Feed resource challenges
Feed resource base in the highlands on a constant decline• Population pressure • Shrinking grazing lands• Land degradation and loss of soil fertility
Crop residues - constitute 20 – 80 % of feed resource• Implications on crop-livestock productivity, and
sustainability of the farming system Concerted effort needed to realize planned targets for the
livestock sub-sector under GTP II

Africa RISING feeds and forage action research
Approaches: Diagnostic and baseline surveys Innovation platforms (IPs) Research protocols based on the needs of communities Framers research groups (FRGs) around each protocol Evaluation and approval of research protocols by IPs Implementation through FRGs

Research protocols: I. Integration of fodder and soil
fertilizer trees in the farming system
Tree Lucerne: a leguminous fodder tree, well adapted to the highlands of Ethiopia: CP 17 – 21% In vitro DM digestibility ca. 70% More than 285 farmers participated in the action
research across eight kebeles

III. Postharvest handling and utilization of feed resources
Local feed storage and utilization practices incurs wastage of biomass and loss of quality
Improved feeding trough, storage shed and manual choppers introduced
Evaluated for their contribution and economic feasibility

Key lessons Forage interventions - key entry point Improved forage cultivation – not an option, but a necessity Farmers - willing more than ever to engage in forage
cultivation Adoption and utilization of improved forages is relatively
knowledge intensive: capacity building needs to be a core activity
Sustainable forage seed system - a priority issue Multidisciplinary and multi-sectoral approaches
![Page 19: Feed innovations for improved livestock productivity in the Ethiopian highlands: Africa RISING experiences](https://reader035.fdocuments.us/reader035/viewer/2022062522/588325671a28abe2758b6087/html5/thumbnails/19.jpg)
Ways forward: Africa RISING phase II Scaling of tested technologies to
more farmers and areas through development partners
Demonstrating other forage options on the menu
Creating strong partnership among all stakeholders
R4D to address emerging issues in the scaling process
