Effects of phosphate and phytase supplementation on phytate degradation in rainbow trout (Oncorhynchus mykiss W.) and Atlantic salmon (Salmo salar L.)

Highlights

  • The same diet was used in Atlantic salmon and rainbow trout to study gastrointestinal phytate breakdown.
  • The intrinsic phytate degradation potential of Atlantic salmon and rainbow trout seems to be similar and relatively low.
  • Phytase supplementation effects were much higher in rainbow trout than Atlantic salmon.
  • Supplementation of monoammonium phosphate decreased phytase efficacy in Atlantic salmon.
