Impact of Partial Substitution of Maize by Indomie Waste Meal on Growth Performance, Serum Metabolites, Meat Quality, and Economic Efficiency of Broiler Chickens

this study was to assess the effects of using Indomie waste meal (IWM) in place of maize in broilers' diets on growth performance, carcass characteristics, serum biochemicals, meat quality, and economic efficiency. 120 females Cobb-500, one day old, were divided into five dietary groups, with 3 replicates of 8 individuals per replicate, and were fed with 0 %, 10%, 20%, 30%, and 40 % IWM in place of maize. Results obtained clearly indicated that all graded levels of IWM had no significant impact on any of the growth parameters, immunological indices, protein profile, uric acid, alanine aminotransferase, and aspartate aminotransferase. However, high concentrations of IWM (30, 40%) significantly increased total cholesterol and triglyceride and reduced highdensity lipoprotein. Carcass assessment showed no significant difference among different diets except for the weight of gizzard and liver, which significantly decreased in the group fed 40% IWM compared to the control one fed 0% IWM. of the meat quality examined, the fat and ash % were significantly affected by the dietary treatments in various trends, with the control group having the lowest percentages (1.62% and 2.11%, respectively) and the birds fed 40% IWM having the greatest percentages (2.33% and 2.76%, respectively). The economic evaluation showed that birds fed 40% IWM yielded the highest net profit and lowest cost per kg gain as compared to control ones. Therefore, IWM can be used in broiler diets up to 40% to improve production costs without negatively affecting the birds' growth performance, physiological state, or meat quality
