NC, negative control; PC, positive control. NC formulated without Pi and reduced in ME (−68 kcal/kg), crude protein (−10 g/kg), select AA (digestible Lys, Met and Cys, Thr, Arg, Val, and Ile, −0.1 to −0.4 g/kg; Table 1), Ca (−2.0 g/kg), digestible P (−2.2 g/kg), and sodium (−0.4 g/kg).
SEM, pooled standard error of the mean.
Excluding PC from the analysis.
Mean values in the same column bearing different superscript letters are significantly different at P < 0.05.
