Shea nut meal is an agro-industrial by-product obtained from the processing of the nuts of the shea tree (Vitellariaparadoxa, Gaertn.) for fat. The cake was subjectedto cooking in boiling water for 30minutes and undergone fermentation for different periods of 2, 3 and 4 days, thereafter sundried and milled to obtained fermented-cooked shea butter cake meal (FCSBCM). A-28 d feeding trial was carried out to investigate the response of broiler chicksfed diets containing different FCSBCM replacing maize at 20% inclusion level on apparent nutrient digestibility and carcass yield. One hundred and fourty -four chicks were used in this study and randomly distributed to 4 experimental diets groups of 4 replicates with nine chicks each in a completely randomized design (CRD). The control diet (T1)containedmaizesoybean based diet while other diets contained maize being substituted at 20% by 2, 3 and 4-day FCSBCM in T2, T3 and T4 respectively. Feed intake and weight gain were recorded weekly. At 28 d, 2 birds per replicate were selected for metabolic cage evaluation and another 2 birds of comparable live weights per replicate were selected, slaughtered and eviscerated to determine carcass, breast and liver yield. The results showed that treatment means for feed intake and feed:gain were affected (p<0.05) by the dietary treatments. Birds fed control and T4 diets recorded lower (p<0.05) feed intake and feed:gain than those on T3 and T2 groups. Cost per kg gain of birds was significantly (p<0.05) higher in control groups compared to lower mean values obtained in birds fed different FCSBCM diets. The result of the study showed that apparent digestibility of crude protein (CP) and crude fibre (CF) was significantly (p<0.05) affected by the dietary treatments. Birds fed Diet T4 compared favourably with the control group and gave higher (p<0.05) mean values for CP and CF digestibility than those in diet T2 and T4 groups. Treatments means for carcass, breast and liver yield did not differ significantly (p>0.05) among the dietary treatments. In conclusion, longer period of fermentation has the potential to improve nutritive value of shea butter cake as this was reflected in birds fed 4d-FCSBCM diets comparing favourably with the control group in having better crude protein and crude fibre digestibility and hereby is recommended.
