The study reported herein was conducted to determine the effect of breadfruit (Artocarpus altilis) flour on growth performance and meat quality parameters of broiler chickens. Ninety-day old Cobb 500 broiler chicks were randomly assigned into three dietary treatments as control (0% BFF), treatment 1 (5% BFF), and treatment 2 (10% BFF) in a booster, starter and finisher diets, respectively. Each treatment replicated three times with 10 birds per replicate. Body weight, feed intake and feed conversion ratio (FCR) were recorded for 5-weeks. On day-36, two birds from each replicate were randomly selected and were slaughtered for carcass analysis. Data were analysed using a one-way analysis for a variance by using Minitab 17 software. Tukey multiple range test was used to determine the significant differences between experimented groups at p<0.05. There was no significant difference (p>0.05) on feed intake of broilers fed different dietary treatments. Birds fed 10% BFF achieved the highest (p<0.05) weight gain and the lowest FCR compared to other treatments. The highest (p<0.05) dressing percentage and the relative weights (p<0.05) of heart, liver, and intestines were recorded from the birds fed the diet having 10% BFF. No significant effect (p>0.05) was observed in proximate composition and meat quality parameters tested. Sensory attributes were higher in birds fed treatment 2 and the highest (p<0.05) overall acceptability was recorded by the birds fed with 10% BFF. In conclusion, breadfruit flour can be incorporated into broiler diets at a 10% level to enhance body weight, good carcass yield, and to improve meat quality parameters of broiler chickens without any negative effects.
