Biochemical parameters, performance studies and lipid profile of broiler birds fed Bambara meal substituted diet

摘要

This research investigated the performance and serum enzymes activities of broiler birds fed 40% replacement level of Soybean meal (SBM) for Bambara groundnut meal (BGM). A total of 140 nexvly hatched broiler chicks (Arbor Acre strain) allocated in acompletely randomized design xvere used for the research. The experimental diets consisted of seven dietary treatments, four replicates of five birds per replicate. Treatment 1 (0% BGM) served as the control diet, T2-T7 contained equal concentration (40%> substitution level) of differently processed BGM. The activities of the transaminases (ALT and AST), gamma glutamyl transferase, the concentrations of serum total protein, creatinine, uric acid, as xvell as the serum lipid profile xvere monitored. Findings revealed that there xvere no significant (p>0.05) differences amongst the serum ALT of birds on boiled, fermentation xvith and fermentation xvithout decantation Bambara groundnut diets (0.922, 0.933 and 0.932 nmol min~(-1) mg~(-1)) respectively. Serum high density lipoprotein cholesterol xvere highest in roasted and raxv Bambara groundnut (1.86 mmol/L) meal diets. The drum stick (146.412 g) and the thigh (192.455g) of birds placed on raxv Bambara groundnut meal had higher significant (p<0.05) xveight gain values compared xvith those of birds on other experimental diets in the study. The results thus indicated that replacing Bambara groundnut at 40% against soya bean meal had no detrimental effects on measured indices, hence save for poultry farmers and consumers of the meat.
