The current high cost of conventional feed ingredients has necessitated the exploration into application of different treatments on agro waste products in the bid to harness their potentials to fit in as feed ingredient in feeding broilers. Such treatments could impact on carcass and organs of the birds. A 3-week trial was therefore conducted to determine the effect of NaOH treated rice husk meal with enzyme supplementation on the carcass and organ characteristics of broiler finisher chickens. Four (4) experimental broiler finisher diets were formulated such that the control diet (B1) did not contain rice husk, while B2, B3 and B4 had NaOH treated rice husk at 5, 10 and 15% respectively with 0.1% enzyme supplementation. A total of one hundred and twenty (120) Anak strain of finishing broiler chickens of 28 days post hatch were assigned to four (4) dietary treatments. Each treatment had fifteen (30) birds, which was replicated three (3) times with 10 broilers per replicate. The birds were managed under deep litter system and fed ad libitum for 28 days. At termination of the experiment, the birds were slaughtered for carcass and organ assessment. The result showed that there was no significant (P<0.05) difference in carcass and organ parameters analyzed except for eviscerated weight. It was concluded that NaOH treated Rice Husk meal can be included in broiler diet up to 15% with 0.1% enzyme supplementation without deleterious effect on carcass and organ parameters.
