非淀粉多糖，例如β-葡聚糖和阿拉伯木聚糖，通常被认为是导致家禽大麦饲喂价值低的原因。然而，加拿大大麦中阿拉伯木聚糖的含量尚未得到彻底调查。测定了 1991 年加拿大西部大麦合作计划中种植的六棱（覆盖）、两棱（覆盖）和无壳（六棱和两棱）大麦 (Hordeum vulgare) 品种和基因型的总阿拉伯木聚糖、水提取物和酸提取物阿拉伯木聚糖水平。使用苔黑酚方法的二色修改进行分析。六棱大麦类型的阿拉伯木聚糖总量、水提取物和酸提取物浓度显着高于无壳或两棱大麦类型（P < 0.05）。无壳大麦中阿拉伯木聚糖的总含量（P < 0.01）、水提取物（P < 0.01）和酸提取物（P < 0.05）水平分别低于、高于和相似于二棱大麦样品中的阿拉伯木聚糖水平。环境对...
Non-starch polysaccharides, such as β-glucan and arabinoxylan, are often implicated as a cause of the poor feeding value of barley for poultry. Levels of arabinoxylan in Canadian barley types, though, have not been thoroughly investigated. Total, water-extract and acid-extract arabinoxylan levels were determined for six-rowed (covered), two-rowed (covered) and hulless (both six- and two-rowed) barley (Hordeum vulgare) cultivars and genotypes grown in the 1991 Western Canadian Barley Cooperative Program. Analyses were performed using a dichromatic modification of the orcinol method. The six-rowed barley types contained significantly greater total, water-extract and acid-extract arabinoxylan concentrations than hulless or two-rowed types (P < 0.05). In hulless barley, total (P < 0.01), water-extract (P < 0.01), and acid-extract (P < 0.05) levels of arabinoxylan were, respectively, less than, greater than and similar to levels of arabinoxylan in samples of two-rowed barley. Environment had a significant effe...
