Prececal (pc) Ca digestibility and amount of pc digested Ca of broiler chickens fed with differently acidified diets with low and high Ca levels without (−) and with (+) supplementation of 1500 FTU phytase/kg. Only significant (P < 0.050) effects are shown. Columns within a statistical comparison not sharing the same letter are significantly different (P ≤ 0.050). Details of the statistical evaluations are shown in Table S10
