Quality of skins of commodity young stock of silver-black foxes grown in shads of different constructions

Abstract

The purpose. To compare productivity of commodity young stock of silver-black foxes contained in standard 2-rows and redesigned from glasshouses 4-rows shads in different conditions of daylight illumination. Methods. Zootechnical, organoleptic, morphometric, physical methods of researches. Animals of control group were grown in standard 2-rows shads, of experimental — in 4-rows redesigned shad. Results. In standard 2-rows shads the maximum index of illuminance made nearby 1500 luxes, in 4-rows — less than 200 luxes. Flat-dry skins of commodity young stock of silverblack foxes grown in standard shads, were more longly, more widely — their square was more in comparison with skins of animals grown in 4-rows redesigned shad. However they were characterized by the worst colour, silveriness and had more imperfections of fur. Conclusions. Growing commodity young stock of silver-black foxes in standard 2-rows and redesigned 4-rows shads not only creates different conditions of daylight illumination, but also causes formation of fur products of different quality.
