dc.description.abstractA 28 day feeding trial was conducted to evaluate the effects of Carica papaya leaf meal with or without (dry) fermentation on growth performance, carcass characteristics, serum parameters, meat composition and oxidative stability of meat in broiler. A total of 135 day-old, ROSS-308 chicks was assigned to five treatment groups: Control (Basal diet), D1 (Basal diet + 0.5% Dry leaf on DM basis), D2 (Basal diet + 1.0% Dry leaf on DM basis), F1 (Basal diet + 0.5% Fermented leaf on DM basis) and F2 (Basal diet + 1.0% Fermented leaf on DM basis) having 3 replications consisting of 9 birds each in a completely randomized design. The results revealed that overall average daily gain (ADG) differed significantly (P<0.001) in all treatment groups compared to control. The average daily feed intake (ADFI) remained unchanged (P>0.05) among all dietary groups. A significantly (P<0.001) better final FCR was observed in all treatment groups in contrast to control. The weekly FCR remained unaffected except 4th week in which significant (P<0.001) change was observed. The proximate composition of breast meat showed significant (P<0.01) increase in crude protein (CP) content. Again, in thigh meat, crude protein and ether extract (EE) content differed significantly (P<0.01) among all dietary treatment groups than control. A significant (P<0.01) increase in serum HDL level and decrease in serum LDL and triglyceride level was observed in all treatment groups when compared with control. All visceral and total lymphatic organs weight remained unchanged (P>0.05) in all treatment groups in comparison to control. The oxidative stability of meat measuring thiobarbituric acid reactive substances (TBARS) had significantly (P<0.05) reduced in all additive treatment groups compared to control up to 3rd weeks. The net profit from papaya supplemented group differed significantly (P<0.001) than control. Finally, dry and fermented Carica papaya leaf increased ADG, serum HDL level, net profit and decreased FCR, serum LDL, triglyceride level and TBARS of meat. Hence, Papaya leaf meal showed beneficial effects on broiler and can be a potential source to be used as feed additive in broileren_US
