Abstract
The present study was carried out to study the effect of supplementation of curry leaf powder at different levels on growth performance, serum biochemical profile, digestibility of nutrients, carcass characteristics and cost economics in broilers. One hundred and fifty, day-old chicks distributed randomly to five dietary groups each with three replicates of ten chicks and were offered broiler diets to meet the nutrient requirements (BIS, 2007). During the experiment, curry leaf powder was supplemented to the basal diet in pre-starter, starter and finisher phases as follows: Basal diet (T1), BD + 0.5% curry leaf powder (T2), BD + 1.0% curry leaf powder (T3), BD + 1.5% curry leaf powder (T4) and BD + 2.0% curry leaf powder (T5).
Results indicated that supplementation of curry leaf powder from 0.50 to 2.0% in the diet resulted in increased (P0.05) on overall feed intakes of birds. The serum biochemical profile of broilers revealed that supplementation of curry leaf powder up to 2.0% level in the diet had no effect (P>0.05) on serum albumin, globulin, HDL cholesterol, urea, creatinine, serum calcium and phosphorous content while it decreased significantly the serum total protein (P0.05) on digestibility of DM, OM, CP, EE and NFE while the CF digestibility decreased significantly (P0.05) on dressing percent, weight of head, shank, heart, liver, gizzard and giblets in broilers.
The feed cost/kg gain decreased by ₹ 4.32 in T2, ₹ 4.61 in T3, ₹ 1.66 in T4 while it increased by ₹ 1.37 in T5 groups of broilers fed diets supplemented with curry leaf powder as compared to the control. Thus, the present study indicated that curry leaf powder can be supplemented up to 1.0% level in the diet of broilers for decreasing feed cost/kg gain without any adverse effect on production performance of broilers.
