The crude protein, crude fiber, calcium and phosphorus and 17 amino acids in the leaf meal of Broussonetia papyrifera were measured. The protein nutritional value was expressed as essential amino acid score and index. The feeding value was evaluated by the fuzzy optimum decision method. The results showed that B. papyrifera leaf meal was a protein feed which contains 23.62% crude protein and 20.95% seventeen amino acids. The ratio of E/T and E/N were 0.44 and 0.80, which were higher than the reference of 0.40 and 0.6 provided by FAO / WHO, respectively. Amino acid score of B. papyrifera was 50, which was lower than the leaf meal of tetraploid black locust, powder of pine needle and alfalfa meal. The essential amino acid index of B. papyrifera was 95.24, which was equal to that of above control feeds. The fuzzy optimum decision analysis showed that the leaf meal of B. papyrifera has a greater feeding value than alfalfa meal and the powder of pine needle, but its value was lower than tetraploid black locust meal.%研究测定了杂交枸树Broussonetia papyrifera叶粉的粗蛋白、粗纤维、钙、磷等常规营养成分的含量以及17种氨基酸组分.并运用必需氨基酸评分、必需氨基酸指数评价枸树叶粉蛋白质营养价值.用模糊最优局势决策分析法评价其饲用价值.结果表明,杂交枸树叶粉的粗蛋白和17种氨基酸含量分别是23.62%和20.95%,属于蛋白质饲料;必需氨基酸/氨基酸(E/T)为 0.44,必需氨基酸/非必需氨基酸(E/N)为0.80,高于FAO/WHO提出的E/T 应为0.40、E/N应在 0.6以上的参考蛋白模式;氨基酸分是50,低于四倍体刺槐叶粉、松针粉、苜蓿草粉;必需氨基酸指数95.24,与上述饲料比较接近.模糊最优局势决策分析结果是,杂交枸树叶粉饲用价值高于苜蓿草粉和松针粉,低于四倍体刺槐叶粉.
