Abstract: The studies on wild soybean were mainly concentrated in the development and utilization of its genes. Only a few studies were about its feeding value and the majority was mainly concentrated in the nutrients and feeding value of wild soybean seeds. And few studies were about the feeding value of whole-plant wild soybean. 22 samples of wild soybean were collected from 22 cities （counties）of Anhui Province to plant in the semi-wild environment. The main nutritional components and cutting value of whole-plant wild soybean were analyzed. The results showed that wild soybean had higher protein content, comparable to that of feeding alfalfa powder. Wild soybean had higher biology yield and good drought resistance, which was a kind of excellent forage resources.
