Heavy rainfall this summer and fall has left hayfields and ditches flooded, leaving bales at risk for mold and other issues. The more water covering the bales, the more damage or loss of nutrients occurs. “In a low-lying area where water stands, that water infiltrates into the bale and wicks up into higher areas of the bale,” says Karl Hoppe, livestock systems specialist, NDSU Carrington Research Extension Center. “More than likely there is going to be a lot of mold in those bales.” Hoppe encourages livestock producers to monitor feed grain for ergot and vomitoxin. “Know what type of toxin is there and how to handle it.” Listen to the interview.
