Yeast polysaccharides modulate lipid metabolism and restore oviduct inflammatory and microbial homeostasis to support egg quality in Salmonella Pullorum-challenged hens

Key Points

• The study aims to explore how yeast polysaccharides affect lipid metabolism and restore balance in the oviduct in hens challenged by Salmonella Pullorum.
• Evaluated the effects of yeast polysaccharides on lipid utilization and yolk pigmentation.
• Assessed changes in inflammation and microbial balance in the oviduct.
• Conducted trials using hens challenged with Salmonella Pullorum.
• Yeast polysaccharides improved lipid utilization and yolk pigmentation.
• Enhanced resistance of the oviduct-egg axis to Salmonella Pullorum was observed.
• Restoration of microbial homeostasis and reduction in inflammation were noted.
