Parakeratosis or Zinc Deficiency Disease in the Pig.

SummaryThe parakeratosis syndrome was produced in pigs on rations containing 34 to 44 ppm of Zn. The level of Ca and/or P affected the incidence and severity of the disease. Supplementing the diet with .02% of ZnCO3 (or .01% ZnCO3 in a trace mineral mixture) cured or prevented the disease. The zinc-supplemented rations produced excellent growth in pigs.
