Abstract

The organ weight and feed cost analysis of broiler chickens fed graded levels of boiled Mucucna slaonei supplemented with maxigrain® enzyme was invested, using one hundred and twenty birds. The birds were allocated to four dietary treatments, each treatment was replicated thrice and each replicate had ten birds in a completely randomized design (CRD). Diet 2,3 and 4 contained boiled Mucuna Sloanei supplemented with maxigrain® enzyme, at 10%, 20% and 30% levels of inclusion in place of soya bean respectively. The experiment lasted for 56days. Feed and water were given at ad-libitum. Organ weights and feed cost analysis were measured. The proximate and gross energy of boiled mucuna sloanei were as follow; CP (29.03%), EE (2, 13%), CF (7.29%), ASH (4.71%) M (7.95%) DM (92.05%) AND GE (4.56Kcal/g). Boiled mucuna sloanei contained the following anti-nutritional factors, such as; Hydrogen Cyanide (22.17mg/kg) L-Dopa (4.15%) and Trypsin inhibitor (13.32T1U/mg). The organ weights showed significant difference (P<0.05) for all the parameters measured except proventriculus. T2 (1.94 and 1.93) compared favorably with Ti (0.59 and 1.35) for gizzard and liver respectively. The feed cost analysis of the diet revealed that there was no significant difference for cost/kg feed consumed only. T2 (N617.90) compared favorably with Ti (N560.17), for cost/kg weight gained among others. Conclusively, considering organ weights and feed cost analysis, especially cost/kg weight gain, T2 (10% dietary level inclusion of boiled mucuna sloanei in place of soyabean) compared favorably with Ti (control diet) and hence recommended.
