Dry Corn Silage Application

December 1, 2018

By Lisa Davis, MS – Dairy Product Manager




In some years, growing and harvest conditions result in a corn silage crop that is drier than optimal (>38% DM).  Dry corn silage presents several challenges to lactating cows and can lead to variable or reduced intakes and milk production.  Below is a brief summary of the challenges of dry corn silage:


Concern Effect QLF Application
Reduced NDF Digestion  (by 23-33%)

Reduced Starch Digestion (by 6-10%)

Reduced Rumen-available CHO

Reduced Rumen bug growth

Reduced Rumen N utilization, & efficiency

Reduced DMI, Milk

Provide sugars and degradable protein to increase rumen microbial growth & efficiency

Increase NDF Digestion & VFA production

Increase DMI, Milk, & Milk Components

Deliver nutrients & specialty additives to complement precision feeding & enhance efficiency

Poor Corn Silage Stability Aerobic Fermentation 

Extended heating

Increased Yeast & Mold Growth

Reduced Nutrient content

Reduced TMR Stability

Reduced DMI & Milk Fat

Provide concentrated source of nutrients to TMR

Reduce ration sorting 

Increase TMR palatability, &  daily intake consistency

Deliver TMR Preservative to extend bunk life (MYCO CURB®, Ultra CURB®)

While QLF Liquid Supplements can help improve rumen efficiency when dry corn silage is fed; don’t forget that supplemental sugar increases fiber digestion of high-quality forages also!  Please contact your QLF representative for more information.
