| 摘 要： | 测定了银合欢、大叶千斤拔、木豆和假木豆等4种常见热带灌木的主要营养成分和单宁含量及在舍饲条件下海南黑山羊对4种供试植物的采食量,采用饲料相对值RFV( Relative Feed Value)和粗饲料分级指数GI( Grading Index)对4种热带灌木的饲用品质进行了评定,并对干物质采食量与供试植物营养成分和单宁含量作了相关性分析.结果表明:2种评定体系分析表明,4种供试植物都有较高的饲用价值,且其在2种评定体系中的排序完全一致；海南黑山羊对热带灌木的采食量显著受到植物中干物质、粗灰分、酸性洗涤纤维、单宁含量的影响,海南黑山羊对干物质含量高且单宁含量低的植物有较高的采食量. |
| 关 键 词： | 热带灌木 采食量 单宁 饲用价值 |

| Abstract: | Intake of Hainan Black goats housed to four tropical shrub legumes,main nutritional and Tannins components were measured in this study.The RFV(Relative Feed Value) and GI(Grading Index) of four tropical shrub legumes fed were tested.Correlation coefficients between different factors were also analyzed based on the above measurement.The results showed that:(i)four shrub legumes showed high quality of feeding value,and showed the same quality order of the four forages evaluated by RFV and GI;(ii)Intake rate w... |
