uuently asked on tick eradication are
answered below by DR.. " II. Dalryn-
=. of the Department Of Veterinary
Science, Louisiana State University;
Why Is il necessary to dip cattle
every "a days during the season to
Get rid of the ticks?
Answer. During the warm season
of the year. tho average time Teiu'r-'
cd by the tick to develop, from IN"
mall larval, or seed tick, AFTER az
tachtng to cattle, until the large Ie-
male tick natures and drops 10 the
ground to lay her egg, Is about -
DAYS. But while % days may be the
average. mary ticks mature earlier
than Tint tie. Consequently II h2-
been found that the 2l-day dipping
periods do not catch the earlier-rn%-
turing ticks, which drop off and Keep
on making more ticks, thereby dCIay-
ing the final results. On the other
hand. by dipping cattle every IA DAYS,
all of the ticks that become Attached
ia them in the intervals are killed,
because none of them mature and
drop of before IA days
How has this information been OBJ
tained2
Answer. II has been observed by
those engaged III the work or tcH
eradication that, towards the end OF
the season under the 21-day method,
there are always a number OF cattle,
;,,;n i1E In q 81
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 sdop-
ton of the 14-day periods Is to de-
etroy 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 a parish, or section, Of ticks in
der tbs 14-aay and 2i-day dipping pc
RODS?
Answer With the fun co-opera
ton OF everyone interested, the ticks
may be cleaned np ia one season nm
der the 14day periods; while under
the 2l.day periods it may take two
or three or more seassns, as has been
the case In a number of parishes.
Do ticks have any effect on milk
psoduetien7
Answer. Federal experts have test
| ed this question. and they report thai
cattle which have been freed OF ticks
have given an Increased milk pro
fiuetion of from IS to AZ per cent, dc
pending On how grossly they had pre-
viousiy been infested. II We should
strike an average Of rs per cent, Il
would mean that the dairyman who
continued to feed ttehs on his cows
was throwing away an equivalent O
!: one buclsetfui Of milk out OF every
four whioA his COWS would preduc'
under Hek-ePeedom
! What effect do tire tlcks have,
any, on the development Of bee
eattie9
Answer They prevent develop
| ment, because q great deal OF tn
blood which the feed makes, and tina
should be used to noHFish the animal
Is appropriated by the ticks, and tn
| benefit Of the feed Is, therefore, los
10 the animal.
