answered below by Dr. ". Fl. Dalrym-
PIE, of the Department OF Veterinary
Science. Louisinua State University:
Why Is II necessary to dip cattle
every "a days during the season to
get rid Of the ticks2
Answer. During the warm season
Of the year, the ayeraye time reqUr-
ed BIZ the tick to develop, from the
small larval, Or sead tick. after at
taching to cattis. until the large fe-
male tick natures and drops to The
ground 10 lay her egs. Is about %
days But while y dIve may be the
average, many ticks mature earlier
than that time. Consequently It has
been found that the - dsy dipping
periods DO not c.tch the earliar.ma-
turing ticks, whicl drop off and keep
Oh making uor1 cks, thereby deIey-
ing the fnal results. On the other
hand, by dipping cattle every II days,
all OF the ticks t. at become attached
70 them in the intervals are killed,
! because none OF them mature and
drop OK Dcitlc 1T h&yS
; How has this information been CD,
! taine9?
Answer. It has been observed b.
! shore engaged In the work OF ticI
eradication ths.. towards the end OF
| the season, und.; the 21-day method,
| there are always a rumher Of cattle,
or herds, still remaining ticis-r Tested.
While with 14-day dipping ttare may
be none. or only very few, witt ticks
On them.
Then the dipping periods are based
uoen the time required for tbs ticks
to develop o. the cattle and fall on?
1 Answer. Precisely so. The adop-
ton OF the 14day periods IS to de-
5troy ell o. he ticks that have be-
come attached to the cattle In the in
tsryals between dipDings. without any
of them having dropped of.
How long. relatively, will II take 70
clean q parish, or eact'on, CT ticks un-
der the f4day and 21-day dipping pc
rIcds?
Answer WITH the full co-opera.
ton OF eyer-ole Interested, the ticks
may be cleaned uo in one season un-
der thu 14-6av rer!3ds; while under
The 21.day periods il may take two
or three or Ao:e SEASONS. IS mas been
he case ia a number Of parishes.
% ticks have any eject on milk
production?
EaI1 i f,art r
o. his question, and they report that
cattle which have beer free Of ticks
have given an increased milk pro-
ductfoa OF from - to a. per cent, de-
pending on how grossly they had pre-
vicusiy been infested. II we should
strike an average OF Is per cent. IL
would mean that the dalryKnaA who
continued to feed ticks On HE cows
was throwing awsy an equivalent OF
one huclctiul Of milk out Of every
four which his COWS would produce
under t!cE-Pres6om.
What effect do the ticks have, II
any, on the deveicame Of bee,
cattIc?
Answer. They prevent develop
ment. bacause q s. =, deal of the
b.ood which the feed mahas, and the,
should be used to = ~, the antmc'
! is appropriated by tn 8, and he
benefit of the ed is, therefore lost
/ to the animal.
:. Are all TIL. other states dip,in;
! their cattle g. ,ry a dsvs?
! Answer. Yes. Some Of thea
adopted the i4-dey periods AZ the
. | beginning of the wort, ecf others
t,at had conmencao with the q dave
