scab. It is in this way that innumerable mange mites cause the piling up
of scabs thus producing a very scaly condition. As Mange advances, the
scaly patches eventually pile up until they attain the thickness of
one-half inch, unless these scabs have been severely rubbed.

SYMPTOMS: Very easily detected, as a bunch of sheep that have been
recently infected will be uneasy or restless, rubbing, against fences,
posts, brush, etc., causing bunches of wool to loosen. The itching seems
to be more intense at night and during warm weather. The affected
animals will even make attempts to bite themselves, due to the agony
produced by the mange mite. If the skin is examined by the aid of a
magnifying glass, the mange mite can be easily noticed, or by scraping
the skin with a knife and placing the scabs on a dark paper and exposed
to the warmth of the sun, the mange mite moving about can readily be
seen with the naked eye. Mangy sheep become very poor and eventually
die.

PREVENTION: This is important, for although the disease is treated with
very good results, the mange mite annoy the sheep until they become very
weak and emaciated and the loss of wool is enormous due to the affected
animal continually rubbing against fences, brush, etc.

TREATMENT: Consists of using various dips, as Lime and Sulphur, which is
recommended by the United States Bureau of Animal Industry. This is very
effective and inexpensive. Scabby sheep should be dipped a week or ten
days after shearing; two dippings are necessary at the interval of ten
days. After dipping, move to non-infected range or pastures.

TICK

(Louse Fly)

CAUSE: The tick that infects sheep has a very small head sunken into its
round body. The head possesses a flexible trunk or snout that penetrates
the skin. Through this trunk, the ticks derive their nourishment by
sucking the blood from the body of the sheep. The tick is also provided
with three pairs of legs. The female lays her young in the form of a
spun egg (cocoon) which is oblong in shape and brown in color. This egg
is cemented to the wool of sheep where young ticks are hatched in about
four to six weeks.

SYMPTOMS: Long wooled sheep are more susceptible to this tick as their
wool provides shelter for both the tick and its eggs. After shearing the
sheep the ticks have a tendency to leave the body and to migrate to the
legs or to unshorn lambs where their snouts or trunks pierce the skin
which appears to becom
