Corn milling byproduct helps alleviate milkfat depression

A corn milling byproduct from the production of human foodstuffs is enriched with fiber and protein. That makes it a good candidate for offsetting some of the negative effects of high starch in lactating cow rations.

“In some diets with high starch concentrations, substituting these products for starchy grains could eliminate negative associative effects, resulting in improved NDF digestibility, increased feed efficiency and increased milkfat concentration,” Ohio State University dairy scientist Bill Weiss writes in the April edition of the Journal of Dairy Science.

When it comes to alleviating milkfat depression, the corn milling byproduct works best when it replaces some of the corn grain — not when it replaces forage and concentrate.
