Some Of the questions most fr'
Quently asked on tick eradication ar
answered below by DR.. w. H. Dalryn
pie, Of the Department Of Veterinar
Science, Louisiana State University
! Why is It necessary to dip cattl
every ID days during the season t
get rid Of the ticks?
/, Answer During the warm seasol
of the year, the average time requil
ed by the tick to develop, from tn
small larval, or seed tick, after at
taching to cattle, until the large fe
male tick natures and drops to tn
ground to lay her egg, is about 2
days. But while 90 days may be tn,
average, many ticks mature earlier
than that time. Consequently it ha
been found that the 21-day dipping
periods do not catch the earlier-ma
turing ticks, which drop off and keeI
on making more ticks, thereby delay
ing the final results. On the other
all of the ticks that become attached
to them in the intervals are killed
because none of them mature and
drop off before IA days.
How has this information been oh
tanned?
Answer. It has been observed by
those engaged III the work Of tick
eradication that. towards the end OF
40 ID
there are always number of cattle
or herds, still remaining tick-infested
While with 14-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 OF?
Answer. Precisely so. The adop.
ton of the 14-day periods is to do
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 of.
How long, relatively, will it take to
clean 4 parish, or section, Of ticks un-
der the 1+-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-day periods it may take two
or three or more seasons, as mas 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 AZ per cent, de-
pending on how grossly they had pre-
viously been infested. If we should
strike an average Of IS per cent, 1t
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
under tfck-freedom.
} what effect do the ticks have, it
any, on the development Of beer
eattle7
Answer. They prevent develop
ment, because a 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 ~ days?
Answer. Yes. Some Of them
adopted the 14-day periods at the
beginning of the work, and others
that had commenced with the 81 days
have since abandoned the longer in
tervals for the 14-day method. as the
results have been found so much
more satisfactory.
It is believed, then, that Il Is DOS
sibIe to eradicate the cattle ticks
from a parish, or even the state, IT all
the cattle are dipped in the standard
arsenical solution every "a days for
one season?
Answer. Yes. It is being done in
other states, and parts of this state
at the present time. However. to be
able to accomplish it satisfactorily it
will require cooperation on the part
Of everyone concerned and interested
in the work.
When once the state is tjck.fr.e
will there be any danger Of reinfes-
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. 18 Of the General Assembly
81 1915, and by federal regulation.
What Is a condition Of tIek-freedon,
expected to mean TO the state?
Answer. It will mean that Louis.
lana will be in a position to pro-
gross agriculturally, and, otherwise,
Is the more progressive states have
done that have never suffered from
