is tubercular, it is not advisable to practise segregation and quarantine.
This may be advisable if the reactor is a valuable breeding animal, unless
visible symptoms are shown. The milk from reacting cows may be used if it
is boiled or sterilized. Whenever a calf is born of a reactor, it should be
separated from the mother and fed milk from a healthy cow.

The separation of the tubercular from the healthy cows must be complete.
Separate buildings, yards and pastures that do not join the quarters where
the healthy animals are kept should be provided. The person attending the
reactors should not attend the healthy animals, and separate forks,
shovels, pails and other utensils should be provided for the two herds.

The best method of controlling tuberculosis in hogs is to slaughter all
reactors, disinfect yards and houses and move the herd. If the old quarters
are free from filth and carefully disinfected, the hogs may be returned
without danger of infection after six months. A retest of the herd should
be made before returning them to the permanent quarters and the reactors
slaughtered.
