LIVE WEIGHT, BLOOD PARAMETERS AND CARCASS QUALITY OF BROILER FED DRY AND FERMENTED LEMON PEELS AND OLIVE LEAVES

Abstract

To determine the combined effects of lemon peels and olive leaves feed on broiler growth performance, carcass characteristics, serum parameters, meat composition, and oxidative stability of meat, a 35-day feeding trial was conducted. A total of 144 day old Cobb 500 chicks was assigned to six treatment groups: Control (Basal diet), D1 (Basal diet + 0.8% Dry lemon peels and olive leaves on DM basis), D2 (Basal diet + 1.2% Dry lemon peels and olive leaves on DM basis), F1 (Basal diet + 0.8% Fermented lemon peels and olive leaves on DM basis), F2 (Basal diet + 1.2% Fermented lemon peels and olive leaves on DM basis) and AB (Basal diet+ Antibiotics) having 3 replications consisting of 8 birds each in a completely randomized design. The results indicated that all treatment groups differed significantly (P<0.05) from the control in the overall average daily gain (ADG). There is no significant difference in average daily feed intake among all dietary groups. The results indicated that all treatment groups differed significantly (P<0.05) from the control in the overall FCR. In terms of crude protein, ether extract and ash, there were significant (P<0.05) changes in the chemical composition of meat in the treatment group. All treatment groups showed a significant (P<0.05) decrease in serum cholesterol, LDL and triglyceride levels when compared to the control group. In all treatment groups compared to control group from 0 day to third weeks, the oxidative stability of meat as determined by thiobarbituric acid reactive substances (TBARS) had significantly (P<0.05) decreased. The net profit from treatment supplemented group differed significantly (P<0.001) than control. Lemon peels and olive leaves increased ADG, net profit and decreased FCR, serum LDL, triglyceride level and TBARS of meat. Hence, lemon peels and olive leaves meal showed beneficial effects on broiler and can be a potential source to be used as feed additive in broiler.
