sow should not have two litters a year. In any
case, the sows should be carried on comparatively light feed until time
to breed again, gaining a little in weight; and their treatment after
breeding should be as already detailed for pregnant sows.

When the boar arrives at the farm he should be dipped in a solution of
Pratts Dip and Disinfectant, as a matter of ordinary precaution against
the introduction of vermin. As an additional precaution, a quarantine
pen should be ready for him, especially if epizootics are prevalent. His
feed before change of owners should be known, and either adhered to or
changed gradually to suit the new conditions. If he has come from a long
distance it will be well to feed lightly until he is well acclimated.

Breeders generally advocate the practice of keeping a boar to himself
during the entire year--out of sight and hearing of the sows. However, a
boar is often allowed to run with the sows after they are safe in pig;
but during the breeding season it is by far the best policy to keep him
by himself, admitting a sow to his yard for mating, and allowing but one
service. The litters will generally be larger and the pigs stronger.

The boar should not serve more than two sows daily, preferably one in
the morning and one in the afternoon, and can serve 50 to 60 in a season
without difficulty.

In order to keep the boar in vigorous physical condition, he should be
given Pratts Hog Tonic regularly. The beneficial results will be seen in
the way of larger litters and stronger pigs.

The greatest drawback to the hog industry which breeders in this country
have to contend against is found in the losses which may be experienced
through the infestation of the animals, especially young pigs, by
parasites, through outbreaks of hog cholera or swine plague, or through
the contraction of tuberculosis.

In dealing with the diseases of hogs, preventive measures must be most
relied upon. The animals must be given dry and well-ventilated quarters,
which must be kept clean. Contrary to common belief, hogs have some
habits which raise them above other domestic animals from the
standpoint of cleanliness. For example, unless compelled to do so, a
hog will not sleep in its own filth. If part of the floor of the pen is
raised and kept well bedded with straw, while the rest is not, all
excrement will be left on the unbedded portion of the
