This CALS-sponsored research analyzed grass species, fertilizer rates and economics of pastures set aside (stockpiled) as feed for late fall into winter.

Researchers compared intakes and gains on different forages by grazing dairy heifers. They also measured methane emissions. Information generated by this project will further the base of knowledge about the use of stockpiling in the Upper Midwest.

Matt Akins of Animal and Dairy Sciences led this project from 2020-2022.

Additional researchers working on this project were Michel Wattiaux, Animal and Dairy Sciences; Erin Silva, Plant Pathology; Valentin Picasso Risso, Agronomy; Tom Kriegl, Emeritus, Center for Dairy Profitability; Jason Cavadini, UW Marshfield Agricultural Research Station; and Research Assistant Kate Wells, Animal and Dairy Science.
