摘　　要：测定了3个品种香蕉茎叶的营养成分及其单宁含量,并结合体外产气法测定了香蕉茎叶的体外干物质消化率和产气量。研究结果表明:香蕉茎叶干物质(DM)、粗蛋白质(CP)、粗脂肪(EE)、代谢能(ME)以及体外干物质消化率(IVDMD)和饲料相对值(RFV)较低,尤其是香蕉假茎,属于品质较差的粗饲料;香蕉茎叶中NDF、ADF、CP和Tannins含量共同影响产气量(GP)和IVDMD。Nutritional components and tannins content of 3 Banana Stems and Leaves were determined.The gas production（GP）,in vitro dry matter degradability（IVDMD） and metabolic energy（ME） of 3 Banana Stems and Leaves were determined by in vitro gas Production methods.The results indicated that： The low DM,CP,EE,ME,IVDMD and RFV make Banana Stems and Leaves a low feeding value fed for tropical livestock.GP and IVDMD had significant correlation with NDF、ADF、CP and Tannins.
