刈青燕麦草全株及茎叶穗主要营养成分分析
|
摘要
为了评定刈青燕麦草的饲用价值和为新品种选育提供理论依据,文章采用高精度近红外快速分析技术对9个品种刈青燕麦草的茎、叶和穗3个部位进行了主要营养成分分析,结果显示:刈青燕麦草的茎、叶、穗中粗蛋白、酸性洗涤纤维、中性洗涤纤维、脂肪、水溶性碳水化合物含量存在着显著差异。叶中粗蛋白、脂肪平均含量最高,穗中水溶性碳水化合物平均含量最高,茎中酸性洗涤纤维和中性洗涤纤维平均含量最高。茎、叶、穗3个不同部位中叶和穗的营养价值最高,茎的营养价值最低。茎的干重在全株中所占比例仅次于穗,在选育饲草燕麦新品种时,应注重茎的品质选择。
This study was carried out in order to evaluate the feeding value of mowing oat grass and provide a theoretical basis for breeding new varieties.A high-precision near-infrared rapid analysis technique was used to analyze the main nutrients of the stems,leaves and spikes of nine varieties of mowing oats in this paper.The results showed that the highest were the crude protein and fat content of the leaves,the water-soluble carbohydrate content in spikes,and the acid detergent fibers and neutral detergent fibers in the stem of mowing oat.The leaves and spikes of the mowing oats have the highest nutritional value,and the stems have the lowest nutritional value.Therefore,we should pay attention to the proportion of stems,leaves and spikes in the whole plant when breeding new forage oat varieties.
