Researchers from the University of Wisconsin-Madison examined 24 peer-reviewed journal articles published over an 11-year period to determine the effects of different corn silage harvest practices on dry matter intake and lactation performance of dairy cows.

Results from their meta-analysis were published this year in the Professional Animal Scientist journal, as well as presented in poster format at the 2012 Joint Annual Meeting of the American Dairy Science Association, held jointly with four other animal science societies.

Results show starch digestibility and milk yield were decreased for dairy cows fed diets containing corn silage with very high dry matter (greater than 40 percent dry matter), says Randy Shaver, University of Wisconsin-Madison extension dairy nutritionist. Starch digestibility and milk yield also were reduced for dairy cows fed diets containing corn silage with insufficient kernel processing.
