then being exercised. Some animals keep up in good condition and look
perfectly healthy while some get emaciated, have constipation, variable
appetite, and sometimes growths or abscesses can be felt or seen in the
udder or glands of the body and neck.

However, cattle showing any weakness, or the above symptoms, should be
tested for tuberculosis by a competent veterinarian who has had the
privileges of a veterinary education and experience in the
administration of tuberculin.

TREATMENT: It is not advisable to treat tuberculosis. Thus far, medicine
has failed to relieve the affected animal, or kill the bacillus of
tuberculosis in a living animal. The infected animals should be disposed
of on account of tubercular cows giving birth to tubercular calves, the
milk being unfit for human consumption, unless it is thoroughly
pasteurized. Infected cattle should be separated from healthy ones, as
the disease spreads very rapidly. Drinking and feeding troughs are a
means of spreading the infection, therefore, suspected cases of
tuberculosis should be tested and if the animals react, they should be
slaughtered, and if the disease is localized, passed for human
consumption. The meat of animals suspected of having tuberculosis, or
reacting from tuberculin test, should be well cooked.

TWISTED STOMACH WORM

CAUSE: Cattle become affected with this worm by grazing in pastures in
which infested cattle have grazed and scattered their droppings. The
worms in the stomach produce a multitude of eggs of microscopic size,
which pass out of the body with the feces. In warm weather, these eggs
hatch in a few hours; if the temperature remains about freezing point,
they soon die. The eggs are also destroyed, by dryness, but, on the
other hand, moisture, if the weather is warm, favors their development.
The twisted worm measures one-half inch to one and one-half inches in
length.

SYMPTOMS: General weakness, loss of flesh, anemia, dullness, capricious
appetite, excessive thirst, paleness of the skin and mucous membranes of
the mouth and eyes, and dropsical swelling, especially that of the lower
jaw. Diarrhoea always accompanies this condition and if the feces is
carefully examined the small worms may be seen wriggling about like
little snakes, or when an animal dies; and the fourth stomach is opened,
these worms can be seen in large quantities.

TREATMENT: Preventive measures are important, as damp, marshy soil
favors the development
