Effect Of Diet Complexity And The Additive Effect Of Pharmacological Levels Of Zno And Carbadox On The Performance Of Weaned Pigs, D.Y. Lee, G.W. Libal, C.R. Hamilton, D.N. Peters
South Dakota Swine Research Report, 2001
The scientific literature documents the efficacy of antibacterial feed additives for weaned pigs. More recently, Feeding therapeutic levels of supplemental zinc (Zn) from zinc oxide (ZnO) stimulated voluntary feed intake and weight gain of young pigs. Over the last decade, research demonstrated that swine diets contianing sub-therapeutic levels of various antibiotics combined with pharmacological levels of copper (Cu) resulted in better performance than when either ingredient was provided individually. In 1982, an additive improvement in performance was found when a sub-therapeutic level (55 mg/kg) of carbodox (CARB) and high level of Cu (125 mg/kg) were provided in combination in a …

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 …
Effects Of 2000 Mg/Kg Zn From Zno Or Carbadox On Performance Of Weaned Pigs As Influenced By Complexity Of Diets, G.W. Libal, T.A. Meyer
Effects Of 2000 Mg/Kg Zn From Zno Or Carbadox On Performance Of Weaned Pigs As Influenced By Complexity Of Diets, G.W. Libal, T.A. Meyer
South Dakota Swine Research Report, 2001
The positive effect of pharmacological levels of zinc (Zn) from zinc oxide (ZnO), is well documented. Zinc at 3000 mg/kg has been shown to be as effective as carbadox (CARB) in the weaned pigs’ diet. Recent research has demonstrated an unexpected effect on weaned pig performance from adding 3000 mg/kg of Zn from ZnO to simple diets. Normally, pigs fed complex diets with specialty ingredients outperform pigs fed simple diets, primarily because of increased feed intake. However, performance of pigs fed simple diets with added ZnO has been equal to performance of pigs fed complex diets with or without added …
