McNay Research and Demonstration Farm
Southern Iowa soils and topography are conducive to pasture and beef cattle. The ISU McNay Research Farm is located in this region.
The McNay Research Farm has a beef cow herd used for research purposes. The cows and replacement heifers are grazed on predominantly improved cool-season grass pastures. There are approximately 300 spring-calving cows and 100 fall-calving cows. Grazing season was set at mid-April to mid-October or about 6 months (180 days).
