Fourteen.Day Dipping.

Fourteen.Day Dipping.
Some of the questions most fire.
quently asked on tick eradication are
answered below by DR.. w. H. Dalrym-
pie, of the Department of 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 reQuir-
ed by the tick to develop, from the
small larval, or seed tick, after at
taching to cattle, until the large fe-
male tick natures and drops to the
ground to lay her egg, is about %
days. But while % days may be the
average, many ticks mature earlier
than that time. Consequently it has
been found that the 21-day dipping
periods do not catch the earlier-rna-
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 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 in the work of tick
eradication that, towards the end OF
the season, under the 21-day method.
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 Oft?
Answer. Precisely so. The adop.
!. ton Of the 14-day periods is to dc
stroy all of the ticks that have be-
come attached to the cattle in the in.
tervals between dippings. without any
Of them having dropped of.
How Tong, relatively, will it take "a
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 I'm
! der the 14-day periods; while under
the 21-day periods it may take two
or three or more seasons, as has been
the case in a number of parishes:
| Do ticks have any effect on mill
production?
/ Answer Federal experts have test
ed this question, and they report tina
cattle which have been freed Of tick
have given an increased milk pro
duction Of from Is to AZ per cent, de
i pending on how grossly they had pre-
viously been infested. II we shout,
strike an average Of Is per cent, j
would mean that the dairyman whit
continued to feed ticks on his cow
was throwing away an equivalent o
one bucketful of milk out of ever
four which his cows would produc
:. under tick-freedom.
What effect do the ticks have,
any, on the development Of bee
cattle7
Answer They prevent develop
ment. because a great deal of tn
blood which the feed makes, and tha
should be used to nonrish the ANNA
! is appropriated by the ticks, and tn
benefit of the feed is, therefore, los
! to the animal.
Are all the other states dippin
] their cattle every "A days?
Answer. Yes. Some Of thel
J adopted the 14-day periods at I'll
! beginning of the work, and othel
I that had commenced with the 81 day
J have since abandoned the longer i
tervals for the 14-day method. as IL

one season7
j. Answer. Yes. It is being done
4 other states, and parts of this sta

able to accomplish it satisfactorily

Of everyone concerned and interest,
in the work.
