Handling
and Moving Pigs
Most pigs are not used to being handled. They become very vocal when caught and will not settle easily. Pigs will work as a herd or as individuals, before moving a group of pigs think of escape routes you would take and then try to block them.

|
Young pigs may be picked up and will generally settle |

Older
pigs examine within a crate or
restrain using a loop around the upper jaw

Design
passageway to prevent escapes. |
Young
pigs may be easier to move in a barrow |
|
Pigs
have a wide angle 310 degree vision which allows them to see behind themselves
without turning their heads. They
are easily distracted by objects to the front and sides and sharp changes in
floor texture and appearance. A shaft
of sunlight is sufficient to affect pig movement. |

When
moving growers pigs use a pig boards, hands and your voice. Do not use electric prods |
There
is never any need to use violence - the pig will object |
Pigs
move much easier in a quiet controlled environment |

Pigs
can be trained to a harness. This is
how they are used to hunt truffles. |
Boars
can be trained to walk to heel and follow a route |
Take special
care with boars or lactating sows.

Loading
finishing pig can be a particularly stressful time for a pig. It is essential to carefully design the
loading area. Avoid steps and any rise
over 20o. Ensure the area
is well lit with out corners. The use
of hydraulic lifts (right) is to be encouraged. With ramps they should be constructed with at
least 850 mm high to prevent distraction.
The passageway should allow 2 pigs to move at the same time, allowing
physical contact. Have an offset panel
at ramp entrances, rather than a funnel.
A catwalk along the outside of the ramp will allow staff easy access
to the pigs on the ramp to improve pig movement. |

mixing pigs
|
Care is
needed because: |
|
|
1 |
Pigs will fight whilst they establish their ‘pecking order’. This happens whenever the group is
disturbed. |
|
2 |
It takes 1-2 days to establish the pecking order, and performance
may be compromised during this period. |
|
3 |
Pigs need time and space to work out their pecking order. After this, the weaker pig will back down. |
For all pigs;
|
|
|
1 |
Pigs should be kept as much as possible in stable social groups,
and mixing at any stage between accommodation types should be kept to a
minimum. |
|
2 |
Avoid mixing in pens where sharp edges to feed troughs and
drinkers protrude, and can injure the pigs. |
|
3 |
Always mix pigs of similar size. |
|
4 |
As a general rule, never introduce less than 3 pigs into an
established larger group. However, it
may be necessary to introduce 1 or 2 sows to dynamic service groups. |
|
5 |
Low levels of lighting can reduce aggression when mixing. This must not be used for longer than 1-2
days. |
|
6 |
Resorting to the use of tranquilisers and masking sprays may
indicate that the mixing methods and facilities on your farm are inadequate. |
For sows:
|
|
|
1 |
Allow plenty of space (eg if mixing sows, you need 3.5 m2
per sow) so that there is enough space to get away if chased or
threatened. Sows will mostly chase for
less than 2.5 m. |
|
2 |
Ideally only mix sows at weaning.
Avoid mixing sows 5-21 days after service as this is when the eggs
implant and stress can result in high numbers of returns. |
|
3 |
Use physical barriers in the pen such as big bales or plastic
sheeting suspended from the roof. This
allows a beaten pig to get out of sight and quickly ends the fight. |
|
4 |
Time mixing to fit in with management routines to best allow
supervision, however mixing in the evening may be best if you can arrange to
be there to oversee this. |
|
5 |
Use fresh straw at mixing – it acts as a cushion if fighting
occurs and increases surface grip. |
|
6 |
Consider ad lib feeding
when mixing. |
|
7 |
Consider allowing physical contact eg through a gate, between a
dynamic main group and a sub-group to be mixed into it, prior to mixing. This may reduce fighting when they are
introduced. |
|
8 |
Avoid re-mixing groups. If
practical mix sows back into their original groups post weaning. |
|
9 |
Avoid mixing in any form of cubicle system. Sows can be trapped easily and injured –
consider a specialist mixing pen. |
|
10 |
Consider breaking up the edge of the lying area with divisions so
that sub-groups can have their own areas. |
|
11 |
Try closing off a section of a large yard system for a few days
then penning the sub-group in this area when mixing. This helps to establish a new territory for
the smaller group. |
