210 The Diseases of Animals 
dition of the udder, such as might result from a tumor 
or tuberculosis in this gland. In the treatment, condi- 
tions responsible for the disease should be looked for, 
and, if possible, removed. Bathing the udder with hot 
water and milking frequently give good results. 
Blue, bitter, “slippery” or putrid milk, is caused by 
the presence of germs which have gained entrance to 
the udder. The disease can be treated by milking the 
gland clean frequently and injecting a solution of boric 
acid, about ten grains to the ounce of water. The 
solution can be injected by using a milking tube—a 
rubber tube and funnel. This solution can be used 
twice daily, after milking. 
Bad odors in milk often come from strong or bad 
odors about the stable. The source of the taint should 
be removed and the milk well aerated. 
MAMMITIS 
Mammitis is inflammation of the mammary gland or 
udder. It is called “caked bag” and “garget.” The 
term garget is usually applied to those eases in which 
the milk secretion is altered and appears as a thick or 
stringy fluid. 
Inflammation of the mammary gland usually occurs 
soon after the young is born, when the gland is ac- 
tive and congested with blood. Inflammation may be 
set up by irritation of any kind,—injuries, such as 
kicks or blows, or another animal stepping on the 
udder, the retention of milk too long without being 
drawn, and especially by germs entering the udder.
