Heart Activity Developed by USDA
Radio System of Recording Stock
An experimental system of re
cording the heart pulsations of
faim livestock by radio was de
scribed by U S Department of
Agriculture engmeets at the an

The system uses a sub mima

useful to biological scientists as
its more refined counterpart, the
electrocardiograph, is to medica
scientists.
The 'radio cardiograph was de
signed bv J C Webb, Lowell E

sock of the Farm Electrification
Research Laboratory, Agncul
tural Engineering Research Dm
sion of USD As Agricultural Re
search Service It was built, in
part, under contract with the U
S Air Force and with the coop
eration of USDA animal husband
men.
The system is built of com
ponents available in normal com
mercial outlets but used with
limited modifications It is divid
cd into two parts a transmitting
section and a receiving and re
cording section
The transmitting section con
sists of a transmitter and a low
level amplifier with an adjust
able gain of 60 decibels and a
frequency response of 3 to 4,000
cycles withm two decibels. The
transmitter operates on a fre
quency of 166 475 megacycles
and has a range of 150 feet
The receiving and recording
section consists of an FM receiv
er, an oscillograph and a heart
rate meter.
The radio cardiograph can he
used on both animals and hu
mans but there are certain limi
tations to its use, according to
the engineers Although it will
give excellent results on sub
jectts while they are moving
around, their movements should
be restricted to walking or simple
limb movements If muscle
movement becomes too intense

More Market Seeking Needed, Fat
Studies Desired, Committee Says
Research to expand present
markets for meat and meat pro
ducts, especially hides, to study
(he rble of animal fat in human
nutrition, and to develop more
efficient livestock breeding prac
tices was urged by the U. S De
partment of Agriculture’s live
stock Reseaich and Marketing
Adusaiy Committee at its annual
meeting m Washington, Feb. 17-
t 9
In the aiea of marketing re
search, committee members call
ed for a study to develop new
markets for hides and leather.
This work would provide an
economic analysis of trends in
leather use and the effect of
synthetic matenals.on traditional
leather markets, the committee
said
New research to evaluate qual
ity in poik, new studies of the
use of antibiotics, radiation, and
inert-gas packaging to preserve
fresh meats, and consumer-opin
ion anal} ses of attitudes and pre-
Imences concerning both meats
and leather were also cited as
high-priority needs in marketing
icsearch The survey of opinions
on leather, committee members
noted, should put particular em
phasis on leather in wearing ap
pal el and attempt to determine
consumer attitudes regarding
maintenance and care of leather
the cardiac voltage will be com
pletely blocked out
Placement of the electrodes
is very important in receiving a
good cardiac signal. Used in ex
penments with swine, the record
mg apparatus is carried on the
backs of the animals.

Expanded swine and beef
breeding programs and prelimi
nary work on a national swine im
provement plan similar to the
Dairy Herd and Paultry Impiovo
ment Programs now underway are
the most urgent production-re
search needs, the committee said
Beef-breeding research has
been underway for a number of
years, and many stocks are now
reaching a stage of development
where thorough performance
tests in top crosses and line cros
ses are needed to realize the ful
lest benefit of the work, accord
ing to the committee.
In swine breeding, more studies
of meat-type hog production are
remred Besides backfat thick
ness, factors directly concerned
with amounts of lean muscling
need to be given special study
Committee membebrs also urg
ed more research on the develop
ment of new chemical and envi
lonmental measures to control
parasites and pests of food ani
mals
The role of fat in human nutri
tion should be studied as speedily
as posible by USDA’s home econo
mics researchers, the committee
indicated Knowledge of the rela
turn ship of amounts and types of
fat to the metabolism of another
nutrients and desirable upper and
lower limits of fat intake are espe
cially needed. Now, comprehen
sive data on the fatty-acid content
of foods is also a top home-econo
mics research need, the commit
tee said.

more investigations of meat com
position and microbiology related
to processing, and (2) expanded
studies of fal-denved products
suitable for industrial use
Marketing service work regard
ed by the committee as meriting
high priority attention includes
(1) expansion of the uarterly ic
poits of cattle on feed, now is
sued in 13 states, to include a
number of additional cattle-feed
ing states, and (2) expanded
analyses of data on measurements
ana yields of beef cuts to dctei
