Re: "Sheep Dip" in Chama

Quote
USDA Yearbook of Agriculture 1956
TREATMENT of sheep and goats infested
with psoroptic and chorioptic
scabies is with dips approved by the
Department of Agriculture. The approved
dips contain lime-sulfur, nicotine
sulfate, wettable BHC, or wettable
lindane.
…
The dipping vat should be filled
with enough clean, unheated water
to cover the animals—ordinarily 40
to 48 inches deep. After the water is
measured and put into the vat, the
required amount of BHC powder is
added and thoroughly stirred. The
dip should be stirred again after any
interruption in dipping.

Each animal must be held in the dip
not less than r minute to assure saturation
of the skin and fleece. The head
of each animal should be submerged
at least twice for an instant so that
the wool and hair about the head and
face are thoroughly wet.

Small lambs should be dipped in a
barrel. After they are a month old,
it is safe to let them swim through the
vat, but they should not be put into
the vat with adult sheep.

The dip should be changed as soon
as it becomes filthy, regardless of the
number of sheep that have been
dipped in it.
