Pattern of antimicrobial usage in livestock animals in south-western Nigeria: The need for alternative plans.

Resistance to antibiotics has continued to increase, placing future animal and human disease management in real danger. The developing countries characterised by widespread indiscriminate antibiotic use and in which 'third-generation' antibiotics are not readily available or affordable are the worst affected. A 3-year (2010-2012) retrospective survey of antibiotic usage in livestock production in three selected states of south-western Nigeria was conducted.
