Which Corn Silage Hybrid Is Best for You?
A corn hybrid that’s best for grain yield may not be the hybrid that produces the best silage for j
livestock, according to research conducted by Cargill. w
For example, dairy cows need corn silage hybrids that can provide a high percentage of digest
ible fiber to help achieve top milk production and milk test. Beef cattle on a fattening program need
a daily ration with a high energy density for fast weight gain.

This chart compares Cargill hybrids
with each other. The rating scale is
9-Outstanding through
1-Substandard.
The above is based on the best infor
mation available in December, 1989.

State-of-the-art techniques used
include m-Vitro Digestible Dry Matter
(VDDM) to stimulate the ruman envi
ronment using rumen microbial fluid.
In-Vitro True Digestibility (VTO) was
used to measure whole plant ener
gy, In-Vitro Cell Wall Digestibility
was used to measure the amount of
digestible plant fiber available to
influence dry matter intake.

The Corn Silage Menu was developed to help you select
hybrids based on your livestock needs. We have evaluated our
hybrids and identified those that tested highest in key silage
traits. Use the Menu to make corn silage decisions.
Grain Yield rates hybrids on their grain production ability,
adjusted to 15.5 percent moisture within a maturity range.
Compare these ratings with silage tonnage and whole plant
quality ratings and you will see differences.
Silage Tonnage rates hybrids on their ability to con
sistently produce high tonnage yields within their maturity range.
Results of on-farm and research plots (80+ locations 1988-89)
were summarized and corrected to 70 percent moisture. This
enables us to analyze hybrids for silage tonnage in the same
manner we do for grain yield.
The following whole plant quality characteristics are important.
Digestibility rates whole plant digestion and energy density.
This is an accurate indication of a hybrid's total energy potential.
Intake Potential rates the fiber digestibility, a factor that
affects potential intake of a ration. This is essential for top milk
production.
Crude Protein rates the content of the whole plant to con
tribute crude protein to a ration.
