Splay leg
This is a condition in which the newborn piglet is unable to keep its legs together.
Alternative names: abduction of the legs syndrome, splayed legs disease
Information
This is a condition in which the newborn piglet is unable to keep its hind limbs (and, occasionally, his front limbs) together; it affects up to 2% of piglets. Their mobility is limited which makes it difficult for them to access a nipple.
Symptoms
Sows
- Not seen.
Nursing piglets
- The piglets are not able to stand and the hind limbs are deflected laterally, therefore they often adopt a dog sitting position.
- They typically die from starvation, or crushing as the piglet can not get away from the sow.
- Not viable pigs.
Nursery and fattening stage
- Not seen.
Causes / Contributing Factors
- It is more common in the Landrace breed and in males.
- The disease is caused by the immaturity of muscle fibers of the hindquarters, around the pelvis and occasionally the forelimbs.
- This condition worsens when the pig is standing on very soft, wet, and slippery floors.
Diagnosis
- Based on clinical signs.
Control/Prevention
- As soon as the affected piglets are identified, put a dressing on hind legs joints with tape 25 mm wide, leaving a gap of 50-80 mm. The same procedure applies to the forelimbs. The tape must be passed around the leg, just above the dewclaw. Do not use string as it will constrict the legs.
- Hold the piglet by its hind legs and perform a vigorous massage on the muscles around the pelvis and on the front and back of the hind legs. Repeat this 3 or 4 times during the first day.
- Assist the piglet suckle regularly.
- Give the pig about 10 ml colostrum immediately after birth.
- Confine the strongest and mobile piglets in a warm area for an hour to allow splay leg piglets have access to the nipples.
