Abstract

A study was conducted to evaluate the early growth performance and nutrient composition of some selected tree/shrub species in the fodder bank agroforestry system. Moringa stenopetala, Terminalia brownii, Morus alba, Melia azedarach, and Sesbania sesban were used for this study. Square quadrants of 16 m2 plot sizes were established with the RCBD of three replications. Seedlings were planted with 1 m × 1 m spacing between rows and plants respectively. The growth and chemical composition of the studied tree/shrub species were evaluated with one way ANOVA. The growth parameters and nutrient composition of the studied fodder tree/shrub species are significantly (P ≤ 0.05) varied. The nutrient composition of the studied tree/shrub species ranged between percentages of 88.3 - 90.6 of Dry Matter, 5.7 - 13 of Ash, 12.45 - 22.35 of Crude Protein, 11.8 – 23.5 of Acid Detergent Fiber and 18.1 - 33.6 of Neutral Detergent Fiber. S. sesban and M. stenopetala are the consistent and superior tree/shrub species with growth performance and nutrient content parameters respectively. In addition to this, the selected fodder tree/shrub species are well adapted in the fodder bank agroforestry system and have considerable nutrient constituents. Thus the studied tree species seems to be a potential alternative for complementing the basal feed. Key words: Fodder bank, livestock feed, South Omo, nutrient composition, agroforestry.

埃塞俄比亚南部南奥莫区中高海拔多功能饲料乔灌木树种评价

对饲料库农林复合系统中部分乔灌木树种的早期生长性能和养分组成进行了研究。以辣木、黄尾木、桑、苦楝和田菁为研究对象。用3个重复的RCBD建立16 m2样块大小的方形象限。幼苗行距和株距分别为1 m × 1 m。采用单因素方差分析对研究树种的生长和化学成分进行了评价。饲料乔灌木各树种的生长参数和营养成分差异显著(P≤0.05)。研究树种的营养成分为干物质88.3 ~ 90.6，灰分5.7 ~ 13%，粗蛋白质12.45 ~ 22.35，酸性洗涤纤维11.8 ~ 23.5，中性洗涤纤维18.1 ~ 33.6。在生长性能和养分含量参数上，豆瓣草和窄瓣草是一致和优越的乔灌木树种。此外，所选饲料乔灌木品种在饲料库农林复合系统中适应性较好，营养成分丰富。因此，所研究的树种似乎是补充基础饲料的潜在替代品。关键词:饲料库，家畜饲料，南奥莫，营养成分，农林复合。
