Diets containing hydrolyzed feather meal improved final weight by 2.18-fold compared to controls, enhancing growth in prawns.
Survival rates for prawns ranged from 73.3% to 83.3%, indicating no significant differences among different diet groups.
Inclusion levels of hydrolyzed feather meal above 3.0% promoted better growth metrics of length and biomass gain.
No negative effects on antioxidant biomarkers or digestive enzymes were observed, indicating dietary safety.
