¹Data are given as treatment means; n = 7 pens.

²Calculated composition: P-, 4.1 g P/kg DM; P+, 6.9 g P/kg DM; Ca-, 6.2 g Ca/kg DM: Ca+, 10.3 g Ca/kg DM; Phy-, 0 FTU/kg; Phy+, 1,500 FTU/kg as fed.

³ P-values are indicated as follows: n.s., P ≥ 0.10; †, P < 0.10; *, P < 0.05; **, P < 0.01; ***, P < 0.001.

^a–fMeans within a row not showing a common superscript differ (P < 0.05).
