Abstract
The plants originated from an agroforestry system have gained immense importance in livestock health and production. The trial was planned to examine the effects of Moringa oleifera leaf extract (MLE) supplementation on the performance, blood metabolites, immunity and lipid peroxidation in broiler chicks. A total of 350 day old broiler chicks were divided into negative control (MLE0), positive control (antibiotic; AB-enro), M. oleifera supplementation at the concentration of 60 (MLE60), 90 (MLE90) and 120 mL/L (MLE120) of drinking water. Performance parameters such as feed intake, body weight and feed conversion ratio, antibody titer against Newcastle disease and infectious bronchitis, heterophils and lymphocytes ratio, blood glucose, protein, and malanodialdehyde were determined. The results showed that carcass yield was significantly (p < 0.05) higher in MLE90 followed by MLE120 and AB-enro. MLE60 and MLE90 showed significant (p < 0.05) increase in antibody titer against New-castle (ND) and Infectious-bronchitis (IB) respectively. Significantly (p < 0.05) lower Heterophil to lymphocyte (H:L) ratio was observed in MLE90 and MLE120 compared to the negative control. Significantly (p < 0.05) lower blood glucose concentration and significantly (p < 0.05) higher mean serum protein value were found in MLE120. The MLE120 showed significantly (p < 0.05) lower concentration of malanodialdehyde (MDA). It was concluded that M. oleifera leaf extract supplementation at the concentration of 120 mL/L of drinking water improved carcass yield, immunity, blood metabolites and reduced lipid peroxidation in broiler chicks.
