Broiler Farming in Africa vs. the EU: Divergent Systems, Shared Challenges, and Future Directions-A Review.

BACKGROUND: Broiler production systems in Africa and the European Union (EU) differ substantially in terms of housing design, environmental control, welfare outcomes, and regulatory oversight. Understanding these differences is essential for identifying region-appropriate strategies for sustainable poultry production. OBJECTIVES: This review aimed to compare broiler housing systems, welfare outcomes, environmental management, and regulatory frameworks in Africa and the EU. METHODS: This review followed some aspects of the PRISMA 2020 guidelines. Searches were conducted in Scopus, Web of Science, PubMed, and CAB Abstracts from January 2023 to January 2025. The grey literature from the FAO, EU institutions, and NGOs was also screened. Eligible studies examined broiler housing systems, welfare indicators, environmental control, or regulatory frameworks in African or EU contexts. Two reviewers independently screened records, extracted data, and assessed risk of bias using the SYRCLE tool. No meta-analysis was performed due to heterogeneity; results were synthesized narratively. RESULTS: The search identified 86 records; 83 remained after duplicate removal. After screening, 45 studies met the inclusion criteria. EU systems were characterized by climate-controlled indoor housing, strict welfare regulations, and integrated supply chains. African systems ranged from intensive open-sided houses to semi-intensive and backyard systems, with major constraints including heat stress, limited access to veterinary care, and high feed costs. These systems also differ markedly across African regions, reflecting variation in infrastructure, market integration, and climatic conditions. Risk of bias was moderate across most studies. The certainty of the evidence was low to moderate due to heterogeneity in study designs and reporting. LIMITATIONS: Heterogeneous study designs prevented quantitative synthesis. Reporting quality varied, and few African studies provided detailed welfare metrics. CONCLUSIONS: Broiler production systems in Africa and the EU reflect distinct climatic, economic, and institutional contexts. Sustainable improvements require region-specific strategies rather than universal housing models. In this review, region-specific strategies refer to climate-adaptive housing designs, modular environmental control technologies, and management approaches aligned with local infrastructure, market structures, and resource availability.
