5. Do not _over-feed_; give only as much as will be consumed at the
meal.
6. _Vary_ the food. Variety will create, or, at all events, increase
appetite, and it is most conducive to health. Let the variations be
governed by the condition of the _dung_ cast, which should be of a
medium consistence, and of a grayish-brown color; if _hard_, increase
the quantity of bran and succulent roots; if too _liquid_, diminish, or
dispense with bran, and make the mess firmer; add a portion of corn.
7. Feed the stock _separately_, in classes, according to their relative
conditions. Keep sows with young by themselves; store-hogs by
themselves; and bacon-hogs and porkers by themselves. It is not
advisable to keep the store-hogs too high in flesh, since high feeding
is calculated to retard development of form and bulk. It is better to
feed pigs intended to be put up for bacon _loosely_ and not too
abundantly, until they have attained their full stature; they can then
be brought into the highest possible condition in a surprisingly short
space of time.
8. Keep the swine _clean_, dry, and warm. Cleanliness, dryness, and
warmth are _essential_, and as imperative as feeding; for an inferior
description of food will, by their aid, succeed far better than the
highest feeding will without them.
