COMMON DISEASES OF SWINE 343 
shown by a weaving of the body, knuckling of the fetlocks, 
and finally a paralysis more or less complete. The animal is 
unable to raise itself on its hind legs and often drags the hind 
quarters as it moves about. The disease occurs in swine of 
all ages. This disease is popularly supposed to be caused by 
‘kidney worm,’ but there is no evidence to support this belief. 
The disease seems to be located in the spinal cord at the lumbar 
region, but the actual cause is unknown at present. 
‘Some cases recover without treatment, but a majority of 
the cases prove fatal. Generally the treatment is to give a 
purgative of from one-half to two ounces of castor oil, depend- 
ing upon the size of the animal, followed by nourishing, easily 
digested feed. Rubbing the back vigorously with a good 
veterinary liniment once daily is also beneficial.” 
MANGE, 
Mange is caused by very small animal parasites called 
mange mites, which burrow in the outer layer of the skin. 
The disease is most troublesome in young pigs, causing 
great irritation, indicated by the little pigs scratching and rub- 
bing themselves. Later, the hair stands erect, and thick scabs 
form at the roots of the hair on the neck and shoulder top and 
about the ears and face. Often the scabs extend along the 
back to the root of the tail. 
Dr. Mayo, of the Virginia Experiment Station, strongly 
recommends the lime and sulphur dip, which is made as fol- 
lows: Take 8 pounds of fresh lime and slake with enough 
water to form a thick paste. Sift into this paste 24 pounds 
of flowers of sulphur and mix thoroughly with a hoe. Place 
in a kettle with 25 or 30 gallons of water and boil for at least 
one hour, then add enough water to make 100 gallons of dip. 
The dip should be used warm, about 100 or 110 degrees 
Fahrenheit.
