1) Most rural households in sub-Saharan Africa keep livestock, but not all livestock keepers consume animal source foods (ASFs). While livestock ownership plays an important economic role, it does not necessarily predict higher ASF consumption. 2) Ownership of dairy cattle and poultry determine milk and egg consumption, but quantities consumed are generally negligible compared to daily protein requirements. Meat consumption averages just 2-14 kg per capita annually. 3) Increases in smallholder livestock productivity could improve livelihoods but are unlikely to significantly or directly impact nutrition on their own. Market mechanisms may be better than self-consumption for achieving adequate ASF protein and micronutrients. Targeting relatively large, market-oriented
