Some Of the questions most IRE
Q"entiy asked on tick e1adtcatio, are
- Veced below by DR.. w. H. Daym-
pc, OF the Department of Vetsriary
Science, Louisiana State Univerty:
Why is II necessary to dip cttle
J every a Gays during the seaso to
get rid of the ticker
Answer. During the warm seson
OF the year, the average time reAtr-
81 by the lick to develop, from he
small larv4'. or seed tick, afternt-
tachtng to cattle, until the largefs-
male tick natures and drops to he
ground to lay her egg, Is about ~
days. But while % days may be lie
average, many ticks mature earkr
than that time. Consequently 1t rs
been found that the 21-day dippis
periods do not catch the earli9r-ln-
turing ticks, which drop Off and KEEP
Oh making more ticks, thereby dels-
Ing the final results. On the othr
Rand, by dipping cattle every Il day
al CT the ticks that become actacad
10 them In the intervals are kiue,
because none Of them mature an
drop of before IA days.
How has this information been 81
ta'ned?

! those engaged III the work Of ticl
! eradication that. i,.vards the end OF
( the season, uHdcy ,i.e 2i-day method
! there are always nurher Of cattle,
! CT ha1d3, still TOT. aiming tick-infssted.
! While with IA day 6lrp!ng there may
be none, or Only very few. with ticks
on them.
I Then the dipping periods are based
upon the tinne required for tho ticks
to eo!eloa CT the cattle and fall off9

ton OF the 14-day periods is to do

come attached to the cattle In the in.

Of them having dropped off.
How long. relatively, will IL take 70
clean Pa''sh, or section, Of ticks vr-
der the 14-tar and 21-day dipping ne
riods7
Answer. With the full co-opsra.
ton OF everyone interested, the ticks

2roduccion7
Answeg. Federal experts have test
ed this question, end they report that
cattle "h Cd have hen freed OF tict,
have Given En- IN >ssed milk PRO-
ductioa Of from ~ to 3 per cent. de-
pending On how grossly they had ore
Vicusly been infested II we should
strike an average Of % per cent, It
would mean that the G.-iry,na1 who
continued to feed ticks on his COWS
was throwing away an esuivelent Of
one bucketful OF milk on. of eyerv
four which his cows would produce
under tici.-rres6om.
