Antibiotics have been prohibited in livestock farming due to their link to the development of microbial resistance. The recent ban on antibiotics in poultry has underscored the urgent need for alternative methods to enhance growth performance in chickens. Various innovative strategies are being explored to address this challenge. Aspirin, known chemically as acetylsalicylic acid, has garnered attention in poultry nutrition, particularly in broiler diets. Its potential benefits include enhancing growth performance, improving feed efficiency, and possibly providing anti-inflammatory effects. This review synthesizes recent findings on the impacts of aspirin usage in broiler rations, focusing on growth and development, carcass traits, and health criteria. review of the literature indicates that the addition of aspirin to drinking water at concentrations exceeding 200 mg/L negatively impacts broiler performance and organ histology. Conversely, incorporating aspirin into the diet has been shown to significantly enhance performance and shift intestinal microflora from harmful to beneficial types. These effects are especially pronounced under stressful conditions commonly faced in broiler production, such as high stocking densities and heat stress. This review underscores the health advantages and potential uses of aspirin and its derivatives in broiler nutrition.
