Dietary effects of Dillenia indica leaves on growth performances, blood parameters, carcass characteristics and economic analysis in broilers

Abstract

The purpose of the study was to assess the effect of dried Dillenia indica leaves (DIL) and fermented Dillenia indica leaves (FDIL) on growth performances, blood parameters, carcass characteristics, and economic analysis in broiler. A total of 90 unsexed Ross 308 day old broiler chicks were distributed in three dietary treatment groups, T0 = Control (basal diet), T1 = (basal diet + 0.4% DIL on DM basis) and T2= (basal diet + 0.4% FDIL on DM basis). Each treatment group consists of three replications having 10 birds in a completely randomized design. Final weight and average daily gain (ADG) were increased while average daily feed intake (ADFI) and feed conversion ratio decreased significantly in treatment groups compared to control (P<0.05) during 3nd, 4th and overall period of the study. There was a significant reduction in blood cholesterol, triglyceride and LDL level in all treatment groups (P<0.0001) whereas higher HDL was found in T1 and lower in T0 group. Carcass parameters including breast, thigh meat, liver, and abdominal fat weight were significantly differed (P<0.05) relative to control. A significant increase in net profit and net profit/kg was found in treatment groups than control. In conclusion, dry and fermented Dillenia indica leaves might be a potential feed additive with improved growth performance, excellent lipid profile, and higher net profit for poultry feed.
