ABSTRACT
A feeding trial was conducted in a completely randomized design to evaluate the overall performance, blood constituents and carcass analysis of 5-day old Marshal broiler chicks that are fed with different diets; maize diet with and without AA supplements and unpeeled cassava root meal (UCRM) diet with and without AA supplements; of four replicates each and 10 chicken per replicate. The birds were assigned to these diets; feed, and water was given ad-libitum throughout the experiment. The experiment lasted for 7weeks. Feeds given were recorded and feed intake and weight gain were determined weekly. Data on overall performance, blood constituents and carcass quality were obtained. The data was subjected to analysis of variance and means were separated using new Duncan’s multiple range tests (1995). The interactive effect of the diet showed that the feed conversion ratio of the birds that consumed the control diet with amino acid supplement was significantly (p<0.05) higher (1.98) than those that were fed the control without amino acid supplement (2.17). The interactive effect of the diet also shows mortality to be insignificant (p>0.05). The interactive effect of the diets was only significant (p<0.05) in relation to white blood cell. The bird fed UCRM had a significantly (p<0.05) higher white blood cell in their blood (6.03) than those fed the other diets. The interactive effect of the diet shows that’s the birds fed the control diet with fAA had a significantly (p<0.05) higher level of WBC (4.98) than those without fAA in their feed (4.89). The same also applies to those fed UCRM; the birds had significantly (p<0.05) higher WBC (6.03) than UCRM without amino acid (4.97). The interactive effect of the diet was not significant (p>0.05) on any carcass parameter. Although the control with amino acids group showed a marginally higher weight of cut- parts when compared to the group with amino acids supplements.
