N E W RULES IN THE CATTLE G A M E
The rise in cattle feeding has brought about
a shift in the location of beef production and
in the source of feeder cattle — largely from
the western and Plains states to the Southeast
and Midwest. The U. S. Department of Agri­
culture’s Economic Research Service says that
these changes could be illustrated by using the
feeder cattle market as the basis for a board
game.
Several basic elements would be needed in
order to play the game. The playing board
would be a map of the United States, and the
playing pieces would represent ranches, feedlots, rail lines, and highways. By maneuvering
the pieces on the board, the players could get
a clear picture of how the livestock industry
operates and the changes that have taken place
since the 1940’s.
Perhaps the most obvious move to be played
is the shift in the importance of feeder cattle
producing areas, according to the ERS. For
example, in 1935-39 the western and six Plains
states combined accounted for three-fourths of
all the beef cows in the United States. Despite
an increase in actual numbers, the West had
only 60 percent of all beef cows in 1960-64.
Between the two periods, farmers in the South­
east and Corn Belt increased their stake in cow
herds and calf production.
With the reduction in cotton allotments,
southerners put some of their cotton land into
grass and improved the quality of their herds.
In the Corn Belt, high corn yields maintained
land values, and grain production was more

profitable than pasture. Since the feeding of
corn results in a substantial improvement in
beef quality, farmers found the grain to be
more valuable when marketed as beef. Conse­
quently, the practice of feeding grain to feeder
cattle in the Corn Belt has remained strong —
so strong that calf production from cow herds
in the Corn Belt areas, where grazing is most
profitable, has increased considerably.
The next move in the cattle industry game
is the change in the source of stocker-feeder
cattle production. The western states’ share of
output of these animals decreased from 70
percent in the midforties to 62 percent in 1962.
Feedlot managers want low-priced cattle that
are fast, efficient gainers. Southern animals
have been competing successfully with native
cattle for space in many western and inter­
mountain area feedlots.
Another move of the “pieces” in the game
since the 1940’s is the growth in the impor­
tance of concentrate feeding. Over the years,
the number of grass-fed cattle sold for slaughter
has declined gradually. The feedlot has become
an even more important outlet for young cattle.
In 1962, western producers marketed around
10.7 million head of Stockers and feeders.
About 9.6 million head went to cattle feeders
within the western region — mainly in Cali­
fornia, Kansas, Texas, Nebraska, Colorado,
and Arizona. Most of the remaining cattle were
shipped to the Corn Belt.
The development of trucks and improve­
ments in highways have been important in the

changing patterns of feeder cattle movements,
points out the ERS. Prior to 1930, cattle ship­
ments were largely via railroads. For all
practical purposes, the shipments were limited
to areas served by rail. Shipments from the
South to the Southwest, for example, were in­
direct and costly. Better highways and trucks
have permitted feeders to be shipped efficiently
in all directions.
Western Hemisphere Markets
A recent study on U. S. farm trade shows that
Canada is expected to remain the dominant
market for U. S. farm exports in the Western
Hemisphere during the next few years. Pros­
pects for expanding markets in Latin America
appear brightest in Mexico, Peru, and Vene­
zuela, according to the Economic Research
Service.
The report shows that the Western Hemi­
sphere takes a larger share of total U. S. farm
exports today than it did prior to World War
II. In 1963 the United States shipped nearly
$1 billion worth of farm commodities, or 19
percent of total agricultural exports, to West­
ern Hemisphere countries. In 1935-39, our
average sales to these countries were only $119
million, or 16 percent of worldwide exports.
The accelerated pace of U. S. exports to
Western Hemisphere countries in recent years
has been maintained only through stepped-up
sales to Canada. Shipments to Latin America
have decreased. One of the major reasons for
the decline is the loss of our Cuban market,
which amounted to around $145 million an­
nually in the pre-Castro regime.

States. The disease results in losses to Okla­
homa cattlemen of approximately $7 million
annually.
The new vaccine substantially reduces death
losses, as well as weight losses and other
damaging symptoms of anaplasmosis. Although
it does not always prevent animals from con­
tracting anaplasmosis, the vaccine greatly
reduces the severity of the disease. The Okla­
homa scientists have found that the vaccine
protects an animal for at least a year.
Two doses of the vaccine are required, ac­
cording to the experiment station. Cattle in
Oklahoma should be vaccinated between D e­
cember and May. The anaplasmosis vaccine
will be available through veterinarians in the
fall of 1965.
Live Oak Decline Widespread
in Texas
Widespread destruc­
tion of live oak trees in
Texas during the past
35 years has resulted
from what researchers
believe to be a specific
fungus, points out Dr.
R. S. Halliwell, Assis­
tant Professor in the Plant Sciences Depart­
ment of Texas A&M University. Dr. Halliwell
says that live oak decline was first observed
in the vicinity of Austin in 1933. Since that
time, the “disease” has spread to most of the
live oak habitats of Texas.

W orld's First Anaplasmosis Vaccinel

Occurrence of the disease in many new areas
during the past year has caused growing con­
cern among both tree owners and researchers.
The disease shows little preference as to local­
ity or environmental conditions. It affects both
cultivated and forest trees, young as well as
old trees, trees on both acid and alkaline soils,
trees on sandy and heavy clay soils, and trees
in humid and dry climates.

