Dietary Interactions Between Zn, Mn and Cu for Turkey Poults

Abstract

THE antagonism between Zn and Cu for animals has been well documented (Vohra et al., 1968), but most of these studies involved a high level of Zn. The antagonistic behavior of low levels of dietary Zn (up to 300 p.p.m.) on the low levels of dietary Cu (less than 1–25 p.p.m.) has been reviewed by Hill (1968). The role of high levels of EDTA along with the high levels of Zn and Cu on the mineral content of various tissues has also been studied (Vohra et al., 1968). No information is available between Zn and Mn interactions.The present investigation attempts to study the dietary interactions between supplementary levels of Zn, Mn and Cu (150 p.p.m., each), singly or in combination with each other, and 191 p.p.m. of EDTA-Na2 · 2H2 O on the growth, bone ash, Ca and P; tibia and liver Zn, Mn, Cu and Fe contents.EXPERIMENTAL…
