The broilers were fed: 1) a corn-soybean basal diet (Control); 2) the basal diet plus 15% of L. digitata (LA); 3) the basal diet plus 15% of L. digitata supplemented with 0.005% of Rovabio® Excel AP (LAR); and 4) the basal diet plus 15% of L. digitata supplemented with 0.01% of recombinant CAZyme (LAE)
