The authors encountered 78 cases of pig from two swine herds with severe dermatitis, which had been fed with commercial rations. Main clinical signs were hard crust formation or erythema and papules on the skin and retarted growth. The skin lesions were visible on the limb joints in all cases. In some cases, however, crusts occurred on the tail, perineum, hip, ear, back, or neck. In one case the entire body surface was covered with thick crust. No mites were detected on the microscopic examination of skin scrapings. Histological examination of biopsies skin specimens taken from the lesions revealed typical parakeratotic changes: the cornified layer of epidermis was irregularly inreased in thickness and contained numerous nuclei. The provision of dietary supplementation with zinc sulfate and soybean oil for 10 days showed marked curative effect.
