Resumo
Soon after their discovery, antibiotics and chemotherapy drugs used in veterinary
medicine for the treatment of diseases and bacteria were incorporated into animal
feed as growth promoters (AGPs). Thus, since the 1950s, antimicrobial agents and
chemotherapy have become an integral part of animal feed in large quantities, raising
concerns about the resistance of bacteria to those transmitted from animals to humans. Therefore, worldwide efforts have been promoted to achieve prudent use of
antibiotics in animal feed. Some of the criteria that constitute a prudent use of
antimicrobial agents from different production systems are still unstable. In particular,
the quantity and subtherapeutic use in routine use in animal feed to promote growth
has been a topic of discussion (AARESTRUP et al., 2010). The European Union has
decided to end the use of AGPs in early 2006 (DVFA, 2010), but this involves
damage to livestock, because studies indicate that simple withdrawal of antibiotic
growth promoters in the diet of birds leads to a decrease in the average performance
of 3% to 7% and the negative impact on animal health and increased mortality. Thus,
there is a need to introduce new strategies to circumvent these effects, and a widely
studied nutritional approach is the use of new food additives that are effective in
improving the performance of the birds, hypothetically through a modulation of
intestinal microbiota (LANGHOUT, 2005). Among the new food additives can
substitute for AGPs, have probiotics, prebiotics, synbiotics, extracts, oils, organic
acids, among others. This study was designed to do a review on the antimicrobial
and chemotherapeutic drugs used in poultry and their possible replacement by
alternative products.
