Effects of Bee Pollen Inclusion on the Performance and Gut Morphology of Ross 308 Broiler Chickens

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.
