Fig. 2From: Effects of calcium level and source, formic acid, and phytase on phytate degradation and the microbiota in the digestive tract of broiler chickenspH in the crop, gizzard, and ileum of broiler chickens fed with differently acidified diets with low and high Ca levels and without (−) or 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 S2Back to article page