Scientists with the Oklahoma Agricultural
Experiment Station have developed the world’s
first successful vaccine for anaplasmosis in
cattle. Anaplasmosis, a blood disease, is the
fourth most costly cattle disease in the United

Yellowing of leaves is the first outward
symptom of an infected tree, according to Dr.
Halliwell. Leaf yellowing may occur on certain
branches or on the entire tree. If the whole tree
is affected, it usually dies within a week o r

Department of Agriculture, Washington,
D. C. 20250.

The specialist says that no satisfactory con­
trol for live oak decline has been developed
as yet. However, live oak tree owners can
reduce the chances for their trees to become
infected by removing all infected trees im­
mediately after detection and by maintaining
the trees in a healthy condition through sup­
plying sufficient amounts of moisture and plant
nutrients.

Dairymen Can Overcome
"Summer Slump"

More Efficient Tomato Packing
By making minor changes in their packing
lines, many packinghouse operators can pack
tomatoes at lower costs, reports the U. S.
Department of Agriculture. Moreover, the
improvements would help hold down retail
prices, which reflect marketing costs.
Marketing researchers with the Agricultural
Research Service say that the recommended
changes in the tomato packing systems could
reduce handling costs at some packinghouses
by as much as $7,000 a year. Examples would
be packing plants handling an annual volume
of 200,000 60-pound containers or 300,000
40-pound containers. Although they are based
on systems used in Florida packinghouses, the
improvements apply to other states, according
to the ARS specialists.
In the Florida studies, the most efficient
tomato packing system was operated by 17
workers, who handled a volume that would
require as many as 31 workers using less-effi­
cient procedures. In the system, check weigh­
ing was done at the end of the packing line
rather than at each packing station. In addi­
tion, a drop-side-bin packing method improved
slower stations, and a backstop improved
faster, open-spout stations. A container chute
and a 90-degree conveyor were also used at
each station.

Good dairy management during hot weather
can maintain August milk production near the
May level, reports the U. S. Department of
Agriculture. Dairymen have long complained
about a “summer slump” — generally con­
sidered a result of hot weather. However, re­
search indicates that reduced milk yield is not
primarily due to heat exhaustion in cattle.
After exposing dairy cows to a variety of
temperature-humidity combinations in an arti­
ficial climate laboratory, Dr. Robert E. Mc­
Dowell, Dairy Scientist with the Agricultural
Research Service at Beltsville, Maryland, has
found that cows can adjust exceptionally well
to the direct effects of heat and humidity. He
says that the more trials they run, the more
convinced the scientists are that milk flow
tends to decrease largely because of summer­
time problems which are the indirect — and
not the direct — result of hot weather. Dr.
McDowell recommends that herd managers
take the following steps to overcome problems
brought on by hot weather.
• Provide sufficient high-quality feed and
avoid mature pasture grasses.
• Keep animals from having to travel far
to feed, water and shade.
• Allow grazing only during the cooler
hours of the day.
• Control biting insects, which are worse
during the late evening and night.
• Provide adequate shade and plenty of
fresh, cool water.
Milk Cooling Time
Agricultural Research Service scientists have
completed the first stage of research to deter­
mine how fast milk should be cooled in a
bulk tank. Milksheds regulate the cooling rate
of milk, usually specifying that it must be

lowered to 50° Fahrenheit in 1 hour. Although
no research results are available to support
the 1-hour cooling period, the time is con­
sidered to be within a safe limit.
Fast cooling of milk is costly, however, and
may cause a portion of it to freeze, resulting
in possible harm to the flavor. Slow cooling
also can be dangerous. Bacteria multiply much
more rapidly at higher temperatures, and if
cooling is too slow, the milk can deteriorate
noticeably.

to produce low-calorie pecans, walnuts, al­
monds, Brazil nuts, cashews, and other nut
meats. The shelled nuts are brought to the
proper moisture content and placed in a hy­
draulic press to remove most of the oil, which
constitutes about one-half of the peanut’s
weight. The pressed kernels return to their
original shape and size when soaked in water.
Salt, sugar, spices, or other flavoring can
be added to the peanuts during the ’’reconstitu­
tion” period. After drying, the low-calorie nuts
are ready for eating, for roasting, or for use in
candies and other foods.

Dietetic Peanuts
Peanut fanciers with weight prob­
lems may have less cause for con­
cern in the future, points out Secre­
tary of Agriculture Freeman. A new
low-calorie peanut can now be pro­
duced by a process that removes 80
percent of the oil (about threefourths of the calories), leaving in­
tact the original good flavor and
high protein content. When it goes
into commercial production, the product
should open up new markets for peanut
farmers, whose production has been increasing
faster than the public’s appetite for peanuts.
Exploratory studies have shown that the
same process used with peanuts might be used

In order to use the CMT, the dairyman
mixes a small amount of milk from each
quarter of a cow’s udder with an equal volume
of a chemical reagent. The resulting degree
of gelling is rated by several categories. These
categories reflect roughly the number of udder
tissue cells in the milk — an acceptable
method of expressing the extent of udder in­
flammation.
ARS specialists consider the CMT to be
dependable for showing whether the milk
contains a high number of tissue cells but say
that intermediate numbers cannot be inter­
preted accurately. The specialists suggest that
the dairyman keep a day-to-day lookout for
abnormalities in the cow’s milk. Clots, flakes,
blood, and wateriness in a milk sample require
a careful follow-up check on the cow’s health.
