Abstract
About 70% of total phosphorus (P) and 60% of calcium (Ca) are bound to phytate in. wheat (Kim et al. 2002; Frolich and Asp, 1985), limiting the amount of P and Ca that is digestible in the gastrointestinal tract. The addition of Ca and P to pig diets is therefore required. Phytic acids are present in the aleurone layers of wheat, indicating non-starch a possible association of phytic acids with NSP-degrading polysaccharides (NSP) (Frolich and Asp, 1985) and supplements of phytase and enzyme may therefore increase P and Ca digestibility in weanling pigs fed, a wheat-based diet. The hypotheses tested were 1) wheat P-content will influence mineral digestibility; 2) individual supplementation of xylanase and phytase will increase P and Ca digestibilities; and 3) simultaneous supplementation of xylanase plus phytase will have synergistic effects on P and Ca digestibilities in weanling pigs fed wheats that differ in their P content.
