Abstract
International development organisations have improved billions of human lives in the Global South. However, in both their projects and advice to governments, most of these organisations neglect animal welfare. This blindspot matters. Poor welfare standards risk the organisation's reputation, particularly with donors; they reduce livestock lifespans and productivity, harming recipients; and they cause animals unnecessary pain and suffering. Here, we set out animal welfare guidelines for international development organisations. They were developed through extensive stakeholder engagement with organisations, donors, and recipients, especially in Africa. To comprehensively cover animal welfare, the guidelines encompass governance structure within the organisation, staff training, standard operating procedures, water, food, housing, social isolation, enrichment, drainage and waste disposal, disease, invasive procedures, transport, slaughter, breeds, record-keeping, and monitoring and evaluation of success. We urge international development organisations to adopt and institutionalise these guidelines, so they promote good animal welfare.
