This review analyzes how antimicrobial peptides enhance egg quality and animal health in laying hens, indicating a potential alternative to antibiotics.
Microbial resistance is a global concern, potentially causing 10 million deaths by 2050 due to the ineffectiveness of conventional drugs. In this scenario, antimicrobial peptides (AMPs) emerge as a promising alternative, as they combat several pathogens without inducing resistance. AMPs stand out as a potential natural additive to replace antibiotics in laying hens, such as gentamicin and tetracycline, aiming for greater animal health. Therefore, this review aims to provide a general overview of layer poultry farming worldwide, especially in Brazil. Furthermore, the study brings data on the interaction of parameters of egg quality and blood cells and how AMPs can be beneficial and improve the laying hens' health.
