title: Energy values of canola meal, cottonseed meal, bakery meal, and peanut flour meal for broiler chickens determined using the regression method.
abstract: The energy values of canola meal (CM), cottonseed meal (CSM), bakery meal (BM), and peanut flour meal (PFM) for broiler chickens were determined in 2 experiments with Ross 708 broiler chickens from d 21 to 28 posthatch. The birds were fed a standard broiler starter diet from d 0 to 21 posthatch. In each experiment, 320 birds were grouped by weight into 8 blocks of 5 cages with 8 birds per cage and assigned to 5 diets. Each experiment used a corn-soybean meal reference diet and 4 test diets in which test ingredients partly replaced the energy sources in the reference diet. The test diets in Exp. 1 consisted of 125 g CM, 250 g CM, 100 g CSM, or 200 g CSM/kg. In Exp. 2, the test diets consisted of 200 g BM, 400 g BM, 100 g PFM, or 200 g PFM/kg. The ileal digestible energy (IDE), metabolizable energy (ME), and nitrogen-corrected metabolizable energy (MEn) of all the test ingredients were determined by the regression method. The DM of CM, CSM, BM and PFM were 883, 878, 878, and 964 g/kg, respectively and the respective gross energies (GE) were 4,143, 4,237, 4,060, and 5,783 kcal/kg DM. In Exp. 1, the IDE were 2,132 and 2,197 kcal/kg DM for CM and CSM, respectively. The ME were 2,286 and 2,568 kcal/kg DM for CM and CSM, respectively. The MEnwere 1,931 kcal/kg DM for CM and 2,078 kcal/ kg DM for CSM. In Exp. 2, IDE values were 3,412 kcal/kg DM for BM and 4,801 kcal/kg DM for PFM; ME values were 3,176 and 4,601 kcal/kg DM for BM and PFM, respectively, and the MEnvalues were 3,093 kcal/kg DM for BM and 4,112 kcal/kg DM for PFM. In conclusion, the current study showed that chickens can utilize a considerable amount of energy from these 4 ingredients, and also provided the energy values of CM, CSM, BM and PFM for broiler chickens.
