Fruit waste poses a significant global challenge, with the Food and Agriculture Organization (FAO) reporting that about 1.3 billion tons of food is wasted annually, contributing to environmental and economic challenges. The major fruit-producing countries (United States, China, India, and Brazil) are responsible for a large portion of this waste. Fruit waste contains different bioactive compounds like polyphenols, flavonoids, vitamins, and carotenoids, which are, in large part, underutilized regardless of their antioxidant properties. These compounds can play an important function in poultry nutrition, offering natural alternatives to synthetic antioxidants. Reintegrating fruit waste into poultry diets might have potent benefits on the nutritional quality and shelf life of eggs. Some studies reported that bioactive compounds from fruit waste improve the oxidative stability of eggs and the nutritional content, potentially extending shelf life during storage. Additionally, antioxidant compounds from fruit waste have been shown to improve yolk coloration and some egg quality parameters while reducing reactive oxygen species, which cause lipid oxidation. Their inclusion in poultry diets can lower feed costs, promote animal welfare, and reduce the environmental impact of fruit waste. This review highlights some key fruit wastes, such as citrus, apple, grape, rosehip, sea buckthorn, and banana, among others, which are natural reservoirs of bioactive compounds beneficial for poultry nutrition. This strategy aligns with FAO sustainability goals, addressing both food waste and animal nutrition challenges. Future studies should focus on optimizing the inclusion rates of these natural antioxidants in poultry diets to maximize their benefits. |
