Effect of dietary protein and lipid levels and protein-energy ratio on growth indices, feed utilization and body composition of freshwater prawn, Macrobrachium rosenbergii (de Man 1879) post larvae

摘要

A grow-out experiment was designed to determine the effect of different dietary protein, lipid levels and protein-energy (P:E) ratio on growth performance and feed utilization of the freshwater prawn, Macrobrachium rosenbergii post larvae (PL) culture in pond net enclosures (hapa, 3.75 mpd each) for 12 weeks (84 days). The experimental treatments were assigned in triplicate. Six test diets were formulated to contain three different protein levels (300, 350 and 400 g kgp# diet) and two lipid levels (100 and 140 g kgp# diet) in a factorial manner (3 x 2) to provided six different dietary P:E ratio: 16, 17, 18, 19, 20 and 21 mg CP kJp# gp#). The result showed that the highest significant (P
