Heat detection ‘stepped up’
RALEIGH, N.C., - The
pedometers that hikers use
to measure the distances
they walk, are being used in
research to detect estrus
(heat) in dairy cows. Dr.
Charles A. Kiddy, an animal
scientist with USDA’s
Agricultural Research
Service, has found via a
pedometer strapped to the
cow’s leg that she is much
more active when in heat
than when she is not.
Dr. Kiddy monitored the
activity of 40 dairy cows
wearing pedometers at the
Beltsville Agricultural
Research Center in
Maryland. The cows were
fitted with pedometers about
30 days after calving. Special
cases were designed to
protect the instruments and
allow for easy readng.
Readings were recorded for
all cows each time they were
milked.
An increase in activity
averaging four times that of

normal was noted during
estrus. Since the activity of
the cows as recorded by the
pedometers, tended to vary
little from day to day, the
increased reading during
estrus was easily detected.
When an increase in the
cow’s activity was noted in
the morning, she was bred
that afternoon; when her
activity increased in the
afternoon, she was bred the
following morning.
This system proved highly
effective in selecting cows
for breeding. In 92 per cent of
the estrus periods observed,
the cows were at least twice
as active as they otherwise
were.
Dr. Kiddy believes that
monitoring the activity of
dairy cows as a means of
detailing estrus would be
practical for commercial
dairy farms. Further
research is planned for dairy
cows milked under a variety
of conditions and climates.
Research will also be con
ducted on the use of elec
tronic equipment for
monitoring the activity of
cows.
Dr. Kiddy presented his
research before the 71st
Annual Meeting of the
American Dairy Science
Association.
