This article provides information about the reproductive capacity of minks as a result of the mating of purebred and crossbred females of the STK with males of the Scanbrown breed. The authors found that when crossing both purebred females of the STK and crossbred (F1 ½ ScBr), their fecundity increases in comparison with purebred mating. However, at the same time, the percentage of prokholostevshih, skipped females and females with dysfunctional births also in-creases. In addition, when crossing, the specific weight of stillborn puppy’s increases.
