Livestock contributes significantly to GDP in Eastern and Central African countries, ranging from 10-40% of GDP. A study identified milk as having the highest potential for growth and economic gains in the region. Investing in the livestock sub-sector could result in the second highest regional GDP gains after staples. However, production is not keeping up with demand growth due to population increase and diet changes. All ECA countries import milk and meat. Key opportunities exist to improve genetics, nutrition, veterinary services, and market access through standards harmonization and trade policy reforms to boost the livestock sector. Priority investments include research, production technologies, value addition infrastructure, market information systems, and an enabling policy environment.
