Fig. 1From: Effects of calcium level and source, formic acid, and phytase on phytate degradation and the microbiota in the digestive tract of broiler chickensAverage daily gain (ADG), average daily feed intake (ADFI), and the gain to feed ratio (G:F) of broiler chickens fed with differently acidified diets with low and high Ca levels and without (−) or with (+) supplementation of 1500 FTU phytase/kg fed from day 16 of life to the end of the experiment on day 21 or 22 for half of the replicate pens of each treatment. 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 S1Back to article page
