¹Control barley; ACD, chemically acidified barley; Fermented without phytase, fermented barley with L. reuteri; Fermented with phytase, fermented barley with L. reuteri and 500 FYT phytase/kg barley grain.

²The SID of CP and AA was calculated by correcting the AID of CP and AA with values for basal endogenous losses (g/kg DM intake; Jansman et al., 2002): CP, 10.53; Arg, 0.40; His, 0.16; Ile, 0.29; Leu, 0.44; Lys, 0.36; Met, 0.10; Phe, 0.31; Thr, 0.51; Trp, 0.13; Val, 0.41; Ala, 0.45; Asp, 0.70; Cys, 0.17; Glu, 0.85; Gly, 1.01; Pro, 1.31; Ser, 0.51; Tyr, 0.30.

³Least squares means based on 8 pig observations per diet.

⁴Acid, acid addition (Control vs. ACD); Fermentation, Control vs. Fermented without phytase; Phytase, fermentation with phytase (Fermented without phytase vs. Fermented with phytase).
