Objective: To carry out a review to know the modes of action and the commercial application of unconventional plants as growth promoters in broiler chicken production.
Design / Methodology/Approach: A bibliographic review of unconventional and commonly used plants was carried out, which have shown efficacy as growth promoters on broiler chickens.
Results: Numerous reports have demonstrated the efficacy of phytochemicals present in plants as antioxidants, antimicrobials, and immune-stimulants.
Limitations of the study / Implications: Alternative use of unconventional plants can help to develop sustainable production systems and the production of innocuous meat products.
Findings / Conclusions: The use of additives of natural origin in poultry feed represents a viable option to replace or reduce the use of antibiotics and growth promoters on broiler chickens.
