Apparent ileal digestibility (AID) of energy, dry matter, nitrogen and amino acids and standardized ileal digestibility (SID) of nitrogen and amino acids were evaluated in six weanling pigs fed unfermented soybean meal (SBM), yeast fermented soybean meal (SBMY), bacillus fermented soybean meal (SBMB), yeast and bacillus fermented soybean meal (SBMYB), canola meal (CM) and nitrogen-free diet. Pigs having body weights of about 17kg were surgically equipped with T-cannula and randomly allotted to one of five dietary treatments and a nitrogen-free diet in 6 × 6 Latin squares design of treatments. AID and SID of nitrogen was greater (P < 0.05) in SBMYB and SBMB treatments compared with SBM and CM treatment. AID and SID of the total essential amino acids were greater (P < 0.05) in SBMB and tended to be low in CM compared with SBM treatments. In this study, fermentation of soybean meal by Bacillus showed better digestibility of amino acid and nutrients.
