中文摘要:
      枸杞叶是茄科枸杞属植物枸杞的茎叶,其活性成分和营养成分种类与枸杞子基本相同,具有较高的药用价值和营养价值。本文测定了枸杞叶草粉干物质、粗灰分、粗纤维、粗蛋白、粗脂肪、钙、总磷的含量,并与部分能量饲料、蛋白饲料和苜蓿草粉相应含量进行比较分析,研究其营养价值。结果表明:枸杞叶草粉干物质含量为90.98%,粗蛋白32.32%,粗脂肪1.10%,粗纤维7.8%,无氮浸出物34.76%,粗灰分15%,钙2.16%,总磷0.43%。其干物质含量高于能量饲料、蛋白饲料和苜蓿草粉,粗蛋白高于能量饲料和苜蓿草粉,粗脂肪低于三者,粗纤维含量介于蛋白饲料之间,无氮浸出物与蛋白饲料和苜蓿草粉相当,粗灰分和钙高于三者,总磷介于三者之间。综上所述,枸杞叶草粉具有较高的营养价值。
英文摘要:
      Lycium leaves are the leaves of Lycium Chinese Mill, the kinds of bioactive substances and nutrients in Lycium leaves are similar to Lycium barbarum. So it has high medicinal value and nutritional value. The contents of dry matter, crude ash, crude fiber, crude protein, crude fat, calcium and total phosphorus were determined in this paper, and compare them with corresponding contents of several energy feed, protein Feed, alfalfa meal to study its nutritional value. The results showed that the content of dry matter in Lycium leaves meal is 90.98%, the contents of crude protein, crude fat, crude fiber, nitrogen-free extract, crude ash, calcium and total phosphorus are 32.32%, 1.1%, 7.8%, 34.76%, 15%, 2.16%, 0.43% respectively. Its percentage of dry matter is higher than energy feed, protein Feed, alfalfa meal; crude protein content is higher than energy feed and alfalfa meal; crude fat content is lower than all the three feed; crude fiber content is among several protein feed; nitrogen-free extract content is as much as protein feed and alfalfa meal; crude ash content, calcium content are higher than the three feed; total phosphorus content is among the three feed. We can conclude from the above that ycium leaves meal has higher nutritional value.
