Utilizing corn-fermented protein (CFP) as a substitute for soybean meal (SBM) in aquafeeds presents a promising option due to its dependable supply and cost-effectiveness. In this study, two growth trials were performed to evaluate the effectiveness of CFP products such as CFPA (48% crude protein - CP), CFPB1 (50% CP), and CFPB2 (60% CP) from two different sources (A, B) in practical diets for the juvenile white shrimp L. vannamei. The test diets in both trials were formulated to be isonitrogenous and isolipidic (36% crude protein, 6% crude lipid). These diets were produced by supplementing the basal diet with 5, 10, 15, and 20% CFPA or 4, 8, 12, and 16% of CFPB1 and CFPB2 to replace SBM on an isonitrogenous basis. In the first trial, shrimp (1.02 ± 0.02g mean weight, 15 shrimp per tank, n=6) were offered diets for six weeks. Growth parameters and protein retention showed no significant differences among the diets. However, a significant feed conversion ratio (FCR) increase was observed when shrimp were fed a diet containing 20% CFPA compared to the basal and 5% CFPA diets. In the second seven-week trial, shrimp (0.55 ± 0.01g, 15 shrimp per tank, n=5) received experimental diets, including CFPB with two protein sources, CFPB1 and CFPB2. No differences were observed in growth performance. This research highlights the potential of CFP as a protein source in shrimp diets and improves aquaculture’s economic and environmental sustainability by expanding the range of feed components and identifying optimal inclusion levels.
