¹Data are the average of duplicate analyses of one sample with the exception that data for Ca and total P are the average of four separate samples that were analyzed in duplicate.

²Phytate was calculated by dividing the analyzed phytate P by 0.282 (Tran and Sauvant, 2004).

³Phytate P values were calculated from analyzed phytate P in the ingredients.

⁴Nonphytate P was calculated as the difference between total P and phytate P.
