Abstract: An experiment was conducted with 128, 7 days old Vencobb broiler chicks to study the effect of feeding different protein concentrates (Jasoprot, Provita, Fishpro) on the performance of broiler. The dietary treatment was fish meal based control diet where fish meal was replaced by different protein concentrates. The live weight of broilers fed different protein concentrates differed significantly (p< 0.01) at 4, 5 and 6^th weeks of age. The live weight gain during 2-6 weeks in Jasoprot was higher than other treatments. Broilers fed Josoprot diet had better feed conversion ratio than other dietary treatments. At 6 weeks of age, the production number in Jasoprot diet was significantly (p< 0.01) higher than other dietary treatments. Similar trend was observed in performance index. Survivability was similar in different treatments during the experimental period. Net profit was higher (p< 0.01) in Jasoprot diet as compared to other treatments. It can be concluded that protein concentrates available in the market could replace fish meal from broiler diet with satisfactory performance. However, Jasoprot seems to be the best as protein concentrates studied in respect of broiler performance and financial return.
