Fish Feeding Trials Prove DDGS A Winning Ingredient

U.S. Grains Council recognized an opportunity to increase the utilization of distiller's dried grains with solubles (DDGS), a co-product of U.S. ethanol production, in the rapidly growing fish farming (aquaculture) industry.
According to Dr. Budi Tangendjaja, USGC consultant in Southeast Asia, aquaculture is one of the fastest growing food producing industries in the world.
The Council embarked on an initiative to test DDGS as a potential ingredient for feeding fish in Vietnam due to the anticipated economic and nutritional value.
The trials were conducted using Vietnamese catfish tra, common carp and red tilapia.
"The ethanol co-product has shown to be economically feasible for animal feed especially in dairy and beef cattle, swine and poultry diets. However, very limited information was available for feeding DDGS to fish, despite the given benefits of the ingredient such as high protein content (28 percent) and a relatively cheaper cost," said Dr. Tangendjaja.
The results of using DDGS at a 15 percent inclusion rate in all three species concluded the co-product slightly improved the growth rate and reduced mortality. Feeding DDGS at a 15 percent inclusion ratio also improved feed conversion in catfish from 3.01 in the control diet to 1.95 in the DDGS diet.
The feeding trials proved feeding DDGS to all three species did not negatively impact meat quality nor did it affect color of the fillet, which was a preconceived concern of end-users.
"There is an indication that feeding DDGS at a 15 percent inclusion ratio would improve feed utilization, enhance growth performance and decrease the cost of a feed formula," said Tangendjaja.

This sounds good for use in aquaculture of certain sp. However it's like the writer stated, it was used for catfish. It will be good to know the proximate composition of the distiller's grain and the fiber content. However I think it might be better for tilapia and carp than for high protein demanding fish. In any case, things like this needs futher research to prove their efficacy as feed additives.

This is good news to fish farmers. The analysis of the feedstuff should be put into consideration because the processing techniques depend on the equipment use in the extraction process.

Dear Sir,
This research is of particular benefit to developing countries where the cost of feeding the fish is the major limiting factor to aquacultures developement in Nigeria and other developing countries. The research should have included the cost of the spent grain per ton so that appropriate comparative analysis should be arrived at before concluding its economic and nutrional advantage.
Thanks,
Dr Igwe Eddy
