Pig Bush Foot (Foot Rot): Tackling Lameness and Promoting Well-being in Swine

Pigs are susceptible to various ailments, one of which is bush foot. Understanding foot rot conditions, its causes, and effective treatment options is crucial for ensuring the overall health of your pigs.

What is Bush Foot?

Bush foot, also known as foot rot, is a condition that primarily affects pigs’ hooves, causing lameness. It is characterized by inflammation and infection, leading to pain and lameness. The onset of bush foot can be attributed to various bacteria.

Bush rot derives its name from the bushy appearance of the affected hoof, which results from the swelling and discharge associated with the infection.

Recognizing the symptoms of bush foot is crucial for early intervention. Affected pigs may limp, show lameness, swelling, increased heat around the hoof, discharge or pus, and a foul odor. Prompt diagnosis and appropriate treatment are vital to alleviate the pain and prevent the condition from worsening.

While the way pigs walk with Bush foot is similar to pig arthritis, bush foot shows up in the altered and injured hoof.

Causes of Pig Bush Foot or Foot Rot

Bush foot in pigs is primarily caused by bacterial infections, most notably Fusobacterium necrophorum and Dichelobacter nodosus. These bacteria thrive in moist and unsanitary environments, making pigs housed in unclean or damp conditions more susceptible to the condition.

When pigs come into contact with contaminated bedding, mud, or manure, the bacteria can penetrate the protective layers of the hoof, leading to infection and subsequent damage.

These bacteria breaks down the hoof tissues, creating an environment favorable for further bacterial growth and the onset of inflammation. Dichelobacter nodosus causes foot rot in sheep and can spread to pigs. It produces enzymes that break down the hoof horn, leading to tissue damage and lameness.

Damp and Unsanitary Environments Cause Foot Rot

Pigs housed in areas with poor hygiene, excessive moisture, or inadequate drainage are at a higher risk of developing bush foot. Wet and muddy conditions soften the hoof tissues, making them more susceptible to bacterial invasion.

Additionally, overcrowded or poorly ventilated housing facilities can create an environment conducive to the growth and spread of bacteria, further increasing the likelihood of infection.

When you can recognize the underlying causes of bush foot in pigs, you can implement preventive measures and create an environment that minimizes the risk of infection. Maintaining proper hygiene, providing suitable flooring, and ensuring adequate ventilation will significantly reduce the occurrence of this foot rot.

Symptoms and Signs of Pig Bush Foot

Signs of Bush Foot include a reluctance to stand, lameness in their hind legs, or walking on their tip-toes (known as paddling or goose-stepping) or knees. A warm, swollen claw clearly indicates that the pig has contracted septic laminitis.

If the infection has spread, an abscess will form. The pressure above the hoof will cause the skin to die (necrosis will set in), and the abscess will burst. The resulting pressure from the abscess can cause the pig to go lame and walk on its knees.

You Pig WIll Exhibit Lameness and Difficulty in Walking:

Pigs affected by bush foot often exhibit lameness, showing reluctance to bear weight on the affected limb. They may limp or favor one leg over the other while walking. Lameness can vary in severity, ranging from a slight impairment in mobility to complete inability to use the affected limb.

Swelling and Inflammation of the Foot: Bush foot causes inflammation and swelling in the affected hoof. The affected area may appear red, swollen, and tender to the touch. Pigs may exhibit signs of pain when pressure is applied to the affected foot.

Increased Heat in the Affected Hoof Signals Bush Foot

Due to the inflammatory response, the affected hoof may feel warmer to the touch compared to the healthy hooves. This increased heat is an indication of the ongoing infection and inflammation within the hoof tissues.

Discharge or Pus from the Foot Is A Sign of Foot Rot

Pigs with bush foot may develop discharge or pus from the affected foot. This discharge is often thick and foul-smelling. It is an indication of the presence of infection and the body’s attempt to combat the bacteria.

Foul Odor from the Hoof Area Signals Infection

The bacterial infection associated with bush foot can produce a distinct foul odor emanating from the hoof area. This odor is a result of the breakdown of tissues and the release of metabolic byproducts from the bacteria.

