Introduction

  • Zinc is required for the proper function of a wide variety of enzymes with roles in gene expression (DNA and RNA metabolism), appetite, Vitamin A metabolism and immune system function. 
  • Pastures in the UK usually contain adequate levels of zinc (over 20mg zinc/kg DM).
  • Zinc levels in feedstuffs are closely correlated to zinc levels in the soil and plant maturity. Hay and straw tends to have low levels of zinc.
