The aim of the study was to determine the degree of differentiation between selected histomor-phometric characteristics of common fox (Vulpes vulpes) skins with regard to the origin of animals(farmed vs wild population). Skin size parameters with evaluation of hair coat quality, trace elementcomposition of hair, and histomorphometric characteristics of cutaneous tissue were studied.The domestic population of wild foxes was characterized by low body weight and poor hair coatquality, which showed considerable felting (10–35% of skin area), absence of down, and deficiency ofelements needed for proper hair development. Histological analysis of cutaneous tissue in wild foxesshowed a lower number of bundles per tuft (P≤0.05), a lower number of down hair per tuftand bundle (P≤0.01) and a greater number of sebaceous glands, which had greater length (P≤0.01)and area (P≤0.05). Analysis of the level of trace and major elements in the hair of wild and farmedfoxes revealed highly significant differences in the amounts of iodine, lead, selenium and sulfur. All ofthese elements were more abundant in farmed foxes except for lead, which was higher in wild foxes
