The document outlines initial ideas for the integrated core project on feeds and forages across four priority countries: Ethiopia, Tanzania, Uganda, and Vietnam, emphasizing tailored strategies for scaling and improving livestock productivity. Key findings highlight the importance of specific livestock types, potential interventions, and target populations in each country, while noting challenges such as the need for more diagnostic work and integration with other flagship initiatives. The CGIAR research program aims to enhance the sustainability and affordability of livestock systems, contributing to food security in the developing world.
