The 2020 growing season brought challenges to Iowa corn growers. Drought and the August derecho wind damage are the two primary events that may have impacted corn quality and feed value.

This publication is intended for swine producers who grow corn and manufacture feed on-farm, feed mills, and nutritionists.
