Duck-derived compound bacteria-fermented soybean meal improved laying performance and egg quality of laying ducks by modulating intestinal microbiota and health, antioxidant and immunological functions.

ABSTRACT: Fermentation of soybean meal has been shown to enhance duck performance. However, there are limited reports on the effects of duck-derived compound bacteria-fermented soybean meal (DFFB) on laying ducks. In this study, six strains of duck-derived bacteria were incorporated into compound fermented soybean meal, which significantly improved the quality of soybean meal by reducing pH and crude fiber content (P < 0.05), while increasing crude protein content (P < 0.05) and elevating levels of various unsaturated and saturated fatty acids (P < 0.05), alongside a reduction in certain trans fatty acids (P < 0.05). DFFB was used as an additive in the feed for 160 laying ducks, which significantly decreased the feed conversion ratio (FCR) and increased the Haugh unit of duck eggs (P < 0.05). Additi
