南疆地区小花棘豆的营养成分分析

Analysis of nutrition of Oxytropis glabra in Southern Xinjiang

对新疆南疆地区小花棘豆Oxytropis glabra风干样的常规营养成分、主要矿物质元素及氨基酸含量进行测定,结果表明:小花棘豆干物质含量为94.49%、粗蛋白含量为14.97%、粗脂肪含量为3.11%、总能值为14 234 J/g、粗灰分含量为9.32%、中性洗涤纤维为36.70%、酸性洗涤纤维为28.06%、木质素为3.98%、纤维素为24.06%、钙0.98%、磷0.15%。小花棘豆中含有常见的17种氨基酸,其中包括9种必需氨基酸,氨基酸总量(占干质量)为13.42%,必需氨基酸总量为12.68%;微量元素含量与紫花苜蓿Medicago sativa的含量接近,是潜在的牧草资源。

The content of nutritional composition,mineral matter and amino acids of Oxytropis glabra in southern Xinjiang was determined.The results showed that dry matter in the plant was 94.49%,in which,crude protein content was 14.97%,3.11% crude fat,9.32% crude ash,36.70% neutral detergent fiber,28.07% acidum detergent fiber,3.98% lignin,24.06%,0.98% cellulose calcium,and 0.15% phosphonium.There was 17 kinds of amino acids,in which 9 kinds was essential.those amino acids accounts for 13.42% of dry weight,in which essential kinds was 12.68%.Trace element content was close to that in Medicago sativa.General energy was 14 234 J/g.Therefore,this plant has the potential to be used as a forage.
