250 Effect of Dietary Zinc and Copper Supplements on Digestibility of Minerals in Growing Pigs

Abstract Dietary zinc (Zn) and copper (Cu) supplementation can affect the digestion absorption of nutrients in pigs, especially minerals. This study aimed to evaluate effect dietary levels Zn Cu on their ileal (AID) total tract (ATTD) digestibility that manganese (Mn), calcium (Ca), phosphorus (P). Six crossbred pigs were surgically equipped with a single-T cannula distal ileum. In cross over design, received one four corn-soybean meal diets supplemented by two (100 500 mg/kg as oxide) (40 80 mg / kg sulfate) for each period (7d 2d digesta feces collection). this study, high level increased Mn AID (P< 0.01) but decreased Ca 0.05). The improved only when was used (Zn x Cu, P< 0.051). ATTD Zn, Mn, P greater receiving 0.01). also its reduced low added post-ileal showed significant (digestibility different from 0). confirmed could be affected growing pigs. ATTD. last result is contradictory must analysis phytic P.
