宁夏不同产区、不同品种苜蓿的营养成分含量分析

Analysis of nutritional components of alfalfa from different producing areas and varieties in Ningxia

试验以宁夏银川、吴忠种植的苜蓿草捆为研究对象,进行营养成分分析和质量分级评定的研究。试验通过对粗蛋白质、粗脂肪、灰分、水分、酸性洗涤纤维、中性洗涤纤维、钙、磷8种营养成分含量进行测定,计算相对饲喂价值。以粗蛋白质含量和相对饲喂价值对苜蓿进行质量分级评定。结果表明,不同品种和不同产地苜蓿营养指标含量差异明显。

The experiment took alfalfa bales planted in Yinchuan and Wuzhong of Ningxia as the research object,carried on the nutrient composition analysis and the quality grading evaluation research.The relative feeding value was calculated through the determination of eight nutrient components of crude protein,crude fat,ash,moisture,acid detergent fiber,neutral detergent fiber,calcium and phosphorus.The quality of alfalfa was evaluated by crude protein content and relative feeding value.The results showed that the content of nutritional indicators in different varieties and habitats was significantly different..
