South Dakota Swine Research Report, 2001
Zinc (Zn) is an essential trace mineral for swine. The requirement for Zn has been suggested to be in the range of 50 to 100 mg/kg for pigs at various stages of growth. The bioavilability of zinc oxide (ZnO) as a source of Zn is lower than other Zn sources such as zinc sulfate (ZnSO4), zinc carbonate (ZnCO3) and Znmethionine in weanling pigs. Recent studies have shown that adding pharmacological levels (2000-4000 mg/kg) of Zn as ZnO to corn-soybean meal based diets improved started pig performance and was effective in controlling E. coli scours for weanling pigs. Very high levels …
