Finding environmentally friendly, effective and residue-free alternatives to antibiotics has become a research priority. This is due to the ban on antibiotics in animal feed. Curcumin is a polyphenol extracted from the rhizome of turmeric that has antioxidant, anti-inflammatory and immunomodulatory properties. Curcumin has been widely demonstrated as a traditional flavoured agent and herbal medicine in the fight against diseases. In recent years, curcumin has been extensively studied in animal production, especially in poultry production. This article reviews the source, structure, metabolism and biological functions of curcumin and focuses on the application of curcumin in poultry production. In terms of production performance, curcumin can improve the growth performance of poultry, increase the egg production rate of laying hens and alleviate the negative effects of heat stress on the production performance of poultry and livestock. In terms of meat quality, curcumin can improve poultry meat quality by regulating lipid metabolism and antioxidant capacity. In terms of health, curcumin can improve immunity. Since mycotoxins have been a major problem in poultry production, this article also reviews the role of curcumin in helping poultry resist toxins. It is hoped that the review in this article can provide a concrete theoretical basis and research ideas for the research and application of curcumin in the field of poultry.
