What Is Foot Rot?
Foot rot is a bacterial infection of the tissue between the toes. It's one of the most common causes of lameness in cattle, and it costs the industry millions annually in reduced weight gain, treatment costs, and culling.
A lame cow eats less, gains less weight, produces less milk, and is harder to breed. If left untreated, foot rot can become chronic and lead to permanent lameness , meaning the animal needs to be culled.
How to Identify Foot Rot
Early detection is critical. The sooner you treat, the faster the recovery and the less production you lose.
Early Signs
- Lameness: The animal is limping or favoring one foot. She may walk on the toe of the affected foot to avoid putting pressure on the infected area.
- Swelling: The area between the toes swells and becomes inflamed. The swelling may extend up the foot.
- Separation of the toes: As swelling increases, the toes spread apart. This is a classic sign of foot rot.
- Discharge: A foul-smelling, grayish discharge may ooze from between the toes. The smell is distinctive , once you've smelled it, you'll recognize it.
Advanced Signs
- Severe swelling: The entire foot and lower leg may swell.
- Fever: The animal may develop a fever as the infection spreads.
- Refusal to bear weight: The animal won't put any weight on the affected foot.
- Abscess formation: Pus-filled pockets may form in the tissue.
Treatment
Immediate Care
- Isolate the animal. Move her to a clean, dry pen with soft bedding.
- Clean the foot. Wash the affected foot with clean water and mild antiseptic solution.
- Trim the foot. If possible, trim away dead tissue between the toes to expose the infection to air and medication.
- Apply topical treatment. Zinc sulfate solution (10%), copper sulfate solution, or a commercial foot rot spray applied directly to the affected area.
Systemic Treatment
For moderate to severe cases, antibiotics are necessary:
- Oxytetracycline (LA-200): Common, effective, and relatively inexpensive. Follow label dosage.
- Penicillin: Effective for foot rot. Requires daily dosing for several days.
- Ceftiofur (Excede, Naxcel): Longer-acting options that require fewer doses.
Important: All antibiotics have withdrawal periods. Record the drug, dose, date, and withdrawal end date. Don't sell the animal before the withdrawal period expires.
When to Call the Vet
- The animal doesn't improve within 3-5 days of treatment
- The infection appears to be spreading beyond the foot
- The animal develops a high fever
- You suspect a deeper infection (deep tissue, joint, or bone involvement)
- Multiple animals are affected simultaneously (possible contagious outbreak)
Prevention
Environmental Management
- Keep feeding areas dry. Foot rot bacteria thrive in wet, muddy conditions. Improve drainage around feed bunks and water troughs.
- Provide dry bedding. Cattle standing in wet manure or mud are more susceptible.
- Rotate pastures. Avoid overgrazing, which leads to muddy conditions.
- Remove sharp objects. Rocks, wire, and metal debris can puncture the hoof and introduce bacteria.
Nutritional Prevention
- Copper supplementation: Adequate copper intake supports hoof health. Have your forage tested and supplement accordingly.
- Zinc supplementation: Zinc is critical for hoof integrity. Many mineral supplements include zinc.
- Biotin: Some research supports biotin supplementation for hoof health, though results in cattle are less dramatic than in dairy cows.
Regular Foot Care
- Inspect feet at processing. Every time an animal is in the chute, check her feet.
- Trim overgrown hooves. Long hooves trap bacteria and create pockets for infection.
- Footbaths: In confined operations, a zinc sulfate or copper sulfate footbath can reduce incidence.
Chronic Foot Rot
Some animals are prone to recurrent foot rot. If an animal gets foot rot more than 2-3 times per year, consider culling her. Chronic foot rot is difficult to cure permanently, and the animal is a recurring source of infection for the herd.
Record and Track
Record every foot rot case: animal ID, date, treatment given, withdrawal dates, and outcome. This data helps you identify:
- Which animals are prone to foot rot (cull candidates)
- Which pastures or pens have the highest incidence (environmental issues)
- Which treatments work best in your operation
QualityHerd lets you log lameness and foot rot cases, track treatments and withdrawals, and identify patterns over time.
Catch It Early, Treat It Fast
Foot rot caught in the first 24-48 hours almost always responds to treatment. Foot rot caught after a week can become chronic and may require amputation or culling. Check your cattle daily, and when you see lameness, investigate immediately.
