Abstract:
The objective of the present study was to evaluate the effect of partial replacement of soybean meal with combination of other plant protein sources supplemented with multi-exogenous enzymes on the growth performance, carcass characteristics and economics in broiler diet. Two hundred and forty (n=240) day-old Ross 308® broiler chicks were purchased from commercial hatchery and randomly divided into six dietary treatments with five replicates having 08 chicks/replicate. Six iso-nitrogenous and iso-caloric experimental diets were formulated for starter (Crude protein: 22%; Metabolizable energy: 3000 kcal/kg) and finisher diets (Crude protein: 20%; Metabolizable energy: 3200 kcal/kg) were formulated with and without supplementation of multi-exogenous enzymes with varying levels of other plant protein meal sources i.e. 0 %, 25 % and 50 %. Each experimental diet was randomly allotted to five replicates for the duration of the trial that lasted for 35 days. Data were recorded weekly to determine feed intake, body weight gain and FCR. At the end of the experimental trial, one bird from each replicate was randomly slaughtered to analyze the carcass characteristics. The collected data were subjected to statistically analyze using 3×2 factorial arrangement under completely randomized design. Feed intake and feed conversion ration across the treatments were unaffected by multi-exogenous enzymes supplementation. Body weight gain was significantly affected (P<0.05) by multi-exogenous enzymes supplementation in broiler diet. Diet with 100% soybean meal with and without multi-enzymes, and the diet with 50% plant protein source with supplemental multi-exogenous enzymes showed better body weight gain. Dressing, carcass, chest and thigh percentage were non-significant across all the treatments. However the abdominal fat percentage were higher in treatments with 100% soybean meal with or without multi-exogenous enzymes and 50% plant protein meals combination supplemented with multi-exogenous enzymes. Based on these findings, it can be concluded that the plant protein meals combination can replace soybean meal up to 50%, along with multi-exogenous enzyme and did not negatively affect growth performance and carcass parameters.
