Exploring fish cutting discards, for instance, Marlin fish (Makaira indica) originated from traditional fish markets, may provide a product of fish meal at a cheaper price. The objective of this study was to evaluate the growth and economic value of broiler chickens fed the commercial diet, of which 20% were substituted with a mixture feed containing Marlin fish by-product meal (MFM) or commercial local fish meal (CFM) in 4 and 8% of inclusion. This study used 100 broiler chickens of strain MB202 in mixed batches. The study was performed in a completely randomized design consisting of five treatments, four replications, and five birds per experimental unit with the treatments: control (C) = 100% commercial diet (CD); CFM4 = 80% CD + 20% mixture feed with 4% CFM; CFM8 = 80% CD + 20% mixture feed with 8% CFM; MFM4 = 80% CD + 20% mixture feed with 4% MFM; and MFM8 = 80% CD + 20% mixture feed with 8% MFM. The results of this study showed that raising broilers fed the diet containing 4% MFM vs. 4% CFM for up to 35 days-old did not show the significant differences (p > 0.05) of all performance parameters. However, at the level of 8%, final body weight and daily body weight gain were significantly higher (p < 0.05) and feed conversion ratio was significantly better (p < 0.05) in MFM than in CFM-based diets. Protein efficiency ratio was very significantly higher (p < 0.01) in MFM than in CFM-based diets. Using MFM in broiler diet declined feed cost and increased income over feed costs, with the best economic receiving at 8% usage of MFM. In conclusion, using MFM in the diet resulted in better performances of broiler chickens and generated better economic value of production compared to using CFM. © 2025 Pontificia Universidade Catolica do Parana.