It is important to note that the severity of symptoms can vary depending on the stage of infection and individual pig’s response to the condition. Early detection of these symptoms through regular hoof inspections and close observation of pig behavior can significantly contribute to timely treatment and better outcomes.

• Pigs are hesitant to stand
• Hind legs appear lame
• Walking on the tip-toes or knees
• A warm, swollen claw
• An abscess (in some cases)

Causes of Bush Foot

Bush foot is caused by a cut, puncture wound, or cracked skin around the pig’s hoof area that gets infected. Rough floors, poor quality concrete with rough surfaces, and old stalls with sharp edges can contribute to bush foot. Pigs with a biotin deficiency are at a greater risk of bush foot. 

Bush foot is caused by a claw infection that has become inflamed and swollen around the coronary band (just above the hoof) and in the toes. Generally, the infection enters through a cut or piercing in the pig’s foot and spreads through the hoof and claw. 

Adding straw bedding can help to prevent bush foot in sows. Make sure pigs are getting enough biotin in their diets. Wash and disinfect concrete surfaces and check for broken boards, rough areas, or nails sticking out in the stalls. A safe and clean area will help keep your sow from developing bush foot. 

Treating Bush Foot

Treating bush foot in pigs involves a comprehensive approach that combines veterinary care, medication, and management practices. Prompt intervention is crucial to alleviate pain, control infection, and promote the healing process. Here are the primary treatment options for bush foot in pigs.

Treat Bush Foot by administering oral antibiotics as soon as possible to prevent an abscess from forming (if one hasn’t already). If the abscess has already developed, an urgent debridement will need to be done to drain the pus. 

Anti-inflammatory injections will help reduce the swelling and help with the pain. These injections will help heal the pig from the inside.

Footbaths (containing 1% formalin) will also treat the infection. Your pig must be walked through the bath once a week until the infection has cleared. Unfortunately, if antibiotic treatment is unsuccessful, the pig’s leg will need to be amputated to prevent death from septicemia.

Isolate Affected Pigs

The first step in treating bush foot is to isolate affected pigs from the rest of the herd. This helps prevent the spread of infection to other animals and allows for focused treatment and monitoring of individual cases.

Veterinary Intervention

Consultation with a veterinarian experienced in swine health is essential. The veterinarian will assess the severity of the condition, provide a specific diagnosis, and recommend an appropriate treatment plan tailored to the individual pig’s needs.

Medication for Bush Foot

Antibiotics are commonly prescribed to combat the bacterial infection associated with bush foot. The choice of antibiotics will depend on the specific bacteria involved and the results of bacterial culture and sensitivity testing. It is important to administer the prescribed antibiotics as directed by the veterinarian and complete the full course of treatment.

Topical Treatments for Foot Rot

Alongside systemic antibiotics, topical treatments may be recommended to aid in the healing process. These treatments can include antimicrobial sprays or ointments that help control bacterial growth and provide localized relief. They may also contain ingredients to promote tissue regeneration and hoof health.

Hoof Trimming to Prevent and Heal Bush Foot

Proper hoof trimming is essential for managing bush foot. Trimming helps remove damaged and infected tissues, allowing for better healing and preventing the spread of infection. Hoof trimming should be performed by a skilled professional or under the guidance of a veterinarian to avoid causing further injury or pain to the pig.

Maintaining a Healthy Environment

Improving hygiene and sanitation within the pig housing environment is crucial to prevent reinfection and promote healing. This includes ensuring clean and dry bedding, regular removal of manure, and adequate ventilation to minimize moisture buildup.

Supportive Care For Pigs with Bush Foot

Additional supportive measures may be necessary to aid in the recovery of pigs with bush foot. This can include providing appropriate pain relief medications, ensuring a balanced diet with adequate nutrition, and creating a comfortable, stress-free environment promoting rest and recovery.

Regular monitoring and follow-up with the veterinarian are essential during the treatment phase to assess the pig’s progress and make any necessary adjustments to the treatment plan. With timely and comprehensive treatment, pigs affected by bush foot can experience relief from pain, improved mobility, and a quicker recovery.
