair and with different degrees of gray hair in JSC «Plemzverosovkhoz» Saltykovsky»

The pride of Russia has always been sable. Sable is unique not only in the quality of its fur, but also in the fact that almost the entire range of its habitat is located on the territory of our country. It was in our country that this animal was first bred in captivity. In this regard, Russia has long had a monopoly on the production of sable skins. In 1969, the black sable breed was approved, and in 1998, the «Saltykov» type of sable was approved. JSC «Saltykovsky Breeding farm» has created a unique herd of dark Sables with evenly spaced gray hair, the skins of which are valued at auctions by 10–30% more expensive [2].
