- Yeast enzyme hydrolysis slurry (YS) supplementation improves growth, intestinal health, and metabolic responses in juvenile largemouth bass.
- YS contains bioactive components like small-molecule peptides and amino acids, enhancing feed utilization efficiency.
- Study involved 320 largemouth bass divided into four groups with different diets: FM (control), SBM (soybean meal), and SBM with 1% and 2% YS.
- Results showed significant improvements in weight gain rate and specific growth rate in YS-supplemented groups.
- YS supplementation increased intestinal folds, goblet cell numbers, and digestive enzyme activities while reducing pathogenic bacteria.
- Metabolomics analysis revealed enriched protein digestion and amino acid metabolism pathways in YS-supplemented groups.
- YS improved antioxidant capacity, reduced intestinal permeability, and altered gut microbiota, contributing to better growth performance.
