摘      要：Two experiments were conducted to determine the nitrogen-corrected apparent metabolizable energy(AMEn) of differently processed meals from Juncea(Brassica juncea), yellow and black seeded canola(Brassica napus), with or without supplementation of multi-carbohydrase enzymes(Enz) in diets for broiler chickens. The first experiment was a 3×2×2 factorial arrangement with the main factors being seed type(yellow [Yellow] or black [B1] canola seeds and Juncea seeds), processed at two temperatures(high temperature desolventized-toasted [HTDT] at 95℃ or low temperature desolventized-toasted[LTDT] at 57℃), with or without Enz. In Exp. 1, a total of 384 one-day-old male broiler chicks were randomly assigned to 64 battery cages, with 6 birds/cage. The second experiment was a 2×2×2 factorial arrangement with the main factors being seed type(Yellow or black [B2]), seed source(Scott,Saskatchewan or Truro, Nova Scotia) and Enz(with or without) supplementation. A total of 264 one-dayold male broiler chicks were randomly assigned to 44 battery cages, with 6 birds per cage. In Exp, 1 and 2,all birds were fed a common starter diet from 1 to 14 days of age. From d 15 to 21, the birds were fed one of the test treatments, a basal grower diet or the basal grower diet replaced with 30% test ingredient with celite(0.8%) added as an inert marker. Excreta was collected on d 20 and 21. In Exp. 1, there were no interactions(P 0.05) among seed type, processing temperature and Enz. Processing temperature and dietary Enz did not affect(P 0.05) AMEn of different canola meals. The AMEn of prepress solvent extracted canola and juncea meals(PSEM) from Yellow(11.2 MJ/kg) was higher(P 0.05) among seed color,location and Enz. Supplementation of dietary Enz did not affect(P 0.05) AMEn of different cold press canola meals. The AMEn of cold press canola meals(CPM) from Yellow(14.7 MJ/kg) was higher(P 0.05)co
