Ventilation Problems
In little over a month dairy
barns without controlled ventila-
ton systems will start to give
trouble with condensation.
Sweating walls, wet window
stills and a general muggy atnos-
phere are typical conditions in
barns without good ventilation.
Animal health and production can
be seriously affected by the lack
of ventilation, since extremes and
rapidly fluctuating humidity and
temperature encourage respira-
tory diseases and stiff joints.
In the high humidity-moderate
temperature zone along the Mid
Atlantic seaboard, systems should
provide for at least 100 Gu. feet of
air per minute per cow, accord
ing to A. V. Krewatch, extension
agricultural engineer at the Uni
versity of Maryland.
He says the ventilating system
should have two or more fans.
This makes thermostatic control
easier, and also makes it easier
to reduce or increase the flow of
air to suit weather conditions.
KreWatch adds that the best
locations for fans and the neces-
sary intake openings will vary
with different barns.
1.-THE arrangement of the in
takes is most important" he
points out. "In general, however,
fans exhaust from near the cell
ing and the intakes are located so
as to bring air in without drafts
at the ceiling level. Approximate.
ly 20 square inches of intake
opening is required per COW for
the maximum number of cows
the barn is designed to stable.
Rats!
Through seven years of service
as University of Maryland extern
sion entomologist, T. L. Bissell
has constantly encouraged Mary
land farmers to rid their proper
ties of rats.
Get after those rats as soon as
one shows up on your place." he
has said scores of times. And
with this call to action he always
gave detailed control recommen-
dations.
BisSel recently had an opportu-
nifty to practice what he breaches
"a rat invaded the premises of
the man who has waged a 7-year
war on the rodent.
That was the wrong place for
the rat to make his home!
The invader made his burroW
under a concrete slab which is
the foundation for a rear porch
to the Bissell home, near the Uni
versity of Maryland.
ut is a mystery to me where
the rat secured his meals" the
entomologist says. "Our garbage
can is dumped every week and is
kept tightly closed all the time.
No scraps of food are dropped
outside and my next door neigh
bors are equally careful with
their garbage cans.
1--WE feed dogs out of doors and
occasionally someone leaves part
ly burned garbage, but food for
rats certainly is not plentiful ir
my neighborhood. Howev
there must have been enough
This proves you don't have tC
have an old tumble-doWn building
and trashy yards to attract rats
Evidently the rat was making {
good living from scraps of feeC
he cauld pick up, but he was glaC
to eat the oatmeal and warfarine
bait set for him. Bait was PLACED
in a box made of good incl
boards. The box had a small holt
at each end for the rat to enter
and locked top to keep out in
vestigative children. "Warfaril
