摘　　要：随着我国畜牧业迅速发展,对优质粗饲料的需求日渐增加,使饲草的供应越来越紧缺,因而寻求可缓解传统饲料不足的新型饲料变得尤为重要。木本饲料是一种新型饲料,具有资源丰富、产量高、粗蛋白含量高等特点,合理开发利用可缓解我国畜多草少的压力。青贮可高质量保存和保全饲草营养养分,是木本饲料重要的贮藏方式。近年来,与木本饲料青贮相关的研究逐渐增多。本文总结了木本饲料营养特点及其影响因素、自然青贮发酵特性及其影响因素及木本饲料青贮在畜禽生产中的应用,并对后续研究方向做出建议,以期为木本饲料青贮利用和发展提供参考依据。With the rapid development of animal husbandry in China,the demand for high-quality roughage is growingly increasing,and the supply of forage is more and more scarce.Therefore,it is important to exploit new forage which can alleviate the shortage of traditional forage.Woody forage is a new type of forage that is characterized by abundant resources,high yield and high crude protein content.Reasonable development and utilization of woody forage may alleviate the shortage of forage resources.Silage is an important storage method of woody forage,which can preserve forage nutrients with high quality.In recent years,more and more researches have being focused on woody forage silages.This paper summarized the nutritional characteristics,quality of natural ensiling,improvement methods of woody forage silages,application of woody forage silages in livestock production and brought out suggestions for future research,aiming at providing reference for the utilization and development of woody forage silages.
