Standardized protein
BELTSVILLE, Md. - An
extensive study of the four
common methods used to
determine protein in
solubility indicates the need
for a more accurate stan
dardized test, says Dale R.
Waldo, an animal scientist
with the U.S. Department of
Agriculture’s Science and
Education Administration.
Protein insolubility tests
Who runs our schools?
HARRISBURG - The
Pennsylvania School Boards
Association has announced a
statewide series of public
forums to be held m 10
geographic locations
throughout the state.
Hooked rug
course starting
MEDIA - Learn the art of
rug hooking. Dyeing of wool
to achieve the exact colors
you need will also be taught.
This workshop will begin on
September 21 and meet on
Sept 28, Oct 5,12,19, 26, Nov
2,9, 16,' and 30 m the Toal
Building Auditorium from 10
a.m. to noon.
The $2O. fee is due Sep

Maryetta Duffner, Toal
Building, 2nd and Orange
Streets, Media, Pa. 19063.
This mdudes the printed
materials. Mary Tilson will
be the instructor.
When normal conversation
is difficult to hear clearly at
a distance of three feet or
less, the sound level may be
hazardous to human hearing
ability, warns the Beltone -
Crusade for Hearing Con
servation. Persons working
m such environments should
be provided with protective
ear devices, the Crusade
officials add.

are used to determine the
amount of protein that is not
broken down in the rumen
and thus is available for use
directly by the animal. Feed
manufacturers need these
tests to determine the
available protein in a par
ticular feed, and farmers, in
turn, need these analyses in
providing proper nutrition
for their livestock.
beginning with a meeting
here at the Pennsylvania
State Museum on Sept. 12.
All meetings begin at 7:30
p.m. and will end by 9 p.m.
The meeeting in
Harrisburg is for the
Harrisburg area, including
southeastern and south
central portions of the state.
Other meeting times and
places may be obtained by

School Boards Association,
412 North Second Street,
Harrisburg, Pa., 17101,

The forums are intended to
engage the public in
discusssion around the topic
“Who Runs Our Schools?”
Meetings are open to the
public.

At the Beltsville
Agricultural Research
Center in Maryland, Waldo
and animal scientist H.
Keith Goering analyzed 15
feedstuffs: Oats, wheat
middlings, barley malt
sprouts, com gluten feed,
wheat bran, soybean meal,
cottonseed meal, , barley,
dehydrated alfalfa, com,
com hominy, com distillers
dried grains, barley brewers
dried grains, beet pulp, and
corn gluten meal. A
minimum of ten samples of
each feedstuff were tested.
All feedstuffs were collected
from commercial sources.
To determine protein
insolubility, ground samples
of each feedstuff were
placed m the following:
Boiling water for one hour;
autoclaved rumen fluid at
39°C for six hours; 0.1
concentration of Burrough’s
solution at 39°C for six
hours; and 0.15 molar
sodium chloride at 39°C for
six hours.
“The results of our study
indicate that these tests vary
widely in ability,to predict
protein undegradabihty. The
correlations between
methods were low and ex
tremely variable,” says
