ISSUE FOCUS 34 FEED & ADDITIVE MAGAZINE January 2024 It has been almost 100 years since penicillin was discovered by Alexander Fleming. Since then, other antimicrobials and new applications other than medical treatment were developed. With that, also evolved the phenomenon antimicrobial resistance (AMR), in which bacteria experience structural or biochemical changes, becoming resistant to antimicrobials. The risk comes from the transmission of genes responsible for antimicrobial resistance from harmless bacteria to pathogen recipients. Then mitigating AMR became a global priority, with the European Union leading the ban of antibiotics used as growth promoters in 2006. Since then, antimicrobials can only be distributed by veterinarians for therapeutic treatment. Economical animal production will only be possible by adopting a holistic approach, enhancing intestinal resilience, supporting systemic immunity, and promoting proper biosecurity and management. PAST AND CURRENT STATUS OF ANTIMICROBIALS IN ANIMAL PRODUCTION According to the National Committee for Clinical Laboratory Standards of USA, in-feed antimicrobials have four applications to animal production: “In the dynamic world of livestock production, the increase of antimicrobial resistance and consumer demand for high-quality food has raised the interest for sustainable and ‘natural’ alternatives to AGPs to meet growth performance and feed efficiency expectations. Phytogenic compounds are on the frontline for their demonstrated benefits in this field. Moreover, phytogenic compounds supplemented at low inclusion rates have shown to be beneficial not by inhibiting pathogens, but by supporting the animal’s resilience to overcome them more effectively.” INTESTINAL HEALTH AND PATHOGEN RISK-REDUCTION BENEFITS ANTIMICROBIAL MANAGEMENT Célia G da Silva Global Product Specialist Bioactives ADM Dr. Luiz Souza Asia & Pacific Technical Sales Director Livestock ADM
