Abstract
The objective of this study was to investigate the effect of processing conditions and chemical composition on ileal digestible energy (IDE), AME, and AMEn of 6 expeller-extracted canola meal (ECM) samples subjected to conditioning temperature at 90, 95, or 100°C and high or low screw torque over the second presses in a 3 x 2 factorial arrangement. The ECM samples were incorporated into a corn-soybean meal reference diet at 30% by replacing energy-yielding ingredients. A total of 210 one-day-old male broiler chicks (Ross 308) were fed common starter and grower diets until d 18, and then assigned to 7 experimental diets replicated 6 times, with 5 chicks per cage. After a 5-d diet acclimation period from d 18 to 22, excreta was collected for 72 h. The difference method was used to determine AME, which was corrected to zero N balance to obtain AMEn. Medium seed conditioning temperature resulted in the highest IDE, AME, and AMEn compared with low or high temperature, and high screw torque resulted in higher energy utilization compared with low torque (P < 0.001).
