| 摘 要： | 大麦体外消化试验结果揭示，添加NSP酶（GXC）使大麦中干物质、粗蛋白、粗灰分、无氮浸出物、粗脂肪和粗纤维的消化率分别提高了18．13％、20．27％、15．99％、16．42％、和26．93％和30．02％；大麦中各种氨基酸体外消化率显著提高，幅度为11．83％－61．39％；添加NSP酶使大麦胚乳细胞壁在体外完全降解；消化过滤液中葡萄糖和总氨基酸含量分别提高了17．58％和10．26％；而粘度降低了4．51％。

| Abstract: | The digestive experiment in vitro showed that supplement of NSP Enzyme (GXC) significantly increased the digestibility of DE, CP, CA, NND, EE and CF of barley respectively by 18.13% ,20.27% ,15.99% ,16.42% ,26. 93% and 30.02% ,inhanced the digestibility of AA by 11.83 - 61.39% .NSP Enzyme (GXC) made endosperm cell wall of barley degrade completely,increased glucose and amino acid in digestive solution filtrated by 17.58% and 10.26% respectively and decreased the filtrate viscosity by 4.51% . |
