An experiment was conducted to determine the effect of replacing maize with 10’% raw or differently
processed Icacinia manni on performance of broiler chickens. The processed I. manni which was each
incorporated into different diets were; fermented and fried (FF)‚ fermented with oil and fried (FWOF)‚
fermented and fried with oil (FFWO)‚ fermented with oil (FWO) and fermented only (FO) including the
raw only (RO) and the control. A total of 210 day old Anak chicks were used. Each of the seven
treatments was assigned 30 birds‚ replicated three times with 10 birds per replicate arranged in
completely randomized designed (CRD). The diets and water were fed at starter and finisher phases ad
libitum. Treatment effect on performance followed similar trend at both starter and finisher phases.
Control diet gave the highest final weight and daily gain (P<0.05) followed by FWO and FO and RO gave
the least. Feed intake was reduced by I. manni and was more pronounced in RO. Feed: gain ratio was
mostly affected by FF and RO. In conclusion‚ I. manni either raw or processed did not improve growth or
give similar results as the control. More research is suggested such as use of enzyme.
