Effects of Dietary Incorporation of Neem (Azadirachta indica), Moringa (Moringa oleifera), and Jute (Corchorus olitorius) Leaf Powder on Production Performance and Blood Indices of Broiler Chickens as a Substitute of Antibiotic

The study was planned to determine the effects of dietary incorporation of Neem (Azadirachta indica), Moringa (Moringa oleifera), and Jute (Corchorus olitorius) leaf powder on production performance, carcass traits, and blood indices of broiler chickens as a substitute for the antibiotic. A total of 200-day-old Cobb 500 broiler chicks were divided randomly into 5 experimental groups. Whereas groups T1, T2, T3, and T4 were offered basal feed supplemented with 2% Neem Leaf Powder (NLP), 2% Moringa Leaf Powder (MLP), 2% Jute Leaf Powder (JLP), and antibiotics, respectively. In this research, the total feed consumption of birds was significantly (P < 0.05) lower in the T1 and T2 group than in the T3 and T4 group. Final live weight was significantly (P < 0.05) higher in 2% MLP treated group T2 followed by T1, T3, and T0 group. Significantly (P < 0.05) better feed conversion ratio (FCR) was found in the T2 group compared to T0, T3, and T4 groups. There found no significant (P > 0.05) effect of treatments on the survivability percentage of birds. All the treatment groups showed an insignificant (P > 0.05) effect on dressing percentage and organs (liver, heart, and gizzard) weight of broiler chicken. Weight of immune organs (spleen and bursa) and blood parameters (concentration of hemoglobin, glucose, and cholesterol) were not influenced (P > 0.05) by dietary addition. Birds fed the lower amount of feed, higher body weight, and improved FCR were found in the 2% MLP treated group. In overall aspects, the effectiveness of 2% MLP addition was better than 2% NLP and 2% JLP as an antibiotic alternative.
