¹⁾

Values were determined using the pooled samples from eight replicate cages of 20 and 5 birds per cage for 10- and 21-d-old male broiler chickens.

^a,b

Least squares means within a row without a common superscript differ (p < 0.05).

DMI, dry matter intake; AA, amino acids; Arg, arginine; His, histidine; Ile, isoleucine; Leu, leucine; Lys, lysine; Met, methionine; Phe, phenylalanine; Thr, threonine; Val, valine; Ala, alanine; Asp, aspartic acid; Cys, cysteine; Glu, glutamic acid; Gly, glycine; Pro, proline; Ser, serine; Tyr, tyrosine.
