Nuts and Bolts of Corn Silage Quality

Dr. Hugo Ramirez, Assistant Professor at Iowa State University, discusses silage fermentation, factors affecting silage quality and animal response to improved corn silage quality.  Below are the 5 C's of corn silage quality recommended by Dr. Ramirez.

    1. Content of Dry Matter - Maturity
    2. Chop length and kernel processing - chopping length should be 19 mm or 3/4 inches; kernel processing should be 2 mm or tighter
    3. Compaction - packing; the goal is at least 15 pounds dry matter per cubic foot
    4. Covering and sealing - cover and seal as soon as possible, use oxygen barrier and black and white plastic cover
    5. Care and management at feed-out
