摘　　要：[目的]探究竹柳叶的饲用价值,以丰富优质饲料来源,促进畜牧业节粮绿色健康发展。[方法]测定竹柳叶的粗蛋白(CP)、粗脂肪(EE)、粗灰分(Ash)、粗纤维(CF)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)和无氮浸出物(NFE)含量,计算相对饲喂价值(RFV),并与其他6种粗饲料(青贮玉米、小黑麦、紫花苜蓿、桑叶、构树、辣木)进行比较,以研究其饲料化利用价值。[结果]竹柳叶的粗蛋白含量为16.33%,粗脂肪含量为2.26%,粗纤维、中性洗涤纤维、酸性洗涤纤维含量分别为8.98%、22.17%、14.87%,粗灰分含量为6.62%,无氮浸出物含量为51.00%。竹柳叶的营养成分中多项指标均优于青贮玉米、构树和小黑麦。从饲喂价值来看,竹柳叶RFV为324.41,高于其他6种粗饲料。[结论]竹柳叶具有较高的饲料化利用价值,可以将其开发为反刍动物饲料加以利用。[Objectives]The feeding value of leaves from bamboo and willow was studied to enrich the sources of feed with high-quality and promote the green and healthy development of food saving in animal husbandry.[Methods]The content of crude protein(CP),crude fat(EE),crude ash(Ash),crude fiber(CF),neutral detergent fiber(NDF),acidic detergent fiber(ADF),and nitrogen-free extract(NFE)in leaves of bamboo and willow were measured.The relative feeding value(RFV)of leaves from bamboo and willow was calculated and compared with that of other six types of roughage including silage corn,triticale,alfalfa,mulberry leaf,conformation tree,moringa oleifera to study the value of utilization as feed.[Results]The content of crude protein(CP),crude fat(EE),crude ash(Ash),crude fiber(CF),neutral detergent fiber(NDF),acidic detergent fiber(ADF),and nitrogen-free extract(NFE)in leaves of bamboo was 16.33%,2.26%,8.98%,22.17%,14.87%,6.62%,and 51.00%,respectively.The multiple indicators of nutritional components in leaves from bamboo and willow were superior to those in silage corn,triticale and conformation tree.The RFV of leaves from bamboo and willow was 324.41,higher than that of the other six types of roughage in terms of feeding value.[Conclusions]Leaves of bamboo and willow have high value of utilization as feed and can be developed as feed for ruminant animals.
