The non-starch polysaccharides (NSP) content of maize, soybean meal (SBM), sunflower meal (SFM) and palm kernel meal (PKM) were analyzed. PKM followed by SFM had higher cellulose (22.3±0.05%, 15.8±0.06%), pentosan (18.6±0.03%, 9.3±0.03%) and total NSP (44.8±0.08%, 29.2±0.10%) content than SBM and maize. SBM contained more cellulose (4.2±0.02%) and total NSP (18.5±0.05%) and slightly less pentosan (4.4±0.04%) than maize (2.7±0.01%, 8.9±0.04% & 5.1±0.02%). Supplementation of any one of the tested commercial (A, B, C) and formulated (D, E) enzyme preparations to these feed ingredients released in vitro significantly (P<0.05) more total sugars than control. However supplementation of these enzyme preparations to maze-soy diet in commercial broilers (6 replicates of 8 broilers each per diet from 1-42 d age) did not the improve the performance in terms of weight gain, feed intake, feed/weight gain, livability, dressing yield, abdominal fat and weight of giblets.
