Effect of Zinc upon Growth and Incidence of Perosis in Turkey Poults.

Abstract

Turkey poults which were fed a purified ration containing an isolated soybean protein (Drackett C-1) developed perosis. The addition of zinc to the ration improved growth and markedly reduced the incidence and severity of the perotic condition. Both zinc chloride and zinc oxide were effective and potassium chloride in addition to a zinc salt was no more effective than zinc salt alone. Approximately 40 ppm of zinc, in addition to the 26 ppm contained in the basal ration, were required for optimum growth.
