ONE MUST COOPERATE
Louisiana Is the Only State Using
the TWenty-one Day Dipping
Periods.

Some of the questions most FIRE
euently asked on tick eradication are
answered below by Dr.. ". H. Dalrynl-
pie, Of the Department 0; Veterinary
Science, Louisiana State University:
Why is it necessary to dip cattle
every - days during the season to
get rid Of the ticks?
Answer. During the warm season
Of the year. the average time Tegu!r-
ed by the tick to develop, from the
small larval, or seed tick, after al
tachirg to cattle, until the large fe-
male tick natures and drops TO the
ground 10 lay her egg, is about 90
days. But while % days may be the
average, many ticks mature earlier
than that time Consequently II has
been found that the 2l-day dipping
periods do not catch the earlier-1na-
turing ticks, which drop off and keep
on making more ticks, thereby delay
ing the final results On the other
hand, by dipping cattle every IA DAYS,
all Of the ticks that become attached
to them il the intervals are killed,
because none of them mature and
drop off before a days
How has this information been OBJ.
tanned?
Answer. II has been observed by
those engaged il the work Of tick
eradication that, towards the end OF
the season, under the 21-day method,
there are always number of cattle,
CT herds, still remaining tick-infested.
I,'hile with 1f-day dipping there may
be none, or only very few, with ticks
on them.
Then the dipping periods are based
upon the time required for the ticks
to develop on the cattle and fall off?
Answer. Precisely so. The adop.
ton of the 14-day periods is TO- de-
stroy all of the ticks that have BE-
come attached to the cattle in the in
tervals between clippings, without any
Of them having dropped off.
How long, relatively, will it take to
clean parish, or section, of ticks un-
der the 14.day and 21-day dipping pc.
RODS?
Answer. With the full co-opera.
ton of everyone interested, the ticks
may be cleaned up in one season un-
der the 14-day periods; while under
the 21-dag periods it may take tvs
or three or more seasons, as has been
the case in number of parishes.
Do ticks have any effect on milk
production?
Answer. Federal experts have test.
ed this question. and they report that
cattle which have been freed Of ticks
have given an increased milk pro
duction Of from Is to ~ per cent, de-
pending on how grossly they had pre-
viously been infested. II we should
strike an average of 25 per cent, II
would mean that the dairyman who
continued to feed ticks on his COWS
was throwing away an equivalent Of
one bucketful Of milk out of every
four which his cows would produce
r7n5er tick-freednm
What effect do the ticks have, IL
any. on the development Of beet
catHe?
.nswer. They prevent develop
ant, because great deal of the
blood which the feed makes, and that
should be used to nourish the animal,
is appropriated By the ticks, and the
benefit of the feed is, therefore, lost
to the animal.
Are all the other states dipping
their cattle every "a days7
Answer. Yes. Some Of them
adopted the 14-day periods at the
beginning of the work. and others
that had commenced with the q days
have since abandoned the longer IN
tervals for the 14-day method as the
results have been found so much
more satisfactory
1t is believed, then, that 1t Is pos
sible to eradicate the cattle ticks
from a parish, or even the state, if all
the cattle are dipped in the standard
arsenicaI solution every IL days for
ore season?
Answer. Yes. II is being done in
other states, and parts of this state
at the present time. However, to be
able to accomplish it satisfactorily 1t
will require cooperation on the part
of everyone concerned and interested
in the work.
When once the state is tiek.fr.e
will there be any danger of re-infes
tation?
Answer. None. The federal gov
eminent and the state will see that
rigid quarantine is maintained against
the Introduction of any tick-infested
cattle. That is provided for now in
act No. IS Of the General Assembly
Of 1916, and by federal regulation.
What Is a condition Of tick-ireedon
expected to mean to the state?
