摘　　要：为了全面衡量银合欢的饲料价值,研究了12个银合欢品种叶片中的粗蛋白质、粗脂肪、粗纤维和粗灰分含量。结果表明,12个品种银合欢叶的粗蛋白含量都在25%以上,均为Ⅰ级,是理想的动物饲料;除了K376外,其他杂交新品种的粗蛋白含量都高于普通品种。由此可知,通过杂交能大大提高银合欢叶中粗蛋白含量,杂交银合欢粗脂肪含量大都高于普通品种,粗纤维和粗灰分含量与普通品种无明显差异。The results from analyzing the crude protein,crude fat,crude fiber and crude ash content in leaves of 12 Leucaena leucephala varieties for the purpose of measuring the feed value comprehensively showed that the crude protein content in leaves of Leucaena leucephala was above 25%,which indicates that the leaves of 12 tested Leucaena leucephala varieties all can be used as animal feed.The crude protein content in leaves of new hybrid Leucaena leucephala varieties is higher than common Leucaena leucephala varieties,except K376.Therefore,the crude protein content in leaves of Leucaena leucephala varieties can be greatly improved by cross breeding.The crude fat content of most hybrid Leucaena leucephala varieties is higher than common Leucaena leucephala varieties and there was no obvious difference in crude fiber and ash content between hybrid Leucaena leucephala varieties and common Leucaena leucephala varieties.
