Interpretive Summary:

Technical Abstract: A feeding trial was performed to investigate inclusion levels of distillers dried grains with solubles (DDGS) and soybean meal (SM) used in the diets of juvenile yellow perch (Perca flavescens). Six isocaloric (3.22 ± 0.02 kcal/g SE), isonitrogenous (30.1 ± 0.2% SE) experimental diets were formulated to contain 0/31.5, 10/26, 20/20.5, 30/15, 40/9.5, and 50%/4% DDGS/SM. Fish fed 40%/9.5% DDGS/SM exhibited the highest weight gain (WG) and heptasomatic index (HSI) values, while fish fed diets 20%/20.5% and 30%/15% DDGS/SM exhibited statistically similar WG. Fish fed 50%/4% DDGS/SM had statistically lower WG, Fulton condition, and apparent digestibility values than all other fish. Crude protein and lipid levels did not significantly differ among female or male yellow perch fed differing concentrations of DDGS and SM, but significant differences did occur between female and male crude protein and lipid concentrations when fed 10%/26% DDGS/SM and 20%/20.5% DDGS/SM, respectively. Results indicated that yellow perch can utilize up to 49.5% plant-based proteins (DDGS + SM) without negatively affecting growth, feeding efficiency and muscle composition.
