Abstract
An experiment with 495 one-day-old male broiler chicks was conducted to investigate the effects of different dietary levels of canola meal (0, 10, 20%) and copper (0, 125, 250 mg/kg) on performance, carcass characteristics and some blood parameters. A completely randomized design with 3×3 factorial arrangement was used with 5 replicates from 1 to 42 of age. Feed intake was not significantly affected by treatments during 1 to 21 d, 21 to 42 d and throughout the study (P>0.05). The body weight gain and feed conversion ratio was significantly impaired (P0.05) by dietary treatments. An added level of 20% canola meal was significantly reduced plasma zinc concentration. Levels of copper supplementation increased (P
