| 摘 要： | 用蛋白质自动定氮仪和Beckman-121MB型氨基酸分析仪测定红霉素药渣,粗蛋白质为18.38 %,10种必需氨基酸总含量为3.839 %,其中赖氨酸0.265 %、蛋+胱氨酸0.704 %、色氨酸0.347 %、苏氨酸0.213 %、亮氨酸0.690 %、缬氨酸0.343 %、异亮氨酸0.375 %、苯丙+酪氨酸0.400 %、组氨酸0.282 %、精氨酸0.220 %。真可利用蛋氨酸(0.53 %)与大豆饼(0.54 %)接近。以家禽理想蛋白质为模型计算必需氨基酸平衡指数(IEAA)是0.662～1.323,结合失衡度等指数的计算结果,证实红霉素药渣为家禽饲料的良好蛋白源。 |

| Abstract: | The crude protein (CP) and amino acid (AA) of erythromycin waste residue were determined with Beckman 121 MB-AA-analyzer. CP content (18.38 %) of erythromycin waste residue is close to CP supplementary feed.Ten EAA content amounts to 3.839 %, Lys. 0.265 %, Met+cys. 0.704 %, Trp. 0.347 %, Thr. 0.213 %, Leu. 0.690 %, Val. 0.343 %, Ile. 0.375 %, Phe+Tyr. 0.400 %, His. 0.282 % and Arg. 0.220 % respectively. True available Met (0.53 %) is equivalent to which of soybean cake (0.54 %). The index of essential amino acid balance (EAAI) were evaluated according to ideal protein of layers and broilers. The results showed that: the erythromycin waste residue is a kind of good protein source of poultry feed. |
