DIPPING SHEEP FOR scAB
Prof. Thomas Shaw Gives Some Sug-
gestions for the Treatment
of Sheep.

The dipping OF 81 .ep is practiced to
AZ, them from ticks and also from
tn. ssence of the scab mite. The
proprietary dips are used for the pur-
pose as a rule, although the bureau
of animal industry still favors the use
of the lime and sulphur dip, although
much evidence has been brought for
ward to show that 1t Injuries the wool.
If applied just after shearing the
sheep, this result would not follow.
Prominent among the proprietary dips
are chloronaptholeum zenoleum and
certain preparations with tobacco as
the principal element in their potency.
The following is the fomula for
making the lime and sulphur dip:
Ta4e eight to eleven pounds of un-
s'aked lime and add enough water to
slake the lime, sift into this three
times as many pounds of flower of sui
phur as there were pounds of lime at
the outset Boil the mixture from two
to three hours. adding water when
necessary. Pour the mixture into a
tub. vat or barrel that 1t may be
drawn off through a spigot without
sediment When using this dip, 1t is
greatly important to keep the sedi-
ment out Of the mixture.
| The common form Of the infection
known as sheep scab causes greater
loss to the sheep industry in the Unit
/ ed States than any of the external
parasites which prey upon them. 1t Is
produced by minute insects, many of
which are too small to be seen with
/ ont the aid of a microscope. Usually,
| however. If tuft of wool Is pulled
out near the edge of the infected part.
| little moving objects may be noticed
| by the naked eye near the base of the
wool ibers, or among the scales adj
| herring to them. They irritate the
skin ny biting, this causing an infam-
nation which produces an itching and
gives the sheep no rest. The inflam-
nation is accompanied by scab forma-
ton, under which the mites live.
The rubbing of the sheep carries the
s"ob to new centers, and thus the
work of torment is frequently carried
on simultaneously on different parts
Of the body. The wool soon becomes
taggy and finally drops off in various
places.
The remedy. as intimated, is dip
ping The sheep should be dipped
twice with an interval of eight to ten
days between the dippings. The sec.
ond dipping is given to destroy any
mites that may have hatched out sub
sequent TO the first dipping. AS soon
rs dipped the sheep should be removed
from their old surroundings and pas
ture grounds for a period OF at least
90 days. The eggs hatch in two OF
three days after they have been laid
When the hocks are small, says the
Orange Judd Farmer, the dipping may
te done In water-tlght box made fol
the purpose, into which the sheep are
lifted. They may also be dipped In
galvanized watts made for the purpose
When large lots are to be dipped, how
ever, tanks made for the purpose are
necessary, through which the sheer
are made to swim. and from which
they are made to emerge at the farther
end. The construction Of these cannot
be given to this paper. Sheep bough
at the stockyards may usually be dip
ped there. but II ought TO be remem
bered that for scab one dipping Is no
enough. The preparation of the pro
prietary dips Is outlined in the direc
tons that accompany them.
