Abstract

56 days’ experiment was carried out to study performance evaluation and cost benefits of broiler chickens fed white sorghum supplemented with graded levels of synthetic methionine. White sorghum was supplemented with synthetic methionione at 0.10, 0.20, 0.30, 0.40 and 0.50% for T1, T2, T3, T4 and T5 respectively in a Completely Randomized Design. Three hundred (300) day-old unsexed broiler chickens were randomly assigned to 5 treatments of 60 birds and 3 replicates of 20 birds. The study was carried out in two phas es; starter (1-4 weeks) and finisher (5-8 weeks). Results showed similar trends in both phases as Daily Feed Intake, All parameters measuared were not significantly different. Daily feed intake and weight gain increased slightly with increased levels of synthetic methionine inclusion. There was also decreased in mortality rate with increased levels of methionine inclusion. Total feed cost (TFC/(N)), total weight gain TWG/kg) and Feed cost (N/kg gain) were better in T1 (N1,089.73, 1.9kg and N422.34) respectively. In conclusion, white sorghum can be supplemented with synthetic methionone upto 0.50% without any deleterious effect on performance with the best economic benefits in T1.
