The function of the essential trace element Zinc in animal metabolism is highly manifold. Zinc influences as a catalytic, structural and regulatory element the activity and stability of enzymes and the metabolism of nutrients. Further more Zinc takes an important part as component of insulin and is also responsible for immunological processes. The common recommendation for piglets is 50 - 100 ppm/kg compound feed. The native content in vegetable feed stuffs is 30 - 40 ppm/kg. As supplementation Zink can be added in inorganic or organic bounded form. In EU the maximum permitted level in feed is 150 ppm/kg. Due to the ban of antibiotic growth promoters, especially in Scandinavia, there was a trend for using Zinc oxide in high dosages. These, by the feed law not allowed dosages of 2. - 3.000 ppm/kg feed, have positive effects on the gut wall, on the intestinal micro flora, on the gut associated immune system and on reducing of diarrhoea problems. Latest studies have shown that the usage of a special formulated Zinc oxide (Zinteral) produced comparably positive effects on health status of weaning piglets as the usage of high Zinc oxide levels.
