| Two metabolism assays were carried out to determine corn and soybean meal metabolizable energy when enzymes were added. In the first trial, 35 cockerels per studied feedstuff (corn and soybean meal) were distributed in a completely randomized experimental design with four treatments of seven replicates of one bird each. The evaluated treatments were: ingredient (corn and soybean meal) with no enzyme addition, with the addition of an enzyme complex (xylanase, amylase, protease - XAP), xylanase, or phytase. Precise feeding method was used to determine true metabolizable energy corrected for nitrogen balance (TMEn). The use of enzymes did not result in any differences (p>0.05) in soybean meal TMEn, but phytase improved corn TMEn in 2.3% (p=0.004). In the... |
