With Live Animals
“Sonar” Principles Used To Test
Back-Fat and Loin-Eye Depths
An electronic device that can
measure the sire of a potential
steak or chop in a live animal
may prove highly beneficial in
livestock marketing and breed
ing, U. S Department of Agricul
ture scientists say.
This device uses ultjasomcs
high-frequency sound waves
to determine the depth of back
tat and depth and width of loin
eye muscles m cattle and hogs.
These measurements are parti
cularly important in selecting
meat animals that produce a high
percentage of their weight in the
more desirable cuts.
Dr. Richard L. Hiner, head of
meat-quality studies tor USDA’s
Agricultural Research Service at
Beltsville, Md, says that ultra
sonic waves go through tissue
without harm to the animal.
The time needed for these
sound waves to pass through
bounce back fiom the interfaces
or borderlines between fat, lean,
rnd bone varies with distance or
depth The device uses these time
differences to deteimin the
depths of the vinous intei faces
‘ The nautical apparatus known
as Sonar acts on the same prin
ciple to find objects in water An
electronic device similar to the
one now being tested at Beltsville
used by manufacturing firms to
find flaws or faults in metals
( Prelimmaiy tests of the device
are being conducted by ARS ani
mal husbandmen and agucultural
engineers So far, comparisons of
„mmals measured by ultrasonics
before slaughter with actual mea
surements of the dressed caicas

curacy for the expenmental ap
paratus.
If cntmued tests prove the de
vice’s accuracy, it may be help
ful in selecting and grading hogs
and beef cattle before fattening
or slaughter It might be used by
feeders to separate groups of ani
mals into grades to insure proper
f'nish for slaughter, and thus im
prve the uniformity of marketed
livestock.
The appearance of live cattle or
hogs may not given a dependable
indication of the percentage of
fat and lean meat they will yield
when slaughtered Many animals
show meat-type chaiactenstics
outwardly, but are found on
slaughter to contain a high per
centage of fat and to yield little
lean meat
ARS scientists also see the use
of this type of electronic device
as a great aid in increasing the
effectiveness of bleeding pro
grams The increased accuracy it
would permit m the selection of
neat-type breeding stock would
i educe significantly the time
needed to produce superior lines
It would also result in a sub
stantial saving of time needed to
measure, probe, and judge in
dividual animals by prevailing
methods
This new ultrasonic device has
not proved feasible for sheep be
cause of their fleece Contact with
the animal’s skin is necessary for
accurate readings Such skm con
tact is fairly easy with cattle and
hogs.

they did not grow very much
throughout the year and some lost
weight This may have been due
to the poor-quality feed or not
enough food.
If full-fed from late spring un

deer will grow to about double
the usual Pennsylvania size, re

The average weight of legal
