Oats, Triticale, and Corn Winter Grazing Comparison

This field scale trial is being done with Sturgeon River Stock Farm, Onoway AB and was completed in partnership with Therese Thompkins, Agri-Trend. A comparison of oats, triticale and corn winter grazing was done. A write up will be in a future issue of Forage Views with the complete results and producer feedback.
