About Gourley Research Group

Gourley Limited Partnership (GLP) is owned 50:50 by the families of Gene and Maurita Gourley and Brian and Gina Smith. It is the original 140 acres owned by Gary and Georgianna Gourley (Gene and Gina’s parents) purchased in 1957.

In 2012, 5.2 acres were purchased by GLP near Stanhope, Iowa. Construction was started on a double wide 2,498 head wean to finish swine barn.

Gene, while working part time at Swine Graphics Enterprises directing the Nutrition and Research programs, designed the new GLP barn to conduct research and established Gourley Research Group LLC (GRG).​

In 2015 a second barn was built on the same site as the GLP barn. The new barn, a 2,498 wean to finish swine barn, was built by GRG and also set up to conduct commercial research trials. As of 2016 Gene has committed 100% of his time to Gourley Research Group.

In 2021, J&A was collaboratively purchased by Gene, Dr. Jason Ross, and Dr. Lance Baumgard, establishing Midwest Research Consortium.​

Higgins Nursery was built in 2020 by Will and Sawyer Higgins. GRG owns all of the research and feeding equipment that's used to conduct all research trials at the nursery.

From 2012 to 2023, the Gourley Research Group team has conducted and completed approximately 152 trials for companies all over the world.
