Study on nutrient components of stem and leaf of Astragalus complanatus R.Brown
The aim of the experiment was to compare the nutrient content of the stem and leaf of Astragalus complanatus R.Brown at different sampling spots.The nutrients and mineral elements content of the stem and leaf of Astragalus complanatus R.Brown were determined according to the national method of nutrient composition determination of feed.The results showed that the dry matter content of the stem and leaf of Astragalus complanatus R.Brown was 88.82%～95.85%,the crude protein content was 9.91%～14.47%,the crude fiber content was 17.44%～25.89%,the crude fat content was 1.42%～4.98%,the crude ash content was 4.81%～12.41%,the non-nitrogen extract content was 43.35%～53.00%,the calcium content was 148.10～530.98 μg/g,the copper content was 0.60～7.17 μg/g,the iron content was 24.38～118.41 μg/g,the magnesium content was 29.04～34.27 μg/g,the manganese content was 2.48～6.97 μg/g,the potassium content was 102.21～2 306.46 μg/g,the sodium content was 19.42～88.92 μg/g,and the zinc content was 0.07～1.90 μg/g.The study indicates that the stem and leaf of Astragalus complanatus R.Brown are rich in nutrients and mineral elements and can be used as forage.Among them,the five samples from Chaganhu,Tao-nan Yongmao,Tongyu County,Baicheng Tao-bei District,and Qian'an Minzi village all reach the standard of leguminous forage and can be used as leguminous forage.
