Abstract: Background and Objective: Plant proteins have been reported to be useful in poultry nutrition in this era of sincere efforts of reducing cost of production. This study was conducted to investigate how far fish meal (FM) can be replaced with duckweed meal (DWM) in broilers diets at starter (0-4 weeks) and finisher (4-8 weeks) phases. Materials and Methods: One hundred and fifty days old unsexed Anak strain of broiler chicks were randomly allotted into (5) dietary treatment groups (T1-T5) with DWM replacing FM at 0, 25, 50, 75 and 100%, respectively in a completely randomized design. Each dietary group was replicated thrice with ten birds. Performance characteristics of the birds were studied over 8 weeks. Blood samples were collected at 28th and 56th day of the experiment for haematology and serum metabolites analyses. Relative weights of the internal organs were determined at the end of the feeding trial. All data generated were subjected to analysis of variance statistically. Results: Daily feed intake, weekly body weight and total body weight gain were not significantly (p>0.05) improved by the dietary treatments and also feed conversion ratio and feed conversion efficiency at starter and finisher phases with the best results from birds on control diet and least from T5 were not significant. Haematological and serum parameters measured were not significantly (p>0.05) improved by the treatments at both phases, so also the relative weights of the internal organs. However, birds on T2 compared favourably with the control group at both phases in all parameters measured. Birds on T5 had the highest rate of mortality at both phases. Conclusion: The DWM can be used to replace FM up to 25% at starter phase and 50% at finisher phase beyond which the birds may be negatively affected.
