Stockperson’s clinical signs
of an unwell pig
Know what is normal about
your pigs
– if you don’t know what is
normal how can you recognize abnormal?
|
Before entering
the pen |
||
|
Look |
Pig not
eating |
Pigs generally love food and a change in
their eating patterns should always be a cause of further investigation |
|
Change in behaviour |
Depending on the group size pigs
individual behaviours may be known or the group has its own behaviour
patterns |
|
|
Ideally the stockperson will know all the
pigs personally, however, even in a large group; individual pigs tend to
stand out, whereas the mass, sadly are unknown. The pigs that do standout are the extremes
– the top social order pigs, the lower social pigs and perhaps a few others
who have unusual body markings – wolf pig, leopard spotted etc. |
||
|
Group
behaviours |
||
|
Lying patterns |
Try to observe the known pigs and note
their lying patterns and position within the group. A sow standing at 2.00 in the afternoon, while
all her companions are asleep may be in heat.
She is exhibiting an unusual behaviour |
|
|
Individual being different |
Look for pigs who are separate from
the group |
|
|
Note groups of pigs gathered around a
drinker or a feeder |
||
|
Listen |
Note noises coughing or sneezing |
On entry to the room notice the sounds
of greeting made by the pigs. Pigs
with Swine Influenza are often very quiet and reluctant to get up as you
enter. Well managed pigs should be
pleased to see you. |
|
As the pigs move around, note any
coughing or sneezing |
||
|
Smell |
|
Become familiar with the normal body
odours of pigs. Swine Dysentery and
Swine Fever may cause malodorous smells. |
|
Enter the pen
and walk the pigs |
||
|
Look |
|
Look for the individuals, give them
memorable names. |
|
Movement |
Ensure all the pigs get up. |
|
|
Note pigs can be stiff or rising, but
within 5 to 10 strides the stiffness should walk off |
||
|
Walk over to any pigs who fail to rise
or walk off any stiffness |
||
|
Urination |
When pigs rise, particularly in the
morning they will urinate within 5 minutes.
Note the colour of the urine and the posture of the pig urinating. |
|
|
Blood |
Look for any blood on the floor or
walls. |
|
|
Floor |
Look at the floor for the consistency of
the stools. |
|
|
Listen |
|
As the pigs move around note any
coughing or sneezing |
|
Smell |
|
Smell the air – if a pig has died the
first indication may be a smell |
|
Individual pig
behaviour |
||
|
This includes any pig placed in a compromised/hospital
pen. |
||
|
Pigs housed in small numbers should all
be given names. This should include
artificial insemination centres and adults on farms of less than 50 sows. |
||
|
Know |
Behaviour |
Know the pig’s normal behaviour and note any
sudden or progressive change in behaviour |
|
Feed |
Know what food the pig likes and
dislikes. |
|
|
Reproduction |
Know what stage of reproduction the pig
is at and note if the expected oestrus behaviour patterns fails to
materialise |
|
|
Note changes in males (even when
castrated) can occur in the presence of receptive females |
||
|

Loss of appetite – pigs should beg for
food |

aggressive |
||
|
Changes in head/ear posture |

||
|
Locomotor changes – reluctance to get up,
do normal tricks |
||
|
Dirty anal/tail area – diarrhoea. Changes in the stools. Signs of vomit |
||
|
Listen |
|
Coughing, sneezing, wheezing and
breathing depth |
|
Feel |

Presence of a lump – may be felt rather
than seen |
Once you have identified that there may be a problem,
examine the pig in more detail.
