摘要
以10个柱花草品种(品系)为试材,测定其营养成分及单宁含量,并结合体外产气法测定其体外干物质消化率和产气量。结果表明,饲料相对值RFV从大到小的排列顺序为:热研2号>TPRC90028>TPRC90089>热研18号>热研7号>热研10号>907>CIAT11362>热研5号>热研13号;柱花草具有粗蛋白含量、代谢能含量较高,中性洗涤纤维、酸性洗涤纤维含量适中,单宁含量低,体外干物质消化率较高等特点,是一种优良的热带豆科牧草。
Nutritional components and tannins content of 10 Stylosanthes spp.were determined.The gas production(GP),in vitro dry matter degradability(IVDMD) and metabolic energy(ME) of 10 Stylosanthes spp.were determined by in vitro gas production methods.The Relative Feed Value(RFV) of these forage were lined as this sequence from high to low: Reyan No.2,TPRC90028,TPRC90089,Reyan No.18,Reyan No.7,Reyan No.10,907,CIAT11362,Reyan No.5,Reyan No.13.The results indicated that: the high CP and ME,suitable NDF and ADF,low tannins content and high IVDMD make Stylosanthes spp.a high nutrient value tropical legumes forage for livestock
