Feeding 2019 Corn Silage

A recent mycotoxin survey of corn harvested in 2019 shows 96 percent tested positive for at least one mycotoxin, while 61 percent of samples had more than one mycotoxin. Combine that with the potential for quality issues that may mean fewer pounds of milk per ton and producers need to get a handle on what they have in their piles.

To help producers evaluate their options, I-29 Moo University asked Dairy Specialist and Assistant Professor at Iowa State University Dr. Hugo Ramirez-Ramirez, shared what he is seeing from labs in the upper Midwest and what mitigation options producers have.

Ramirez will also share several other thoughts plus pile maintenance during feed-out.
