Rational use of antibiotics in poultry production

Currently, in the USA, the European Union –E.U.–, Australia, Canada, Japan, and many other countries, the use of antibiotics of medical importance to improve the production parameters of flocks is prohibited or severely restricted. Consequently, the use of medically important antibiotics in these countries is only approved for preventing, controlling, or treating bird diseases.

Prevention / Prophylaxis

The administration of an antimicrobial to a group of animals of which none exhibit clinical signs of disease or diagnostic evidence of infection, when the transmission of existing but undiagnosed infections or the introduction of pathogens is anticipated based on history, clinical judgment, or epidemiological knowledge.

Control / Metaphylaxis

Control is the use of antimicrobials to reduce the incidence of infectious disease in a population with some animals exhibiting clinical signs of disease or already having diagnostic evidence of being infected.

Treatment / Therapeutic

This use assumes that animals with evidence of being sick can be distinguished and segregated from those healthy or without diagnostic evidence of infection to be treated; however, it is not feasible in species such as:

• Chickens or turkeys for fattening
• Laying hens
• Breeding hens

It is essential to define each of the uses of antibiotics in the practice of population veterinary medicine. Therefore, AVMA has recently proposed a series of definitions.

Currently, programs sponsored by the WHO, the OIE, and many government agencies in each country are being initiated for the responsible use of antibiotics in human and veterinary medicines to preserve the effectiveness of these essential tools to maintain human and animal health.

Medical-veterinary organizations such as the AVMA and specialty groups in the different species, such as the American Association of Avian Pathologists -AAAP- have developed their basic principles of reasonable and responsible use of antibiotics. For example, in poultry farming, the AAAP developed, in collaboration with the AVMA, the following basic principles for the rational and responsible use of antibiotics in
