280 acres
Western Iowa Experimental Association

Alternative swine production techniques are studied at the research farm.
The association purchased the farm in 1946. In 2002, an additional 40 acres was given to the farm.
Gently sloping ridges and steep side slopes that gradually change to well-defined valleys characterize this region. Sloping soils are very erosive and require terracing, contouring and other conservation practices. Predominant soils are:
Ida:
6-30 percent slope, well drained, occurs on narrow divides and steep side slopes
Monona:
5-14 percent slope, well drained, occurs on ridges and s strongly sloping side slopes

Grazing beef cattle are fed condensed distillers solubles or syrup on research paddocks at the research farm.
Beef Cattle. Animal scientists study beef carcass quality to evaluate the effects of various grazing techniques and feedlot performance.
Swine. Research focuses on alternative pig production. The ISU Hoop Research Complex is located at the farm. Studies on animal density, pork quality, alternative feeds and wean-to-finish approaches are conducted with finishing pigs. Researchers include scientists from veterinary medicine and animal behavior.
Forage. Researchers are studying the possibility of improving the productivity of warm-season pastures by interseeding legumes. Researchers evaluate livestock performance on this pasture and in intensive rotational grazing systems to develop site-specific recommendations for the establishment and management of productive summer pastures in western Iowa.

The loess hills are an ideal site for studying Iowa’s native prairie plants. Research plots of native species are shown.
Beef research facilities include a 16-pen cattle feeding unit. Extensive pastures support grazing and forage studies. Deep-bedded hoop structures are used in the alternative swine production project. The Hoop Research Complex consists of three full-sized hoop barns that hold 150 finishing hogs each and three smaller research hoop barns equipped with pens for 10 pigs each.
