用肉鸡和雏火鸡测定了黑籽甘蓝型、黄籽甘蓝型和油菜籽甘蓝型菜籽粕的营养价值。饲粮中黄籽甘蓝菌总氨基酸表观回肠消化率高于普通黑籽甘蓝菌和菜籽油品质甘蓝菌（88.8 vs 83.4和84.2%,P < 0.05）。用肉鸡测定黄籽甘蓝型和黑籽甘蓝型肉鸡的代谢能（AME(n)）含量分别为2190、1904和1736 kcal/kg DM。在火鸡试验中，黄籽和黑籽甘油三酯和菜籽油的AME(n)值平均分别为2166、2007和1877 kcal/kg DM。在肉仔鸡饲粮中添加多碳水酶可提高能量利用率（平均为1943 ~ 2249千卡/kg日增重），其中对芥子菜籽油的影响最为显著（1736 ~ 2356千卡/kg日增重）。
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. rapus 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).
