^aSources of double-low rapeseed meal are described in Table 1
^bValues for standardized ileal digestibility were calculated by correcting apparent ileal digestibility for the basal endogenous losses. Basal ieal endogenous were determined (g/kg dry matter intake) as crude protein, 15.2; Arg, 0.58; His, 0.16; Ile, 0.24; Leu, 0.50; Lys, 0.31; Met, 0.07; Phe, 0.26; Thr, 0.47; Trp, 0.10; Val, 0.37; Ala, 0.56; Asp, 0.62; Cys, 0.23; Glu, 0.74; Gly, 1.60; Pro, 4.61; Ser, 0.46; Tyr 0.46
