Do you wean less than 12 per
sow: |
- Breeding routines
- The major cause of piglets not being
weaned is an empty farrowing place. Each empty place equates
to 12 lost piglets. Pre-weaning mortality starts in the
service area, ensuring the numbers served is sufficient for
the current farrowing rate and to enhance litter size.
- All-in all-out and basic hygiene
- To reduce pre-weaning mortality hygiene
has got to be good. On a lot of farms all-in all-out is
believed to be practiced, but with fostering and foster sows
this is rarely achieved. The all-in all-out must also be
complete, i.e. do not forget the water supplies.
- Nutrition of the gestating sow
- Poor control over gestation nutrition
results in low birth weights, udder oedema, mastitis
problems and there is a negative relationship between the
quantify fed in gestation and the appetite in the farrowing
house.
- Nutrition of the lactating sow
- Few producers are able to maximize the
sow's potential for milk production, resulting in under
nourished piglets. Copious supplies of water are critical.
Feeding of the lactating sow is a critical area in the
farrowing house.
- Adequate farrowing routines
- These are necessary to reduce the number
of stillborn piglets and to provide care in the first
critical 24 hours.
- Farrowing accommodation design
- Chilling is the number one reason for
piglet loss. Farrowing houses must not have any draughts.
There are two micro-environments necessary, the sow at
16-18�C and the piglet at 30�C. The farrowing crate has got
to be able to accommodate the modern sow.
- Adequate antibody protection via colostrum
- The piglet is born with no protection.
Providing sufficient protection starts with an effective
vaccination program and protocols to maximize the
colostrum intake. Draughts again are a killer.
- Efficient cross-fostering routines
- Protocols should be in place to provide
efficient cross-fostering shortly after birth and later
during lactation. There also needs to be provision for the
weak piglet at weaning.
- Maximize piglets' energy intake
- Through good access to teats, providing
good mothering sows and ensuring sows provide adequate milk.
Liquid feed before day 14 may enhance gut development and
palatable creep feed is needed from day 14 to improve
weaning weights.
- Efficient and humane piglet processing
controls
- Clean well maintained and effective
protocols for teeth clipping, tail docking and iron
injecting should be in place. Poor teeth clipping is a major
cause of joint ill.
