Care of the sow and piglet
A healthy well-fed sow will be able to rear at least 20 piglets each year.
If the sow has too many piglets to feed, or if a sow dies, the young can be fostered or hand reared. |
Learning objectives
After studying this unit you should:
1 Know if the sow is a good mother.
2 Judge if the piglets are feeding well.
3 Know how to foster piglets.
4 Know how to hand-rear piglets.
How good a mother is the sow?
A sow should have at least fourteen teats which should be long
and thin enough for the piglet to grasp. Each piglet suckles from its
own teat feeding every hour. The first born and stronger piglets use the
teats nearest the sow's head which produce most milk. As a sow gets
older and has more lifters the teats can become large making it
difficult for the piglet to suckle. Sometimes the back teats do not
produce much milk. A sow may be unable to feed all her young and is no
longer fit for breeding.
A sow can suffer from mastitis which may develop as a result of
damage to the teats caused by the piglets teeth. Clipping the teeth of
the piglet (see Unit 27) prevents cuts to the teats.
Are the young feeding well?
Not all of the piglets will grow at the same rate, some will be
born smaller than the others. They fight for feed and the smaller
piglets will grow at a slower rate and even die. You can expect to see a
difference in weight gain and growth between the members of any litter,
but if all of the piglets do not grow well and there are no obvious
signs of disease you should suspect poor milk production by the mother.
This is often the case with old sows.
It can become necessary to foster the piglets, i.e. put them with a different sow for feeding.
Fostering piglets
It is essential for all piglets to take colostrum from the mother. They will take the first feed within 1 hour of being born.
If a sow dies during farrowing her lifter can be fostered to
another. The orphans should be mixed in with the sow's own litter so
that she will accept them. However the foster mother will not be able to
feed both lifters at the same time and it will be necessary to use
several foster mothers to feed the orphans.
Hand rearing piglets
A sow may die and there is no foster mother available. The litter
can be reared by hand feeding. To hand rear a litter the following will
be needed:
· Feeding bottles and teats (nipples) which are thoroughly cleaned between each feeding.
· A clean dry box containing clean bedding for the newborn piglets which can be kept in a warm place.
· Regular feeds must be given at intervals of 1 to 2 hours.
· Cow's colostrum is the best substitute for the sow's colostrum and after 3 to 4 days the piglets can be given milk.
