“Cut all the branches off one
-side,” he said. “This will not hurt
the tree for timber, but no one
will want it for a Christmas tree,”
he said.
Natural reseeding is preferred
in farm woodlots, according to
Farrand.
If the farm woodlot has any of
the desirable species, larch, oak,
poplar, or white pine, natural
seeding can be accomplished by
allowing seed trees to stand while
clearing out undergrowth such as
dog-wood and other trees with no
commercial value. This will allow
the young seedlings access to sun
and promote their rapid growth,
says Farrand.
However, if the woodlot is to
be established from a bare field,
planted seedlings from a nursery
must be used. In such a case white
pine or larch is recommended.
The , plants should be planted
eight feet apart.
By planting eight feet apart,
the trees will prune themselves
naturally giving good long, knot
free sawlogs when the tree
reaches maturity.
In such a planting, the trees
will have to be thinned at the end
of about 15 years. This first thin
ning, Farrand says, will give a
good crop of pulpwood, thus cut
ting down part of the expence of
planting and caring for the trees.

Zinc Imbalance in Diet Causes
Parakeratosis in Swine, Tests Show
Scientists of the U. S. Depart
ment of Agriculture have demon
strated that a high-calcium, low
zinc imbalance m the diet causes
parakeratosis, a n'on-infectious,
mange-like disease of swine, and
that the disease can be cured or
prevented by adding zinc to pig
rations.
Although parakeratosis seldom
kills its victims, it seriously slows
down growth of the animals and
causes skin lesions and poor ap
petite? It has often been caused
inadvertently by feeding mineral
mixtures with too much'high-cal
cium bone meal or calcium car
bonate and little or no zinc.
By increasing the zinc content
of the pigs’ diet," scientists at
USDA’s Agricultural Research
Center, Beltsville, Md., complete
ly prevented parakeratosis in ani
mals not afflicted, and dramatical
ly cured diseased pigs.
USDA researchers J. W. Stev
enson and I. P. Earle recommend
that diets containing up to 1.0
per cent calcium be supplemented
with 50 parts per million of zinc.
Zinc can be obtained commercial
ly in the form of trace-mineral
supplements. Farmers should
check to be sure that the supple
ments they buy have a high
enough content of this vital min
eral.
In the Beltsville studies eight
lots of six pigs each were fed
diets varying in zinc and in cal
ciurfi.
A diet containing 32 parts per
million of zinc and 0 48 per cent
calcium, .produced mild to mod
erate parakeratosis in three of
six pigs. Increasing calcium to
0.67 per cent and to 1.03 per cent
at the same zinc level (32 p p.m.)
produced severe parakeratosis in
all pigs of two other lots.
Addition of zinc oxide to in
crease the total zinc content of
the pigs’ diet to 44 p.p.m. reduced
the severity and incidence of the
disease. Further increase of the
zinc level to 80 p.p.m. completely
prevented parakeratosis in pthei
animals, even with the calcium
level at 0.67 or 1 03 per cent.
Diets of the pigs were reversed
after 42 days to determine the
curative powers,of zinc and pos
sible carryover of its protective
effects. Animals previously get
ting small amounts of. zinc were
given additional quantities; ani
mals previously getting large
amounts were given less. Calcium
level remained constant.

the rapid therapeutic effective
ness of zinc. Improved appetite,
dramatic weight gams and dried
skin lesions were noted within
the first week in animals fed
more zinc. This was followed by
a gradual loosening and shedding
of the scurf and scabs that ac
cumulated during the active
stages of parakeratosis.
The shift from high to low zinc
in the -diets gave somewhat slow
er and less dramatic effects. First
definite lesions appeared 21 days
after the diet change. In 28 days,
parakeratosis had become esta
blished in one of three pigs on the
0.67-per cent-calcium level and in
two of three pigs on the 1,03-per
cent-calcium level.

About 91 per cent of these were

Early Lamb Estimates
Below 1956 Crop
The early lamb ciop in princi
pal producing States is estimated
at one per cent below 1956 bjj.the

and Texas, where breeding ewe
numbers on January 1 were down
six and 11 per cent, respectively,
were responsible for most of the
drop.
