Texas—Addison Lawrence and Dried Distiller Grains


About two years ago Holly Jensen, a journalist, wrote an interesting story about Dried Distillers Grains with Solubles (DDGS) as a component in shrimp feed.  Recently she decided to check back in with the researcher she interviewed for the story, Dr. Addison Lawrence at Texas A&M University, to see if there were any new developments with DDGSs.


Jensen says: “One example of an interesting story I wrote for Ethanol Producer Magazine is one published in 2012, about a project to produce domestic shrimp using distillers grains as a component of shrimp feed.  I enjoyed talking to Addison Lawrence, a Texas A&M University System researcher, so much that I wrote a follow up blog about the potential new market for distillers grains and Lawrence’s memorable personality and mannerisms.”


“Recently I decided it would be fun to contact him again, to find out how things are going with his quest to commercialize super-intensive stacked raceways, a shrimp production system he developed.  He shared a few details with me in a funny and enthusiastic email.  I didn’t expect any less.”


“He also told me that he still uses distillers grains in shrimp feed.  ‘I use up to ten percent inclusion levels depending upon the price of DDGS and the ingredients DDGS is replacing,’ he said, adding that he knows other shrimp producers are using it too, but he isn’t aware of how extensively it is being used or at what levels.”


“Efforts to commercialize his shrimp production system are moving along.  The technology is now patented in the USA, China and the European Union.  Lawrence would like to see a little faster progress, however.  ‘The first farm using this technology has the gestation time of an elephant [640 or 645 days],’ he said, adding that one should be in operation by this year or next.”


“Good things come to those who wait, I guess.  Perhaps it’s taking so long to commercialize the shrimp production system because it’s going to be a super-duper success.  I sure hope so, partially because it’s a good new market for distillers grains, and I wish Lawrence and his team the best of luck!”
