摘　　要：秋季沙枣成熟时,新疆各地摘取沙枣果枝,以果枝整体或果汁中分离的果实和叶子为原料,对其营养成分分析和消化性研究。沙枣干燥果枝整体、果实和叶子含粗蛋白(CP)分别为8.36%、6.87%、14.49%.果实的可溶性糖含量高达19.07%.叶子的酸性洗涤纤维(NDF)含量为33.35%。果枝整体、果实和叶子的体外干物质消化率分别为68.72%、69.03%、75.20%,可见沙枣的果实和叶子都具较高的营养价值,可作饲料开发利用。Fruit and twigs from Elaeagnus angustifolia were collected in the autumn from different areas Xinjiang and all twigs , fruits and leaves were analyed to evulate the nutrient components and digestibility. The fruit is rich in soluble sugars, while the leaves are rich in crude protein. Crude protein content of all twigs, fruits and leaves were 8.36%, 6.87% and 14.49% in the dry mater based, respectively. Soluble sugar in fruits is up to 19.07%, and the cellulose content of all fruiting twigs is not very high. The dry matter digestibility of all fruiting twigs, fruits and leaves was 68.72% ,69.03% ,75.20%, respectively. These results showed that The fruit and leaves from Elaeagnus angustifolia had higher nutritional value, can be used as feedstuff.
