The gestation period of a pig is sixteen weeks.
When you buy in a
gilt you will be given an approximate due date. If you have had
her served by your own boar then it is essential to keep clear
records. It is all too easy to confuse pigs and their dates. To put
the wrong sow into a crate would be to court disaster with the
litter you have not protected. Put the sow into the crate a day or
so before she is due to farrow. Give her plenty of short cut straw
to lie on — long straw can tangle piglets. Many sows make a nest
for themselves with the straw. When the piglets start to arrive you
should take them away, wipe them clean and dry and pop them
under an infra-red light until the total delivery is finished. The sow
should not be allowed to eat the afterbirth or to lick the piglets if
they still have blood on. This could overexcite her and tales of pigs
eating their young are not old wives' tales. When all the piglets
have arrived let them go to their mother. Most pigs make excellent
mothers, they flop over on to their sides and give rhythmic grunts
to stimulate the piglets.
Newly born piglets are wonderful creatures. They are quite
ready to leap up and start exploring — they are inquisitive and full
of 'go'. That is one of the main reasons why they get into trouble
if allowed to do what they want to the instant they are born. Left
to their own devices, they have an uncanny instinct of making
straight for the sow's mouth — exactly where you do not want
them until the whole situation has calmed down.
A creep area that
the mother cannot get into, complete with an infra-red light, gives
them the greatest chance of survival. If there is only one warm
spot in the pen and the sow can get to it, they will all pile into it
and the little ones will get squashed. If you cannot obtain a
farrowing crate or are totally opposed to using one, the next best
thing is to fix a rail nine inches away from the wall and the same
distance up from the floor; this at least gives the piglets some
chance of escape. What it does not do is help anyone who has to
assist at the birth. A heavy sow is not only a threat because of her
size, she can bite with shattering power.
