The studies on the effect of dry pelleted feed on the performance of arctic foxes and some of their morphological-biochemical blood indices were divided into two stages. In stage one 200 foxes aged 8 weeks were allocated to two equal groups. The control group received traditional feed. The experimental factor was pelleted feed given to the experimental group. This stage also included: determination of the body weight of foxes at the beginning and at the end of the studies, evaluation of conformation and pelt quality, determination of morphological and biochemical blood indices. The indices of reproduction performance of the experimental animals were determined in stage two. Feeding pellets to arctic foxes caused a decrease in their final body weight and pelt length, but improved the in vivo and post-slaughter parameters of fur quality. The experimental factor affected neither the morphological-biochemical blood indices analyzed in the experiment, nor the reproduction performance of foxes.
