leafy hybrid. The higher
starch digestibility was pre
sumably due to the softer
kernel texture of the leafy
hybrid. They found no milk
production difference among
hybrids or population treat
ments. Silages varied in these
trials by 2 units in NDF and
2.8 units in digestibility, yet
no milk response was noted.
These results are similar to
another trial recently con
ducted at the University of
Minnesota. Based on these
results, the authors suggested
that with regard to leafy hy
brids and normal hybrids,
hybrid selection could be

agronomic performance.
In another trial conducted
with a brown midrib (BMR)
hybrid and a normal hybrid,
they formulated rations to be
low forage with the normal
hybrid and high forage with
the BMR hybrid. In this trial,
the BMR diet produced simi
lar dry matter intakes even
though the BMR diet had 13
percent higher forage. The
high forage BMR diet pro
duced less milk, however,
compared to the low forage
control diet. In other trials at
Michigan State, BMR silages
produced 5 to 7 pounds more
milk per day when fed in sim
ilar diets. The Wisconsin re

Departments Of Agriculture, Environmental
Protection Sponsor Ethanol Workshop
GRANTVILLE (Dauphin
Co.) Agriculture Secretary
Samuel E. Hayes Jr. recently
welcomed guests to “Ethanol
for a Cleaner, More Pros
perous Pennsylvania,” a
workshop at the Holiday Inn
Harrisburg-Hershey.
The Department of Agri
culture, along with the Penn
sylvania Department of
Environmental Protection
(DEP) and the U.S. Depart
ment of Energy (DOE) Office
of Fuels Development, spon
sored the one-day workshop.
“High fuel costs and in
creased dependency on im
ported oil have sparked
“more research with various
types of diets is needed to op
timize the utilization of BMR
corn silage in dairy cattle
diets.”

renewed interest in the pro
duction of clean-burning al
ternative fuels for
Pennsylvania and its citizens,
businesses, and industry,”
Hayes said. “Ethanol is ex
tremely important as an agri
business product. This
workshop offers Pennsylva
nia agribusiness a look at the
21st century answer to
today’s need for developing
cleaner, environmentally
friendly fuels.”
The ethanol workshop,
funded by a Pennsylvania
Biomass Energy Grant
awarded by the Northeast
Governors Association, ad
dresses the manufacture of
traditional grain ethanol and
new forms of biomass ethanol
production.
Biomass ethanol is pro
duced from the fermentation
of varied cellulose sources.
Typically, plant residues
from harvested crops, such as
corncobs and stalks, cereal
straw, or seed hulls are the
most common source. Wood

and other herbaceous plants
can be processed into ethanol
as well.
“With today’s interest in
renewable energy sources,
and the increased national
concern about energy inde
pendence, ethanol produc
tion offers commonwealth
producers great opportu
nity,” Hayes said. “With
Pennsylvania’s abundant re
sources, producers have more
opportunity than ever before
to develop the com
monwealth’s ethanol indus
try.
“This is important to the
future of our nation’s trans
portation fuel supply because
ethanol production will be
possible in nearly every
region of the country using
low-cost resources such as ag
ricultural residues and wood
wastes.”
The United States uses
more than 1.7 billion gallons
of ethanol today, which is
blended up to 10 percent with
gasoline.
