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 (( L andrace × Y orkshire) × D uroc)) fed unfermented soybean meal ( SM ), yeast fermented soybean meal ( SMY ), bacillus fermented soybean meal ( SMB ), yeast and bacillus fermented soybean meal ( SMYB ), canola meal ( CM ) and nitrogen‐free diet. Pigs having body weights 17.00 ± 0.3 kg were surgically equipped with T ‐cannulas of approximately 15 cm prior to the ileo‐cecal junction and randomly allotted to one of five dietary treatments and a nitrogen‐free diet in 6 × 6 Latin squares. AID and SID of nitrogen ( N ) was greater ( P < 0.05) in SMYB and SMB compared with SM and CM . AID and SID of amino acids such as, Lys (lysine) and Phe (phenylalanine) as well as total essential amino acids were greater ( P < 0.05) in SMB and tended to be low in CM compared with SM . AID and SID of aspartic acid ( A sp) and glycine ( G ly) tended to be higher in SMB compared with SM and other diets except CM . In conclusion, fermentation of soybean meal by Bacillus showed better digestibility of amino acid and nutrients.
