饲用苎麻营养物质动态变化规律及综合评价
|
摘要
对3种饲用苎麻(Boehmeria nivea L.)营养物质含量的动态变化进行了初步研究,并用灰色关联度法对供试的饲用苎麻营养价值进行了综合评定。结果表明,3种饲用苎麻粗蛋白、粗脂肪含量都随着收获茬次呈下降-上升-下降的趋势,总磷、HR001粗灰分含量呈上升-下降-上升趋势。HR002和中苎2号粗灰分含量呈下降-上升-下降-上升趋势。3种饲用苎麻钙含量和HR001、HR002粗纤维含量都随着收获茬数呈现出上升-下降-上升-下降趋势。6项评价指标权重大小依次为粗蛋白>粗灰分>粗纤维>钙>磷>粗脂肪。采用灰色关联度对饲用苎麻进行营养评价得到HR002饲用苎麻综合表现最优,HR001饲用苎麻次之,中苎2号最差的结果。
The dynamic changes of nutrients content in 3 kinds of forage ramie were preliminarily studied and the nutritional value of the feeding Ramie was evaluated by the grey correlation degree method. The results show ed that the content of crude protein and crude fat of 3 kinds of forage ramie was decreased-ascending-decreasing with the harvest stubble. The content of total phosphorus in 3 kinds of forage ramie and HR001 crude ash showed ascending-descending-ascending trend. The content of crude ash in HR002 and Zhongzhu No.2 showed a downward-rise-decline-rise trend. The CA content of 3 kinds of ramie and the content of HR001 and HR002 crude fiber showed a rise-decline-rise-decline trend with the number of harvesting stubble. The weights of 6 evaluation indexes were:crude protein,crude ash,crude fiber,calcium,phosphorus and coarse fat. Using the grey correlation degree to evaluate the nutritive value of the forage ramie,the overall performance of ramie HR002 was the best,the ramie HR001 was the second,and the Zhongzhu No.2 was the worst.
