1Corn–soybean meal (SBM)-based basal diet of experiment 1 (Exp. 1.).
2Corn–SBM-based basal diet of experiment 2 (Exp. 2); analyzed concentration of nutrients in SBM, in % on dry matter (DM) basis: P, 0.75, Ca, 0.51; CP, 51.2; EE, 2.6; NDF, 17.3; ADF, 6.9; ADL, 0.6.
3Corn–SBM–rapeseed cake (RSC)-based basal diet of Exp. 2; analyzed concentration of nutrients of RSC, in % on DM basis: P, 1.24; Ca, 1.54; CP, 33.9; EE, 14.9; NDF, 23.0; ADF, 19.2; ADL, 6.8.
4Intrinsic plant phytase activity of basal diets was below the detection limit.
5Below the limit of quantification.
6Determined at pH 4.5 and 60 °C.
7Asp, Asn, and Glu, Gln, respectively, were detected together because the side groups of Asn and Gln are lost during acid hydrolysis (Fontaine, 2003).
