Implication

Feeding trial shows that hydrolyzed feather meal affects growth performance and flesh quality in yellow catfish, indicating potential dietary limits.

Key Points

  • Growth performance decreased significantly with increasing hydrolyzed feather meal inclusion, impacting fish health.
  • Weight gain rate and specific growth rate indicated a maximum 16.67% fish meal replacement for optimal growth in yellow catfish.
  • Intestinal enzyme activities improved with hydrolyzed feather meal, enhancing flesh quality despite negative impacts on immune function.
  • High hydrolyzed feather meal levels led to negative serum indicators and skin discoloration, highlighting dietary caution.
