Evaluation of multi-functional fodder tree and shrub species in mid-altitudes of South Omo Zone, Southern Ethiopia

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.
