| Abstract: | 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 ((Landrace × Yorkshire) × Duroc)) 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 (Asp) and glycine (Gly) 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. |
