ABSTRACT
An experiment was conducted to assess the potential of ginger-derived phyto-protease on production performance, gut health, immunity, and nutrient digestibility of broilers fed a high level of poultry by-product meal-based (PBM) diet. A total of 320-day-old broiler birds were assigned to four dietary treatments CON, N-CON, GPP1, and GPP2. CON a commercial corn-soybean meal-based diet as per ROSS-308 nutritional specifications. N-CON was a 6.5% PBM-based diet and to this group, a ginger-derived phyto-protease was added at two levels in treatments GPP1 (50 mg kg-1 feed) and GPP2 (100 mg kg-1 feed), respectively. Birds in group N-CON performed poorly for the performance traits like feed intake, weight gain and FCR. Phyto-protease addition at 100mg kg-1 feed exhibited significant effect on body weight, FCR, and carcass traits compared to the control. The highest body weight gain was recorded in birds fed GPP2, followed by birds on GPP1 and the lowest in N-CON fed birds. Ginger-derived phyto-protease supplementation significantly lowered serum cholesterol (TG and LDL) while HDL was raised in GPP2 compared to the N-CON group showing a positive effect on lipid profile. Protein digestibility and AME were improved in the GPP2 group compared to N-CON. Gut health was improved in terms of better integrity, villus height, crypt depth, and villus surface area by birds in the GPP2 group. These findings demonstrated that adverse effects associated with using a high level of locally available animal protein concentrates could be ameliorated by supplementing birds with a ginger phyto-protease enzyme.
