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

ABSTRACT This study aimed to evaluate the apparent digestibility coefficients (ADCs) of dry matter, crude protein, gross energy, and minerals of marine fish meal (MFM), salmon meal (SM), tilapia by-product meal (TBM), meat and bone meal (MBM), poultry by-product meal (PBM), blood meal (BM), and feat...

Groups of 12 fish were fed the experimental diet three times a day until apparent satiation, and the fecal samples were collected from an accumulation device. SM and PBM exhibited the highest digestibility values for dry matter, crude protein, and gross energy, while MBM and FM presented significantly lower ADCs for dry matter. BM and FM exhibited higher ADCs for phosphorus, 65.05 and 63.87%, respectively. The ADCs for calcium were 58.8% for MFM, 56.69% for TBM, and 60.08% for PBM. PBM and FM had the highest iron ADCs, 44.01 and 46.29%, respectively. Magnesium ADCs ranged from 44.87% for MBM to 75.50% for TBM. BM had the highest digestibility for zinc (62.77%), whereas MBM (36.68%) and FM (39.39%) had the lowest. In general, SM and PBM showed higher values as feedstuffs for silver catfish feeds.
