unusual amount of mineral matter. Pigs naturally root in the
ground and get minerals which the farmer needs to supply under
domestication. Several materials may be mixed together and used
for this purpose: Wood ashes, coal ashes, coal dust, charcoal, salt,
saltpetre, sulfur, copperas, lime dust, and rock phosphate dust.
A few or all of these materials may be mixed together and placed
in a suitable feeding hopper or in a pit where swine have constant
access to it. Do not mix these minerals with grain or
other feed for swine. Farmers often gather corn-cobs
in pits and char them for this purpose.
Mineral elements are needed in the body for
growth of bones, for the formation of blood, for the
supply of minerals in lean meat and to aid in the
proper secretion of digestive fluids. Sows with young
pigs are less likely to form pig-eating habits.
Feeding at Farrowing Time.—Special feeds for
sows should be supplied as farrowing time approaches,
Varm bran mashes are good if the winter is cold.
Thin mashes made from mill feeds mixed
with skimmilk should constitute the chief
ration before and after farrowing. For very
heavy or fleshy sows supply laxative feeds.

Saving of young pigs from death will soon pay for good
quarters. The house need not be expensive. The floor, if made
of concrete, should be well insulated with an under layer of tar
or tar paper so that the top will be warmed by the sow’s body.
Sometimes temporary platforms are laid over cold concrete floors.
Bedding must not be too abundant for fear of pigs being mashed
by their mothers. It should be changed often to keep it dry.
Around the sides of farrow pens provide a shelf or rail for pigs
to slip under and avoid being mashed by their mothers. (Fig.
226.) Each sow and litter should have a space in the house about
eight by eight feet. When permanent houses are built place them
where drainage is good, where summer sun may enter and where
shade can be provided in summer. A good wind break as a fence
or line of evergreen trees on the west and north sides should be
provided if possible.
