Parakeratose in einem biologisch wirtschaftenden SchweinemastbetriebWernerHagmüllerauthorSonjaWlcekauthorDue to the supplementation of zinc to their diets, Parakeratosis is rarely found in pigs. On an organic farm in Austria a farmer altered the pig’s fattening diet and omitted mineral supplementation from the diets. Three weeks later skin alterations were seen. After the administration of tetracyclin and Ivomec-premix by a veterinarian the skin abnormalities failed to improve and the pig’s feed intake decreased markedly. The veterinarian diagnosed parakeratosis. After administration of zincoxid feed intake increased. 6-8 weeks after treatment the pig`s skin alterations disappeared and health was restored.
