The primary goal of making corn silage is to preserve as many nutrients in the corn plant as possible, to produce a feed that is acceptable to cows, and to minimize any risks associated with feeding the silage, says Bill Weiss, dairy extension specialist at The Ohio State University.
In the July 2012 Buckeye Dairy News, Weiss discusses recommendations for making corn silage during drought conditions, including:
Chopping at the correct dry matter concentration.
Using a proven inoculant.
Checking for nitrates.
Chopping at the correct particle length.
