Fitogênicos como substitutos aos antibióticos promotores de crescimento na nutrição animal

Abstract

Industrial poultry and swine production has advanced significantly in recent decades, driven by genetic and nutritional improvements. However, the indiscriminate use of antibiotic growth promoters (AGPs) has created selection pressure on microorganisms, resulting in the spread of antimicrobial resistance (AMR), a critical global public health issue. This study aims to review, through a bibliographic survey, the use of phytogenic additives as a strategic alternative to AGPs in animal feed. Phytogenics, bioactive compounds derived from plants, exert multifactorial effects that include antimicrobial, antioxidant, immunomodulatory, and digestion-stimulating actions. Comparative studies demonstrate that the use of essential oils and plant extracts can replace traditional promoters such as sodium monensin, maintaining or surpassing satisfactory zootechnical performance in animals. It is concluded that phytogenic additives are promising natural alternatives, capable of favoring intestinal integrity and the sustainability of production systems, aligning with national and international regulatory requirements.
