title: Content and distribution of different phosphorus forms in broiler chickens.
abstract: To understand the background value of phosphorus in chickens, the quantitative distribution of different phosphorus forms, including total phosphorus (TP), free phosphate (FP) and phospholipid (PL), in viscera, blood and bones of broiler chickens was investigated. Results showed that phosphorus contents exhibited significant differences in different parts of chickens. TP content of breast and thigh meat was over 5.0 g/kg, in which most of the phosphorus was in the form of water-soluble phosphates. TP content in viscera was higher than that in meat, and spleen was observed to contain the highest amount of phosphorus (10.0 g/kg). In all tested organs, FP and PL contents in liver were the highest, ranging between 1207-1989 and 81-369 mg/kg respectively. TP content in chicken bone was in the range of 52,716-136,643 mg/kg, and FP content in the bone was relatively lower than that in chicken meat.
