大熊猫饲粮氨基酸平衡的度量

Nutrition Evaluation of Amino Acids in the Rationing of Giant Panda

采用氨基酸比值系数评分 (SRC)法 ,对亚成体大熊猫两种配方饲粮的氨基酸营养价值进行了评价 .结果发现 :两种配方饲粮的 SRC得分分别为 84.6 0和 84.38,均能满足大熊猫对饲粮蛋白的需求 .另外 ,找出了两种配方饲粮的第一限制性氨基酸 (苏氨酸 )和第二限制性氨基酸 (缬氨酸 ) ,并计算出了各自的强化添加量 :A、B配方的苏氨酸强化添加量分别为 49.16、47.78mg/ (g pr) ;缬氨酸强化添加量分别为 6 5 .37、6 4.44 mg/ (g pr) .最后 ,探讨了进一步平衡饲粮氨基酸的 3种方案 .

Nutritional values of amino acids (AA) in two formulae of the giant panda rationing are studied using the SRC method. The SRC results of these formulae are 84.60 and 84.38, respectively, both meeting the protien demands of giant pandas. In addition, the first and second limitative AAs, referred to as VAL and LEN respectively, are found. The added amounts of enrichment for VAL are 49.16 mg/(g pr) and 47.78 mg/(g pr), and that for LEN are 65.37 mg/ (g pr) and 64.44 mg/(g pr), respectively. Finally, three schemes for AA balance are discussed.
