dc.description.abstractA study was conducted to evaluate the effect of feeding different animal protein sources viz. fish meal, meat bone meal and earthworm meal in the broiler diet under complete randomized block design. Day old broiler chicks (n=180) of vencobb-400 strain were divided into four treatment groups T0, T1, T2 and T3 which were further divided into three replicates with 15 chicks in each. All the birds were fed isonitrogenous and isocaloric standard diet. The birds in control group T0 was offered with standard poultry diet maize soy flake-based ration, T1 offered standard diet with inclusion of 5% fish meal, T2 offered standard diet with inclusion of 5% meat bone meal and T3 offered standard diet with inclusion of 5% earthworm meal. The result obtained from the study revealed that animal protein source supplementation with 5% earthworm meal significantly (P<0.05) enhanced the growth, feed intake, feed gain ratio and nutrient utilization, during both starter and finisher phase. In pre starter phase, supplementation of 5% meat bone meal significantly (P<0.05) enhanced the growth, feed intake and improved the feed gain ratio. Overall, supplementation of 5% earthworm meal exhibited higher live weight gain and better feed gain ratio. Highest dressing percentage, increased breast yield and low abdominal fat was recorded with improved organoleptic factors viz. flavour and juiciness of the meat. Hb and RBC values among blood parameters were significantly (P<0.05) higher in T3 group while other haematological parameters did not exhibit any significant differences. Increased phosphorus and calcium concentration were recorded with 5% earthworm supplementation in diet. Among biochemical parameters, significant difference (P<0.05) in protein and globulin concentrations were recorded, while plasma cholesterol and uric acid concentrations were significantly low (P<0.05) with 5% earthworm supplemented T3 treatment. Increased diameter of tibial bone positively influencing the thickness of tibial bone was observed in 5% earthworm supplemented treatment. Overall economic analysis revealed that broilers supplemented with 5% earthworm meal exhibited 25.30% higher gross profit as compared to the control as well as other treatment supplemented with fish meal and meat bone meal in terms of the body weight gain and feed efficiency.en_US
