^a–d

Averages (Avg) with different superscripts within the same column differ (P < 0.05).

DM = dry matter.

Phytate P, calculated as 28.2% of phytate (Tran and Sauvant, 2004).

Nonphytate P, calculated as the difference between total P and phytate bound P.

⁴

ND, not detectable.

⁵

SEM = pooled standard error of the mean.

⁶

Not compared because mineral was not detectable in some ingredients.
