Phyto-additives in poultry diets enhance growth, feed efficiency and product quality and minimise the possible risk of residues from chemical additives. There are reports on the use of noni (Morinda citrifolia) fruit powder as phyto-additive in poultry diets but information on the effect of fruit ripening is scanty. Hence, this study compared the effect of unripe and ripe noni fruit powder on broiler performance. A control diet without and 4 diets containing two levels (0.25 and 0.5%) unripe and ripe fruit powder were fed to 5 replicates containing 6 Cobb 500 broilers in a completely randomized design. Data collection was on growth performance, nutrient digestibility, and carcass and organ measurements. In the starter (8-21 d), feed intake (FI) reduced on 0.5% unripe powder (P<0.05) but did not differ between the control and 0.25% ripe powder (P>0.05). Nitrogen retention reduced on 0.25% unripe powder compared to the control and the ripe powder (P<0.05). Poorer dressing percentage was observed on 0.5% ripe powder (P<0.05). Breast weight was increased and thigh weight reduced on 0.25% ripe and 0.5% unripe powder (P<0.05). In conclusion, up to 0.5% noni, fruit powder has no beneficial effect on broiler growth, but the stage of ripening may influences protein digestibility and dressing percentage. We recommend more research into feed processing and diet composition.
