Fig. 2. Sequential chemical fractionation of P forms in selected turkey and broiler litters. Selected litters include those from high and low non-phytate phosphorus (NPP) diets, and equivalent diets with and without phytase. Means followed by different letters are significantly different at the 0.05 probability level. The legend defines litters considered high and low in dietary NPP, with and without phytase as defined in Table 1.
