atisfactory, although
in chronic cases and those occurring late in the fall beneficial results
have followed. If the animal is constipated, a drench containing 1 pound of
Epsom salt dissolved in 1 quart of water should be administered, followed
by sulphate of quinin in doses of 30 to 90 grains, according to the size of
the animal, four times a day until the system is well saturated with it.
Tincture of digitalis one-half ounce and alcohol 2 ounces may be combined
with the quinin, according to indications of individual cases. An iron
tonic containing reduced iron 2 ounces, powdered gentian 4 ounces, powdered
nux vomica 2 ounces, powdered rhubarb 2 ounces, and potassium nitrate 6
ounces will be found beneficial in the convalescent stage when the fever
has run its course. This tonic should be given in heaping teaspoonful doses
three times a day in the feed. Good nursing is essential in treating these
cases, and the animal should be given a nutritious, laxative diet with
plenty of clean and cool drinking water and allowed to rest in a quiet
place. If the stable or pasture is infested with ticks, the animal should
be placed in a tick-free inclosure to prevent additional infestation with
these parasites and the introduction of fresh infection into the blood.
Furthermore, all ticks that can be seen should be removed from the sick
cattle, as they keep weakening the animal by withdrawing a considerable
quantity of blood, and thereby retard recovery.
QUARANTINE REGULATIONS.
The sanitary regulations issued by the Department of Agriculture for the
control of cattle shipments from the infected districts have for their
initial purpose the prevention of the transportation of ticks from infected
regions to those that are not infected, either upon cattle or in stock cars
or other conveyer. They are based upon the fact that Texas fever is carried
north only by the cattle tick, and the exclusion of this parasite from the
noninfected territory has in every instance been found a certain method of
excluding Texas fever. The regulations governing the movement of cattle
from below the quarantine line are made yearly by the Secretary of
Agriculture, and they define the boundary of infected districts. The
infected area as now determined is shown in maps issued periodically.
In consequence of the enforcement of these quarantine regulations, Texas
fever has been practically prevented in the noninfected districts for
several years, and little
