Nutrition group critical of McGovern report
ROSEMONT, 111 - A
recent statement by the
board of directors of the
prestigious Society for
Nutrition Education (SNE)
takes specific exception to
the “Dietary Goals for the
United States,” proposed by
Senator McGovern’s Senate
Select Committee on
Nutrition and Human Needs.
Similar to the stand by the

MADISON, Wis. - Glucose,
when infused into the fourth
or true digestive stomach
(abomasum) of cattle on a
high forage diet, improves
the utilization of acetic acid,
says Dr. Henry F. Tyrrell,
an animal scientist with
USDA’s Agricultural
Research Service. More
efficient utilization of acetic
acid can mean increased
weight gains in cattle on
forage diets.
Previous research at the
Belstville Agricultural
Research Center in
Maryland showed that cattle
utilize acetic acid, a major
end product of digestion,
more efficiently when it is
part of a grain diet, than
Grain production
surveyed
HARRISBURG - Penn
sylvania’s 1977 grain com
production is expected to be
10 per cent short of last year
at 93.2 million bushels ac
cording to the Crop
Reporting Service. Based on
July 1 conditions, this is the
result of 1,165,000 acres
intended for grain harvest
and a yield indicated at 80
bushels.
The commonwealth’s
winter wheat crop is still
expected to total 7.02 million
bushels, unchanged from the
June estimate and 26 per
cent below last year. This
would be the state’s lowest
recorded wheat production.
Production of oats from
the 350,000 acres for harvest
is estimated at 15.8 million
bushels or 14 per cent below
last year. The indicated yield
of 45 bushels is off five
bushels from last year.

Association, SNE’s
statement says that the
evidence on which the
“goals” are based is
“limited to epidemiological
data and food disappearance
studies which result in
population needs rather than
individual goals.”
Research Council - or an
McGovern’s report was expert task force comprising
published earlier this year representatives from the
and generated considerable Food and' Nutrition Board,
aids forage digestion
when it is part of a forage
diet. Cattle on forage diets
absorb a higher proportion of
energy as acetic acid, but
apparently the acetic acid
cannot be utilized as'well,
limiting the rate at which
cattle gain weight. Scientists
believe that some factor in
grain improves acetic acid
utilization, and they are now
looking for that factor.
Tyrrell infused six
yearling Holstein heifers on
a high forage diet with either
acetic acid or glucose. There
was little utilization of
metabolizable energy (ME)
from the acetic acid, but 60
per cent of the ME of the
glucose was used. When he
infused the acetic acid and
forecast at near seven
million bushels, would be a
ten per cent increase over
1976. Acres for harvest are
down 2,000 at 145,000 but this
is more than offset by a five
bushel yield increase to 48
bushels.
Rye production as in
dicated at 392,000 bushels is
eight per cent above last
year due to a higher yield of
28 bushels.

glucose together, the ME
from the mixture was used
as efficiently as was glucose
alone, indicating that it is the
glucose that is necessary for
efficient use of acetic acid.
In fact, a small amount of
glucose added to the diet
produced changes similar to
those that would have been
produced from a large
amount of grain.
Although glucose cannot
be fed directly to cattle,
cattle are able to synthesize
it from substances called
glucogenic precursors.
Increasing the amount of
glucogenic precursors in the
diet may help cattle utilize
acetic acid more efficiently.
More research is needed,
but Tyrrell hopes that fur
ther studies will lead the way
to improving the efficiency
of forage diets for growing
and finishing cattle.

National Insitutes of Health,
and 'Voluntary and
professional organizations -
could review, evaluate,
document, and elaborate on
the goals suggested by the
staff of the Senate Select
Committee. A scientifically
supported presentation of
current knowledge and
opinion regarding diet and
disease, indicating gaps and
research needs, coming
from such a group, would
give stronger support and
justfication for programs to
encourage modifications of
dietary habits in line with the
stated goals. Recom
mendations should represent
achievable goals which are
modifications rather than
replacements of current
practices.
“We believe some ad
ditions should be made to the
goals as published. For
example, obesity is a major
health problem, one related
to increased risk from
several other diseases, e.g.,
hypertension. Obesity is
directly related to food in
take in excess of energy
output needs. For this
reason, we feel that general
goals for calorie con
sumption are important.
“SNE would be glad to
cooperate with the Senate
Select Committee in refining
the dietary gods so that they
can begin to be realistically
implemented in nutrition
education -ograms.”
