ABSTRACT This study was conducted to determine the effect of bee pollen inclusion on the performance and gut morphology of Ross 308 broiler chickens. A total of 240-day-old chicks (120 males and 120 females) were allocated to 4 treatments in a randomized complete block design (RCBD) with sex as a block. Each experimental group was replicated 3 times with 10 chicks per replicate, with an average weight of 40 ± 5g per bird. Body weight and feed intake were measured on a weekly basis to calculate the feed conversion ratio. Gut morphology was measured on days 21 and 42. Data were analysed using the General Linear Model procedures of the Statistical Analysis System.Bee pollen inclusion in starter diets had an effect (p<0.05) on body weight and live weight gain of male Ross 308 broiler chickens. The different inclusion levels of bee pollen had an effect (p<0.05) on the gut morphology of Ross 308 broiler chickens. The ileum lengths of female broiler chickens were significantly wider (p<0.05) in comparison with male chickens. This may suggest that bee pollen inclusion has a beneficial effect on broiler chickens gut morphology during the early stages of development. It can be concluded that natural substances such as bee pollen can be a possible feed additive to replace synthetic antibiotics, since such compounds are essential for the growth and development of poultry gut. 30 240dayold dayold 240 day old (12 12 females RCBD (RCBD 1 replicate g bird ratio 2 42 SystemBee System Bee p<0.05 p005 p 0 05 (p<0.05 antibiotics 24 (1 p<0.0 p00 (p<0.0 ( p<0. p0 (p<0. p<0 (p<0 p< (p< (p

ABSTRACT 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 AMOLE0+ (positive control with antibiotic treatment), AMOLE0- (negative control with ordinary water), AMOLE60 (60 ml/l), AMOLE90 (90 ml/l), AMOLE120 (120 ml/l) and AMOLE150 (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 AMOLE90 and AMOLE120 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 AMOLE60 and AMOLE150 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.
