Fig. 12.3. The phosphorus composition of broiler litter from a farm in Delaware, USA, determined by extraction with a solution containing sodium hydroxide and ethylenediaminetetraacetate (EDTA) and solution nuclear magnetic resonance spectroscopy. The extract contained 97% of the total phosphorus in the litter, of which 40% was phosphate and 60% was myo-inositol hexakisphosphate (phytic acid). Traces of pyrophosphate were also detected. The inset spectrum shows the four signals from myo-inositol hexakisphosphate, corresponding to the positions of the phosphates on the inositol ring (C-1 to C-6). Details of analytical methodology can be found in Turner (2004).
