The effect of dietary treatments on growth performance, haematological and biochemical indices of finisher broilers as well as economics of broiler production were determined in this fermented cassava flour/blood mixture code-named "cassablood". The control diet (T1) contained 0% cassablood, while diets 2, 3 and 4 contained 20%, 25% and 30% cassablood respectively. 120 four weeks old Anak broiler chicken were randomly allocated the 4 diets with 30 birds per treatment replicated 3 times with ten 10 broilers per replicate in a completely randomized design (CRD). Treatment effects on final body weight, final weight gain, feed intake and seed conversion ratio were significant (P<0.05). Birds fed cassablood based diets compared favourably with the control diet. 20% cassablood inclusion performed equally with the control diet in feed intake, body weight gain and feed conversion ratio.All dietary groups also showed no significant differences (P>0.05) in most haematological and serum biochemical indices of broilers except in cholesterol, glucose and triglyceride contentswhichdiffered (P<0.05) significantly. Similarly, chicken on 20% and 25% inclusion levels produced significantly (P < 0.05) higher economic gains in terms of feed cost per kilogram of broiler among all the treatments. Therefore, 20 - 25% cassablood dietary inclusion level was recommended in broiler diet for production and profit maximization.

A 28-day feeding trial involving two hundred and forty (240) 5 week old broilers was carried out in a completely randomized design to evaluate the growth and economic analysis of finisher broiler chicken. For this purpose, an ingredient named "wheatblood" was prepared by mixing wheat bran and abattoir blood. The test ingredient was mixed at dietary levels of 0% 20%, 25% and 30% respectively, named T1, T2, T3 and T4 where T1 served as the control. Feed and water were supplied ad libitum for 28 days the trial lasted. The parameters considered were feed intake, body weight gain, feed efficiency and cost benefit analysis. Results showed that feed intake, weight gain and feed efficiency of birds differed significantly (P < 0.05) among treatments. However, there was no significant difference (P>0.05) between T1 and T2 in the 3 parameters and between T3 and T4 except in feed efficiency. Feed cost reduced with increase in wheatblood inclusion in the diets. Indeed, all wheatblood based diets were significantly (P < 0.05) cheaper than the control, and thus, cost less to produce one kilogramme of broiler. However, there was no significant difference between T2 and T3 in cost of kg feed and between T2 and T4 in cost of feed per kg broiler which was the cheapest. Therefore, 20% inclusion of wheatblood produced best growth performance and economic gains and provided cheap and efficient utilization of abattoir blood in poultry diets. It is concluded that wheatblood inclusion in broiler finisher ration significantly reduce production cost without adverse effect on growth parameters.
