Among them, the crude protein, crude fat, neutral detergent fiber, acid detergent fiber, P and Ca contents were treated as the judging indicators. The nutritional value evaluation was carried out with the analytic hierarchy process(AHP). The results showed A49(Guangxi)had the highest nutritional value. Its dry matter, crude protein, crude fat, crude ash,neutral detergent fiber, acid detergent fiber, Ca and P contents were 32.35%,7.20%, 4.06%, 8.07%, 75.81%, 50.72%, 0.23% and 0.16% respectively. While A3(Guangdong) had the lowest nutritional value. Its dry matter, crude protein, crude fat, crude ash, neutral detergent fiber, acid detergent fiber, Ca and P contents were32.24%, 4.62%, 0.51%, 6.38%, 46.40%, 40.02%, 0.15% and 0.09% respectively.The crude protein content differed significantly among different germplasms. A48 had the highest crude protein content(9.11%), and A14 had the lowest crude protein content(3.72%). Based on the evaluation results, the 43 Saccharum spontaneum L.germplasms were divided into 3 groups: high-nutritional value type, moderate-nutritional value type and low-nutritional value type. We hoped to provide a theoretical reference for the application of Saccharum spontaneum L. as a forage grass.展开更多
