It appears that grain con
taining up to 18 percent
moisture can be dried ade
quately by using a solar
heated-air system even
when the sun shines only 3.-
5 to 6.5 hours a day.
Because of faster drying,
a solar-heated-air setup will
uSe only about half the el
ectricity that is needed for
moving unheated air. This
will be true whether air
flow is continuous or fans
are controlled to operate on
ly when the relative humid
ity is less than 85 per cent.
Where in-storage frying is
used, it is unlikely that any
profit can be made by in
creasing the flow of solar
heated air above that norm
ally recommended for un
heated air systems. A great
ly increased air flow usual
ly results in much faster
drying, but adds to the cost
for electricity.

For lean Hogs
Selection is Effective. Method
Four generations of selection for high and low fatness
m Duroc hogs show a widening lean-to-fat ratio, indicating
that selection based on backfat thickness continues to be
highly effective in changing carcass composition. Backfat Is
measured by a lean-meter which makes use of the fact that
fat tissues don’t conduct electricity as well as lean tissues.
Backfat thickness in the
Duroc foundation stock av
eraged 1.49 inches. This in
creased about 21 percent to
1.82 inches in the fourth
generation animals specially
bred for high backfat (high
line), and decreased about 17
percent to 1.25 inches in pigs
bred for low backfat (low
line). Selection in Durocs
lias so far been somewhat
more effective in increasing
backfat thickness than in de
creasing it.
Selection for high and
low fatness has been carried
through two generations in
Yorkshire pigs, with backfat
thickness averaging 1.26 in
ches in the foundation stock.
This increased 5 percent to
132 inches in the second
generation high-line pigs,
and declined 5 percent to 1.-
20 inches in the second gen
eration low-line pigs.

Similar investigations are

Along with changes in

Durocs continued to decrease

These pigs averaged 29.7

, Manti. Utah— (April 19)—
Ninety-nine percent control
[of cattle grubs, five months
control of lice and improved
wintering, summarizes the
Utah Range Cattle Grub Con
trol Project. These results
were reported on the basis
of a recent spot check of the
9,000 cattle involved.
Approximately half of the
cattle were sprayed with a
systemic grubicide, at the
time" they were brought in
for the winter. At the same
time, all of the cattle that
wintered in the same areas
were treated. The remainder
of the cattle in the cooperat
ing associations were left un
treated.
A careful check in each
herd of both the treated and
untreated cattle early in Ap
ril disclosed that those spray
ed had an average of only
19 grubs per 100 head. Check
animals included cows, and
calves and yearlings of both
sexes.
In addition, none of the
treated herds showed evi
dence of lice five months af
ter treatment, while numer
ous lice were noten in sev
