How Does Your Herd Compare?
STATE COLLEGE (Centre Co.) This data is pulled from Pennsyl
vania DHIA’s mainframe computer each week. It is a one-week summary
representing approximately one-fourth of the herds on test, as they are
tested monthly.
These data are valuable from a business management standpoint and
can be used for comparing your operations to the averages from almost
1,400 herds across the state.

Keep
Cows Cool
ESTON MARTZ
PSU Ag Info Services
UNIVERSITY PARK (Centre
Co.) Keeping your dairy cows
cool and comfortable during the
dog days of summer can help
ensure that their milk production
remains steady.
"Good ventilation for dairy
cows is critical during hot weath
er," said Stephen Spencer, profes
sor of dairy and animal science in
Penn State's College of Agricul
ture. "When temperatures rise and
the cows arc uncomfortable, they
may respond by reducing their
feed and dry matter intake. Subse
quently, their milk production
falls, loo."
Spcnccr said that sometimes it is
difficult to tell whether heat is
making a cow uncomfortable.
"Cows seldom exhibit obvious
symptoms of poor ventilation,
except in brutally hot weather
when they begin to pant," he said.
"Changes such as a reduction in
dry matter intake can be subtle and
hard to detect until milk pro
duction falls off."
Instead of waiting for obvious
symptoms to appear, make sure
your cows' quarters are cool before
they become uncomfortable.
"Get stagnant air out of the bam
and let the cows breathe fresh air,"
Spencer said. "It's easy to use fans
to augment your present ventila
tion system, and it's virtually
impossible to move too much air

into the bam."
One way dairy farmers can use
fans to keep cows cool is by turn
ing their bam into a "wind tunnel."
"Placing fans at intervals
throughout the bam and opening
the doors at either end can create a
tunnel effect," Spencer said. "It
moves the air through the bam and
helps keep the cows comfortable."
This "wind tunnel" effect can
This Report’s
PIP. That’s short for Potential
Identification Problems, and it’s a
new report being sent to members
on official programs every spring
and fall. What’s it used for? Simp
ly to alert members to possible
identification problems with some
of their animals before the semi
annual USDA genetic evaluations
are done. That will give members
the chance to correct those ID
errors that could prevent their ani
mals from being evaluated, or pre
vent their records from being used
in bull proofs.
When you receive the report,
which looks like the one shown
below, check the information
listed and if there are errors, let the
records auditors in State College
know right away. Just call
800-344-8378 (800-DHI-TEST)
and talk with Gary or Dan. They’ll
be glad to help you.

"If air is moving steadily
through the bam, it will help
reduce fly problems," Spencer
said.' Flies don't like to be in the
wind.
"Make sure free-stall bams have
adequate side ventilation," he said.
"Side panels usually are too small
to provide adequate air
movement."

Spencer said dairy farmers may
want to consider new ventilation
ideas such as curtain walls for free
stall bams.
"A number of farmers have
replaced the side walls of their
bams with curtains, which allow
the whole side of the bam to be
opened for ventilation," he said. "It
makes a remarkable difference in
the air and temperature conditions
inside the bam."
