Nutritional components or four kinds of perennial wild species or Arachis.L are analyzed, including main nutritional components (crude protein,crude fat,crude fiber),main mineral elements (Ca,P,K,Cu,Mn,Mo)and amino acid content. The results are showed as follows:the content of crude protein,calcium, phosphorus and essential amino acid is high,but crude fiber content is low,compared to other forage grass. For this reason,the perennial wild species or Arachis.L has a high feeding value as a graze.
