The nutritive value of meals derived from black- and yellow-seeded Brassica napus and canola-quality Brassica juncea was determined with broiler chickens and young turkeys. A higher apparent ileal digestibility of total amino acids was observed in chickens fed diet containing yellow-seeded B. napus than in those fed conventional black-seeded B. napus or canola-quality B. juncea (88.8 vs 83.4 and 84.2%, P < 0.05). Metabolizable energy (AME(n)) contents for yellow- and black-seeded B. napus and B. juncea as determined with broiler chickens were 2190, 1904, and 1736 kcal/kg DM, respectively. In the turkey assay, the AME(n) values for yellow- and black-seeded B. napus and B. juncea canola averaged 2166, 2007, and 1877 kcal/kg DM, respectively. Multicarbohydrase enzyme addition to broiler chicken diets increased energy utilization (from 1943 to 2249 kcal/kg DM, on average), with the most pronounced effect observed for B. juncea canola (from 1736 to 2356 kcal/kg DM).
用肉鸡和火鸡来确定源自黑籽和黄籽油菜及油菜质量芥菜的膳食的营养价值。用含有黄籽油菜的饲料喂养的鸡比用传统黑籽油菜或油菜质量芥菜喂养的鸡表现出更高的总氨基酸表观回肠消化率（88.8%比 83.4%和 84.2%，P<0.05）。用肉鸡确定的黄籽和黑籽油菜及芥菜的代谢能（AME(n)）含量分别为 2190、1904 和 1736 千卡/千克 DM。在火鸡试验中，黄籽和黑籽油菜及芥菜油菜的 AME(n)值分别为 2166、2007 和 1877 千卡/千克 DM。在肉鸡饲料中添加多聚糖酶可提高能量利用率（平均从 1943 千卡/千克 DM 增加到 2249 千卡/千克 DM），对油菜质量芥菜的影响最为明显（从 1736 千卡/千克 DM 增加到 2356 千卡/千克 DM）。
