Abstract: Background and Objective: Salvinia molesta is an aquatic plant that grows well in Rawa Pening, Central Java, Indonesia but it is invasive and typically causes environmental problems. Therefore, the government of Central Java is interested in reducing Salvinia in Rawa Pening. Based on a laboratory analysis, Salvinia contains 32% crude protein; thus, it may be used as broiler chicken feed. However, Salvinia molesta has not commonly been used in this way in Indonesia. The aim of this study was to determine the profitability of using S. molesta leaf meal in the diets of male broiler chickens. Methodology: One hundred male broiler chickens were divided into the following 4 treatments with 5 replicates each and 5 male broilers were reared in each replicate: T0 (0% S. molesta in the diet), T1 (6% S. molesta), T2 (12% S. molesta) and T3 (18% S. molesta). Results: The body weights of the chickens fed T1 did not differ in comparison to T0 and the FCRs of the birds fed T2 and T3 were similar to those of the birds fed T0. The feed consumption was similar among all treatments and no deleterious effects were observed during the experiment. Among the treatments, the T3 birds exhibited the most profitability. Therefore, Salvinia molesta can be used as broiler chicken feed at up to 6% of the diet. Conclusion: Incorporating Salvinia molesta at up to 6% of the diet may reduce feeding costs and thus increase profit.
