Nitrogen-corrected metabolizable energy (MEn) and digestibility coefficients of 5 samples of fish meal were determined using difference method. The basal diet was formulated to meet all nubition needs for chickens in experiment period. The five test diets were obtained through replacing 20 percent of basal diet by five samples of fish meal. The experiment was conducted on 180 thirty-five-day-old Luong Phuong chickens. The results of chemical compositions of five fish meal samples showed that protein content in the test samples was relatively high. There was an inverse correlation between protein and ash contents of fish meal. The MEN value offish meal was 2090.97 kcal/kg DM or 1864.73 kcal/kg as fed averagely. The MEn values of five test fish meal samples were lower than those of in literature or estimating values from chemical components. The apparent digestibility coefficients of nubients in commerson's anchovy meal were measured in ileal digesta and excreta. The results showed that nubients in the test fish meal were wen digested. With regarding crude protein, ether extract, organic matter, and nitrogen-free extractives, the apparent digestibilites determined in ileum were 77.5 percent, 48.94 percent, 75.56 percent and 67.45 percent, respectively. The total digestibility coefficients of CF and NDF of commerson's anchovy meal were 64.5 percent and 92.17 percent, respectively.
