摘　　要：对云南省主要豆科饲用灌木的营养成分含量进行分析,结果表明:在营养期、开花期、结荚期、种子成熟期(枯黄期)4个生育期,粗蛋白、粗脂肪、粗灰分、钙和磷的含量差异显著。除多花木兰、银合欢和假大青兰外,灌木各生育期的钙磷比基本都在草食家畜的耐受范围(7∶1),能够满足家畜的营养要求。The nutritional content of legume feeding shrubs in Yunnan Province was analysis. The results showed that the differences among crude protein, crude fat, crude ash, calcium and potassium during nutritional stage,flowering stage, pod bearing stage and withering stage were significant. The ratio of Ca and P of all shrubs could meet the nutritional requirement of livestock and the balance between Ca and P was appropriated （lower than 7： 1） for grazing livestock except Indigofera amblyantha ,Leucaena leucocephala and Indigofera galegoides.
