Fig. 8From: Effects of calcium level and source, formic acid, and phytase on phytate degradation and the microbiota in the digestive tract of broiler chickensPrececal (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 S10Back to article page
