Yv. Wu et al., UTILIZATION OF PROTEIN-RICH ETHANOL COPRODUCTS FROM CORN IN TILAPIA FEED, Journal of the American Oil Chemists' Society, 71(9), 1994, pp. 1041-1043
Corn distiller's grains with solubles (CDGS), which is the residue fro
m ethanol fermentation of corn, were incorporated in tilapia (a warm-w
ater fish) diets that contained either 36% protein without fish meal o
r 32% protein with and without fish meal. A 103-day feeding study indi
cated that the three diets containing CDGS resulted in higher weights
of tilapia than fish fed a commercial fish feed containing 36% protein
and fish meal. The difference in weight gains between 32 and 36% prot
ein diets was not significant. Incorporating fish meal (6%) in diet ha
d no advantage over a diet without fish meal.
