This study aimed to investigate the effects of fermented blueberry pomace (FBP) on the intestinal barrier function and cecal microbiome of aged laying hens. A total of 320 Yukou Jingfen No. 8 laying hens (345-day-old) were randomly divided into a control group, 0.25% FBP group, 0.5% FBP group, or 1.0% FBP group. The results showed that the villus height (VH) in the jejunum of the 0.25–0.5% FBP groups and villus surface area in the jejunum of the 0.25% FBP group were higher (p < 0.05), while 0.25% FBP supplementation displayed a higher (p = 0.070) VH in the ileum compared to the control group. Mucin-2 expression was upregulated (p < 0.05) in the jejunum of the 0.5% FBP group and the ileum of the 0.25–0.5% FBP groups. Compared to the control group, interleukin (IL)-4 and IL-13 expressions were upregulated (p < 0.05) in the 1.0% FBP group. Microbiota analysis revealed that Prevotella abundance in the cecum of the 0.5–1.0% FBP groups was higher (p < 0.05) than in the 0.25% FBP group. In addition, microbial function prediction analysis showed that cecal microbiota in the 0.25% FBP group were mainly enriched by alanine/aspartate/glutamate metabolism and methane metabolism. Moreover, Spearman’s correlation analysis revealed the potential correlations between the abundance of the cecal microbiota and intestinal-barrier-function-related gene expressions, as well as the short-chain fatty acid content, of laying hens. In summary, dietary FBP supplementation enhanced intestinal barrier function by improving intestinal morphology, upregulating gene expressions related to barrier function, and altering the cecal microbiota of aged laying hens.

Application of Natural Antioxidants from Fruits Waste for Improving Egg Quality Characteristics

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.
