Lameness in Pet Pigs

 

Conformation concerns

Leg length – good length of leg

Leg length – too short

Leg angle

Good leg angle – good foot wear

Dropped pasterns, supernumerary digits are in contact with floor

Inversion of the foot – varus weight moved to the lateral foot

Toes point outwards – valgus – lateral deviation – weight moved to the medial foot

Problems seen particularly with angular deformities

Screw toes

Rolled hoof wall

Other toe and lower leg deformities

Splaying of toes

Genetic abnormalities – mule foot

Uneven toes, enlarge lateral toe

Toes overgrowth

Hoof craw, from coronary band.

Corn – swollen heel

Overgrowth of supernumerary digit

Interdigital growth

Interdigital abscess

 


 

General locomotor problems

Arthritic pig – middle aged

X ray of an arthritic limb

OCD in a growing pig

OCD lesions – these can be very common

Infected leg following trauma as shown at postmortem – another pig stood on the leg

Paralysis of the hind legs occurs due to a number of reasons – example shown was a invasive lymphoma growing adjacent to the spinal column - arrow

 


 

Control: Providing good a hoof environment

Muddy paddocks make for soft feet

Poor welfare conditions, often related to poor foot care

Straw can be very clean but is none wearing

An area of screenings will allow the pig’s feet to wear more normally

Treatment

Trimming while conscious

Trimming under anaesthesia
