Abstract

Two experiments were conducted to determine the performance and ileal amino acid digestibility in growing male broilers fed diets containing solid-state fermented canola meal (SSFCM) and enzyme-supplemented canola meal (CM). In experiment 1 (performance trial), a total of 300-day-old Ross 308 male broiler chicks were allotted to six dietary treatments with five replicate pens of 10 birds each. Diet 1 was based on corn-soybean meal (SBM) as reference, diets 2 and 3 contained 300 g/kg CM and 300 g/kg SSFCM, respectively. Diet 4 contained 300 g/kg CM + phytase (PHY). Diet 5 contained 300 g/kg CM + xylanase (XYL). Diet 6 contained 300 g/kg CM + PHY + XYL. PHY at 500 FTU/kg and XYL at 1000 U/kg were added to the respective diets. During the experimental period (1 to 21 d), birds fed SBM and SSFCM diets recorded improved FI (p < 0.05). Broilers fed CM diet with enzyme supplementation had improved FCR compared to SSFCM diet. In experiment 2 (digestibility trial), a total of 240-twenty-one-day-old Ross 308 male broiler chicks were assigned to six dietary treatments with five replicate cages of eight birds each. Diet 1 was based on SBM, diets 2 and 3 contained 400 g/kg CM and 400 g/kg SSFCM, respectively. Diet 4 contained 400 g/kg CM + PHY. Diet 5 contained 400 g/kg CM + XYL. Diet 6 contained 400 g/kg CM + PHY + XYL. The inclusion of SSFCM and enzyme-supplemented CM in diets did not improve the apparent ileal digestibility (AID) of amino acids. The AID of calcium (Ca) was highest (p < 0.05) in SBM, CM and SSFCM. The AID of phosphorus (P) was increased (p < 0.05) in SBM and CM + PHY. Ca retention was higher (p < 0.05) in SSFCM and CM + PHY + XYL. Feeding SBM, SSFCM, CM + PHY and CM + PHY + XYL diets enhanced P retention. Further studies are required to establish the practical and nutritional implication of SSFCM on performance and ileal amino acid digestibility in broilers.
