Abstract: The roles of zinc in rising of livestock and poultry were reviewed. By way of affection to enzymes zinc realize its multifunction to the derma, reproductive abilities and arthroses in domestic animals and poultry, especially to chicken, swine and cow. Corresponding nutritional diseases can be caused and the patients even can die when zinc is supplied either deficiently or excessively. The bioavailability of zinc is dependent upon species of zinc compounds, feeds, animal individuals and other nutrients as well as minerals given to the animals. Zinc amino acid complexes not only have the functions as zinc additives but also can significantly enhance the productive performance of animals and cause less pollution to environment than that of inorganic zinc, which accords with the requirements of green breeding trend but it still needs a long way to go to develop and explore the practical utilities and physiological functions of zinc amino acid complexes.
