Livestock is one of the top consumers for Iowa corn and distillers grains (DGs), a co-product from ethanol production.
According to the 2014 Iowa Ag Economic Contribution Study, which uses the 2012 Census of Agriculture information, livestock farming is a significant part of agriculture's economic contribution. Statewide output attributed to livestock production and further processing is just under $31.6 billion and is responsibile for 122,764 jobs. 23 of Iowa's counties derive at least one-fifth of their total agriculture and agriculture-related jobs from the livestock and meat processing industries.
Because livestock is an important corn customer, the Iowa Corn Promotion Board and the Iowa Corn Growers Association provide financial and in-kind support to many livestock initiatives such as the U.S. Meat Export Federation (USMEF) and the Coalition to Support Iowa's Farmers (CSIF), as well as various livestock research projects through Iowa State University.
