Partial replacement of fishmeal with meat and bone meal and tuna byproducts meal in practical diets for juvenile spotted rose snapper Lutjanus guttatus
A 120 days feeding trial was conducted to evaluate diets in which fish meal (FM) was replaced with meat and bone meal (MBM) or tuna byproduct meal (TBM) on growth performance, apparent digestibility and hematological parameters of juvenile spotted rose sna pper (SRS) L. guttatus .

| Sumario: | A 120 days feeding trial was conducted to evaluate diets in which fish meal (FM) was replaced with meat and bone meal (MBM) or tuna byproduct meal (TBM) on growth performance, apparent digestibility and hematological parameters of juvenile spotted rose sna pper (SRS) L. guttatus . Three isonitrogenous compounds (47.6 - 49.0%) and isoenergetic (20.9 - 22.9 kJ g - 1 ) diets were formulated. A control diet contained FM as a main protein source (D - FM) and two diets with 35% of fish meal protein replaced by MBM or TBM pr otein (D - MBM, D - TBM). Each diet was fed to triplicate groups of 20 SRS juvenile (initial weight 8.2 ± 0.02 g) to apparent satiation three times a day. Growth performance, hematological parameters and apparent digestibility of SRS fed D - MBM or D - TBM diets w ere not significantly different from D - FM diet. However, the whole body crude protein was significantly higher in D - MBM group than D - TBM group, and the values were comparable to D - FM group. Based on these results, the meat and bone meal is an economical an d viable option, as tuna byproduct meal in practical diets for juvenile spotted rose snapper. |
