Nutritive Value of Expeller-Pressed Yellow Canola Meal for Broiler Chickens Following Enzyme Supplementation

Abstract

SUMMARY This experiment determined the effects of yellow expeller-pressed canola meal (Y-EPCM) residual oil (10 vs. 14%), meal heat treatment (+H: at 115°C for 25 min vs. –H: no heat treatment), and dietary enzyme (no enzyme, lipase, protease, carbohydrase) on the nitrogen-corrected apparent metabolizable energy (AMEn) value and amino acid (AA) digestibility for broilers. In total, 480 male day-old chicks were assigned to 16 dietary treatments (6 birds per cage, 5 replicate cages per treatment) in a completely randomized design in a 2 × 2 × 4 factorial arrangement from day 14 to 21, where residual oil, heat treatment, and enzyme were the main factors. All 3 factors in the experiment interacted to affect the AMEn, in which meals with 14% residual oil supplemented with carbohydrase had higher (P
