Antibacterial agents in animal feed are essential for in the fight against pathogens and mitigating the effects of mycotoxins, both of which significantly impact livestock health and productivity. These agents inhibit harmful bacteria such as Salmonella and E. coli, reducing disease and preventing zoonotic risks. They also help maintain gut health, which is crucial for efficient nutrient absorption and growth, especially in young animals during vulnerable stag es like weaning. Additionally, antibacterial additives limit the growth of pathogens and support gut defenses against the combined effects of toxins and pathogens. By improving animal welfare, feed efficiency, and product safety, these additives play a key role in modern livestock production, though their use requires careful management to address concerns about antimicrobial resistance.
