Michigan State University collaborated with Preston Farms to introduce high-oleic soybeans as an on-farm dairy feed ingredient, featuring oleic soybeans that improve milk components. In spring 2024, the family-run operation committed nearly 400 acres to the variety and began feeding the harvested soybeans to nearly 1,000 cows. Within days, the farm recorded higher milk fat and protein levels, increasing the value of their milk without adding complexity to daily routines.
MSU researchers, led by professor Adam Lock, had spent more than a decade studying how dietary fats influence milk composition, cow health, and farm economics. Their trials confirmed that high-oleic soybeans, especially when roasted on-site, can replace costly fat and amino acid supplements. Early on-farm adoption at Preston Farms cut purchased feed expenses by about 20 percent per month, while strong statewide demand quickly exhausted available seed supplies.
