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

Look

 

Loss of appetite – pigs should beg for food

Changes in behaviour – aggressive/less aggressive

Changes in head/ear posture

Changes in eye’s brightness

Change in skin colour or hair position

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.
