Dipping Vats for Hogs

By A. P. SPENCER,
District Agent, Co-Operative Demonstration Work.


Important Facts

1. Lice and fleas make hogs unthrifty because they suck the blood and lower
the vitality.
2. Lice and fleas remain on hogs constantly and cause severe irritation and
sores.
3. Hogs will make slow growth even with good feeding if they are infested with
parasites.
4. Lice and fleas lay their eggs in dust and litter; consequently the sleeping
quarters should be cleaned and disinfected regularly.
5. Eggs of these parasites hatch in about ten days in warm weather, but may
require three months or longer to hatch when the weather is dry and cold.
6. Dipping kills the parasites but does not destroy the eggs. It is necessary to
dip the hogs regularly to rid them of parasites.
7. Frequent dipping keeps the animals free from mange and allows sores to heal.
8. Hogs contract intestinal and lung worms from infected pastures and water.
Frequent change of pastures does much to keep tflem in check.
9. The hog vat can be used for dipping calves, goats, and sheep, to rid them of
parasites.

THE CHUTE between the Pen and Vat should be 10 feet long
and 15 inches wide.
THE DRIPPING PEN will catch the drippings, and may be
six feet by six feet, and will require a concrete floor, .13

(Compiled from Bulletin 185 of the Alabama Experiment Station)


DIPPING SOLUTIONS
FOR HOG LICE and FLEAS,
KEROSENE EMULSION
Dissolve one pound common soap in one gallon warm water.
Add one gallon kerosene oil, mixing thoroughly. Then add three
gallons hot water. Pour into Vat,
To fill the Vat will require about 36 pounds of soap and 36
gallons of kerosene,
CRUDE OIL and CRUDE OIL EMULSION are equally
effective,
Coal Tar Dips and Disinfectants give good results when used
at the full strength recommended, and are also good for sores and
mange,
The eggs (nits) are not destroyed by dips or oils, They
hatch in 10 to 14 days, The young lice must be killed as soon as
hatched or they soon reinfest the hogs.
Hogs should be dipped three or four times, ten days apart, to
rid them of lice, and then once a month afterward to keep them
clean.
