Serum metabolites of broilers fed graded levels of beniseed (Sesamum indicum L.) waste meal in place of maize (Zea mays linn)

Abstract

A 56-day feeding trial was conducted to investigate the effects of dietary replacement of maize with beniseed waste meal (BSW) on the carcass  characteristics, organs weights, hematological and serum biochemical indices of broiler chicken. A total of 180 days old Marshal broiler chicks were randomly allotted to six treatments, each having three replicates of ten birds per replicate. Six experimental diets were formulated as follows; D1 (100% Maize: 0% BSW), D2 (80% Maize: 20% BSW), D3 (60% Maize: 40% BSW), D4 (40% Maize: 60% BSW), D5 (20% Maize: 80% BSW) and D6 (0% Maize: 100% BSW) for both broiler starters and finishers. The live weight, eviscerated weight, dressed weight, neck, thigh, wings and lower back weights were significantly (P < 0.05) affected by the dietary treatments. The highest percentage dressed weight (63.52) obtained in D3 (40% BSW) was significantly (P < 0.05) different from 60.87 (0% BSW), 61.68 (20% BSW) 60.00 (60% BSW), 55.18 (80% BSW) and 56.52 (100% BSW). The organs (lungs, liver, kidney, intestine, gizzard and proventriculus) monitored were significantly (P < 0.05) affected by the dietary treatments. Heart, pancreas and spleen were similar among the treatments. The serum biochemistry and haematological parameters measured were not significantly (P > 0.05) affected by the dietary treatments. It was concluded that maize could be safely replaced with beniseed waste meal up to 100% level (55% BSW) in broilers diets.
