Mineral digestibility of different animal sources for the silver catfish Rhamdia voulezi

This study aimed to evaluate the apparent digestibility coefficients (ADCs) of dry matter, crude protein, gross energy, and minerals marine fish meal (MFM), salmon (SM), tilapia by-product (TBM), meat bone (MBM), poultry (PBM), blood (BM), feather (FM) by silver catfish Rhamdia voulezi. Groups 12 were fed experimental diet three times a day until satiation, fecal samples collected from an accumulation device. SM PBM exhibited highest values for while MBM FM presented significantly lower ADCs matter. BM higher phosphorus, 65.05 63.87%, respectively. The calcium 58.8% MFM, 56.69% TBM, 60.08% PBM. had iron ADCs, 44.01 46.29%, Magnesium ranged 44.87% 75.50% TBM. zinc (62.77%), whereas (36.68%) (39.39%) lowest. In general, showed as feedstuffs feeds. At same time, was TBM macronutrients such iron, zinc.
