A case of parakeratosis in pigs due to secondary zinc deficiency (zinc/calcium ratio 0.4 g/100 g; 68.7 mg zinc, 17.1 g calcium per kg food) is reported. Morbidity and symptoms were much more marked in growing boars than in female animals of the same age. In sows the disorder appeared ten days after the first symptoms were seen in the boars. Adult breeding pigs developed no signs of parakeratosis.
