SUMMER COW CARE
All of us enjoy being
comfortable, especially on a
hot summer day; so do
cows! High producing cows
do their best when cool and
comfortable. One of the
coolest, most comfortable
spots on many farms could
be-a-V/ELL VENTILATED
'barn. In addition to
the
sun, it also protects them
from many of those very
annoying biting and sucking
flies found out of doors.
Keeping cows indoors on hot
days can offer other ad
vantages, too. It conserves
their energy and thus
reduces body heat. Coliform
mastitis flare-ups can be
reduced because there is less
opportunity for cows to he
down in muddy loafing areas
or wade belly deep in water.
There will be less trampling
destruction to the pastures;
cows can be allowed to graze
during the night.
If cows are outside during
hot days, be sure they have
plenty of shade, preferably
is a well-drained, breezy
location with water, salt,
minerals and other feeds,
such as hay, close by. If no
shade is available, consider
building an artifical shade to
provide 30-50 square feet of
shade per animal. A narrow
shade structure oriented
approximately north and
south will allow greater
opportunity for the rest area
to dry out as the sun shifts
from east to west.
GOOD VENTILATION
If cows are kept indoors,
good ventilation is essential
for good comfort. It will also
keep the bam drier and the
air cleaner, and thus help
prevent mastitis and other
diseases. A number of things
can be done to improve

ventilation. (1.) Open the
doors, windows and sides of
stables widely and avoid
blocking air flow. (2.) Open
the peaks, ndges, and gable
ends </ bams, or install a
large ventilation flue. (3.)
Use light-colored, reflective
building materials and
paints. (4.) Keep plenty of
height and slope to ceilings.
(5.) Use fans for positive air
movement--for replacing
stale, warm, moist air with
fresh, cooler, drier air;
about 500 cfm per cow are
recommended for summer.
(6.) Fans can also be used
to create comforting breezes
by blowing lots of fresh air
over the cows. These breezes
also help to discourage flies.
NEW FLY CONTROL
BREAKTHROUGH
Controlling flies also
contributes to cow and
human comfort-and to a
healthier environment and
better relations with the
neighbors.
Two new insecticides,
Ectiban and Atroban, have
recently received special
clearance for use as a
residual spray in Penn
sylvania to control flies m
dairy and livestock barns
and m poultry houses. Field
studies performed by Penn
State entomologists have
shown these two insecticides
to be very effective m
providing long lasting
control of flies, including
those flies which have
developed resistance to
many other products.
Hopefully, these two
materials will soon be
available.
Half the battle m con
trolling flies is to start early,
before the adult population
builds up and before egg
laymg activity gets into high
gear. If you already have a
STATE
DAIRY
HOGS
large adult fly population
before you start on a
residual spray program,
don’t expect overnight
results. It’ll take about two
weeks for fly eggs recently
laid to hatch out, and most
residual spray programs are
designed to work only on the
adult flies.
Basic to any good fly
control program is good
sanitation. To help prevent
fly breeding activity,
remove manure frequently,
especially bedded pack
manure and other damp
manure accumulating along
the corners of scrape alleys.
Dry manure or liquid
manure can not support fly
breeding activity, but damp
manure can.
Larvacides, when fed to
cattle, can help control the
development of fly larvae in
the manure. But, to be most
effective, these materials
should be fed to all cattle on
the farm, not just the
milking herd; otherwise, fly
larvae will continue to
develop in the untreated
manure around the farm.
Dust bags strategically
located m parlor exits,
feeding areas, shady areas
or rest areas can help
protect cows from annoying
face flies and thus helping
prevent pink eye. Baits,
livestock sprays, space
sprays, insecticide-contain
ing ear tags, etc. can provide
additional relief.
APPETITES AND
FATTEST
Fat tests and good ap
petites are hard to maintain
in summer. When cows are
hot, especially high
producing cows, they don’t
eat well, production drops,
and conception rates
decline. A cow’s body heat
increases as she digests
coarse, fibrous feeds; thus,
cows crave less-fibrous
feeds, and then, fat tests
decline.
Shade, good ventilation,
water, a “cool” ration and
palatable feeds are very
important. Shade and
ventilation were discussed
earlier. Water is your
cheapest feed, and it
“makes” milk! Be sure cows
have easy access to plenty of
fresh, cool water. Shade,
feed, salt and minerals
should be nearby.
Appetites can be enticed
by keepmg cows cool, having
good water readily
available, keepmg all feeds-

grains and silages-fresh and
palatable, and by feeding a
“cooler” ration. A “cooler”
ration is one that contains
more grain and the highest
quality forages available.
It’ll be a challenge to feed
sufficient fiber to maintain
desired fat tests without
curtailing production and
appetite. Using ration
buffers such as sodium
bicarbonate and magnesium
oxide may help. It may be
necessary to choose either a
higher test or high
production; it may not be
possible to obtain both. To
keep feeds fresh, it may be
necessary to offer smaller
portions and feed more
frequently, and to mix
smaller batches. A variety of
feeds and feed ingredients
may help entice appetites.
Proper balancing of the
ration is also essential for
good summer performance.
MASTITIS AND MILKING
Avoid stressing cows prior
to milking; don’t keep cows
standing or long periods of
time in a hot, crowded,
poorly-ventilated holding
area.
Mastitis organisms build
up rapidly under warm,
moist, summer conditions.
Good sanitation, good
ventilation, and proper
nutrition will help keep flare
ups under control. Pay
particular attention to stall
beds and rest areas; keep
them as clean and dry as
possible. Also, be con
scientious in drying off cows
udders before milking, using
individual cow towels to
wash and dry the udders,
teat dipping, dry cow
treating, milking infected
cattle last, etc. If cohform
mastitis is a problem, keep
cows away from wet, fdthy
areas and consider using a
teat dip such as Teat Shield
to protect the cattle from
coliform infections. If in
fected quarters are treated,
be sure to observe required
withholding times. The new,
very sensitive antibiotic test
for detectmg residues in
milk makes it doubly im
portant to withhold all
treated milk.
