Abstract
Microbial fermented feed (MFF) has been demonstrated to improve nutritional status as well as promote animal health. However, only a few studies have focused on its effect on the flavor of animal products, and the potential underlying mechanisms remain poorly understood. Herein, egg amino acids and yolk trimethylamine (TMA), small intestine histomorphology, cecal microbiota and yolk metabolites were analyzed in MFF-treated ducks. The results showed that MFF significantly increased the flavor amino acids in duck eggs, along with reducing the yolk TMA. MFF caused an increase in beneficial cecal microflora, and regulated the bacteria involved in the metabolism of glucolipid, TMA and its N-oxide. Moreover, MFF regulated 34 annotated metabolites markedly enriched in four metabolic pathways. Correlation analysis showed that cecal microbiota and yolk metabolites were closely related to flavor-related indicators of duck eggs. Our study therefore provides a theoretical basis for improving avian egg flavor starting from the feed.
