Livestock Emergency Guidelines and Standards (LEGS) is a set of international guidelines and standards for designing, implementation, and evaluating livestock interventions to help people affected by humanitarian crises. LEGS is based on three livelihoods objectives: to provide rapid assistance, to protect livestock assets, and to rebuild the livestock assets of crisis-affected communities.

LEGS supports the saving of both lives and livelihoods through two key strategies:

LEGS helps identify the most appropriate livestock interventions in emergencies,
LEGS provides standards, key actions, and guidance notes for these interventions based on good practice.
