Abstract: The nutritional components of 21 kinds of common leguminous forage plants sampled from field survey were determined and statistically analyzed. Results showed that the tested leguminous forage plants had abundant nutrition. The average crude protein content reached up to 18.46%; the relatively lower crude protein content was observed in Glycine soja （10.75%） and Lespedeza bicolor （9.81%）; the relatively higher crude protein content was found in Trifolium repens （27.14%） and Robinia pseudoacacia （27.67%） （P〈0.05）. The average crude fat content was 2.58%; the relatively lower crude fat content was observed in Pueraria Iobata （ 1.73% ）, Vicia sepium （ 1.55% ）, and A lbiziajulibrissin （ 1.35% ）; the relatively higher crude fat content was found in Sophoraxanthantha （4.12%） and Glycine soja （4.14%） （P〈0.05）. The average crude fiber content was 25.04%; the lowest crude fiber content was observed in tender leaves of Pterolobium punctatum （10.51%） （P〈0.05）; the relatively higher crude fiber content was found in Lespedeza bicolor （35.79%） and Desmodium sequax （38.00%）. The average crude ash content was 7.43%; the relatively lower crude ash content was observed in Campylotropis macrocarpa （4.79%） and Pterolobium punctatum （4.77%）; the relatively higher crude ash content was found in Trifolium repens （10.09%）, Sophora xanthantha （10.18%）, and Lotus corniculatus （10.34%）. The average calcium content was 1.87%; the relatively lower calcium content was observed in Campylotropis macrocarpa （1.17%）, Cercis chinensis （1.10%）, andAmorphafruticosa （1.04%） （P〈0.05）; the relatively higher calcium content was found in Lespedeza bicolor （2.57%）, Medicago sativa （2.60%）, Sophora xanthantha （2.63%）, and Indigofera amblyantha （2.79%）. The average phosphorus content was 0.34%, the relatively higher calcium content was observed in Bauhinia brachycarpa （0.82%） and Sophora xanthantha （1.38%） （P〈0.05）. The leguminous forage plants in Guizhou mainly comprise of perennial shrub and herbage.
