Effect of Aqueous Moringa Oleifera (Lam) Leaf Extracts on Growth Performance and Carcass Characteristics of Hubbard Broiler Chicken

Two hundred and forty day old broiler chicks were used to investigate the effect of aqueous Moringa oleifera leaf extracts (AMOLE) on growth performance and carcass characteristics of broiler chicken. The birds were randomly allocated into six treatments with four replicates, and each replicate containing 10 broiler chicks; the CRD was used. The treatments contained AMOLE(0+) (positive control with antibiotic treatment), AMOLE(0-) (negative control with ordinary water), AMOLE(60) (60 ml/l), AMOLE(90) (90 ml/l), AMOLE(120) (120 ml/l) and AMOLE(150) (150 ml/l) inclusion levels of AMOLE, respectively. Birds on positive control had the highest final body weight and growth rate (2392.00 g and 53.61 g respectively) and the ones on 150 ml/l of AMOLE had the least (2042.00 g and 45.37 g respectively). Results of feed intake showed that birds on positive control had the highest (84.70 g) and the ones on 90 ml/litre of AMOLE had the lowest (73.19 g); while the results of feed conversion ratio indicated that birds on AMOLE(90) and AMOLE(120) performed better than the positive control treatment. Birds on the AMOLE had similar dressing percentages though that of positive control was highest (94.93 %); while those on AMOLE(60) and AMOLE(150) had the highest large intestine and lung weights respectively. Aqueous Moringa oleifera leaf extract can be included up to 90 ml/litre in the drinking water of broiler chicken for reduced feed intake (12.83 %) and improved feed conversion efficiency (9.11) thus, AMOLE can be used to replace synthetic antibiotics as growth promoter.
