We have very few calls from the vet and these are almost entirely
limited to when a sow or gilt is farrowing (giving birth).
A
farrowing house is essential if you have more than a very few sows. With
one or two you could use a stable or similar building. The main
aim is to have the area as germ-free as possible and to provide
adequate protection for the piglets. The protection is mainly from
their mother. A large sow is an unwieldy creature and as she is
producing up to eleven tiny piglets the odds of her squashing one
or two are quite high. To prevent this, many births take place in a
farrowing crate. These are metal crates that restrain the pig from
turning round and keep her confined during the birth. We use
them as there does not really seem to be any other satisfactory
way. They are also extremely useful if the vet has to render
assistance. A boar pen is the last necessary building. A boar should
be housed on its own but fairly close to the females you want him
to serve. This encourages the females to come on heat.
We only run a few pigs extensively as our land is heavy clay and
therefore cold and wet. Pigs thrive best on exactly the opposite
soil, one that is well drained and warm. Pigs kept in fields in arcs -
those tin-covered huts, rather like miniature Nissen huts — require
plenty of warm straw for bedding and supplementary food. They
will take some food from the grass but this is not sufficient. Some
pigs breed out in their huts, the major drawback here being that if
there are difficulties it is extremely hard to deal with an
unrestrained pig and, of course, since many births occur at night, you
have the dark as well as the wind and rain with which to contend.
Having said all that, it is a fact that piglets who live out with their
mothers tend to thrive. Because they have free access to the
ground and its inherent minerals, they do not need the injections
of iron that indoor-reared piglets must have. Probably the best
compromise if your land is suitable for running pigs is to breed
them in confinement and gradually introduce them to the open
air.
