Therefore, the objective of this revision is to acknowledge the importance probiotics have as an alternative for antibiotics as growth promoters in animals, based on several studies performed in farm animals. For this, a history journey since the moment antibiotics have been used as additions to animal feeding and its consequences on the generation of multi-resistant to antibiotics bacterial strains has been made, plus a follow up to their residual effect on food, until the banning of the use of such antibiotics in the European Union, in 2006.esCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráProbióticosAntibióticosAntibióticos en la nutrición animalAntibióticos como promotores de crecimiento (APC)Nutrición animalCrecimiento (animales)Article
