Six isonitrogenous and isolipidic diets were prepared by adding three levels of PBM at 0, 5 and 10% and two levels of BC at 0 and 4%. Triplicate groups of juvenile amberjack (3.00 g, 20 fish per tank) were fed the respective test diets twice daily to apparent satiation for 45 days. Results indicated that PBM had no significant (P>0.05) effect on growth performance and feed utilization of fish. Inclusion of BC significantly (P<0.05) improved the performance of fish. However, no interaction was found between PBM and BC. Survival was not affected by PBM, BC or their interaction. Whole body proximate composition was also significantly influenced by BC supplementation. Blood chemistry showed some differences but the values were comparable among the dietary groups. The present study demonstrated that BC supplementation is effective for improving the utilization of a plant by-product mixture in low fishmeal and comparatively higher level of plant protein based diet for juvenile amberjack. It is assuming that BC could absorb the noxious substances present in PBM which might improve the utilization of diets. Based on the present experiment, it is concluded that 5-10% PBM along with 4% BC in 25% fishmeal based diet is effective supplementation for better performances of juvenile amberjack.}, pages = {1--12}, title = {Improved utilization of a Plant By-Products Mixture}, volume = {34}, year = {2013}, yomi = {イシカワ, マナブ and コシオ, シュンスケ} }
