PREVENTION OF CONTAGIOUS DISEASES

Newly purchased animals or poultry should be segregated for from ten
days to two weeks to give opportunity for any infectious diseases with
which they may be afflicted, or have been exposed to, to fully develop.
This precaution will often save the buyer from loss.

Avoid exhibiting in fairs, shows, etc., where the health of your animals
might be jeopardized, especially through the presence of contagiously
affected animals. If you cannot be sure proper precautions are to be
taken, better forego your pride and possible prize ribbons.

HEREDITARY TENDENCIES

When breeding, it is of utmost importance to select a good female as
well as male, for the least faulty conformation in either will in all
probability be transferred to the offspring, viz.: an animal with a
crooked hind leg is subject to bone spavin, curbs, bog spavin,
thoroughpin, ring bone, etc., and is liable to transmit any of these
diseases, especially if exposed to slight exertion. A tubercular cow
will invariably give birth to a tubercular calf, or at any rate the calf
will contract tuberculosis from the milk.

EVOLUTION OF STOCK

During the transformation which our country has undergone, and is
undergoing, no one industry has experienced such marked changes as the
production and raising of livestock.

At the earliest time of which we have any record, and even up to within
comparatively recent years, large herds of horses and cattle ranged over
our plains in a wild state. At first no attempts were made to capture or
round up these herds, and later but one or two attempts per year, when
the young were branded and grown animals shipped, if possible, or driven
to available markets.

As the country became more thickly settled and populated these larger
herds were broken up, the ranges becoming divided and fenced. With this
segregation, attention to breeding and care of animals began to be
practiced, gradually causing the animal's evolution from the wild to the
domesticated state.

As this process of evolution progressed the animal became farther and
farther removed from its natural condition of living, becoming more
dependent on man for food and shelter, and with this change the animal's
former vitality and power to resist disease decreased markedly.

With the advancement of agriculture, and their resultant pro
