title: The availability of fluoride from NaF and phosphorus supplements.
abstract: The availability of fluoride (F) from dicalcium phosphate (DCP), defluorinated phosphate (DFP), and raw rock phosphate (RRP) has been assessed and compared to the availability of F as NaF. Diets containing 50-55 ppm F were fed to lambs and rats and skeletal F retention determined. The relative availability of F in the different phosphate sources measured by this technique compared to that of NaF was about 50% (DCP), 20% (DFP), and 65% (RRP). Digestibility of F in goats fed similar diets was determined in a 4 x 4 Latin Square design experiment and found to be 38% (DCP), 34% (DFP), 65% (RRP), and 75% (NaF).
