Cattle Feedlot Lameness Management

Lameness in feedlot cattle is a major welfare problem caused by multiple interacting factors including diet, housing, and management practices.

Key Facts

Feedlot lameness prevalence ranges from 1-5% of cattle at any time, with higher rates in some systems
Laminitis from grain-induced acidosis is the primary metabolic cause of feedlot lameness
Digital dermatitis (Mortellaro disease) is a contagious bacterial skin disease causing painful lameness
Foot rot (interdigital necrobacillosis) causes sudden severe lameness from bacterial infection between the claws
Feedlot pens with deep mud around water sources and feed bunks increase foot rot and digital dermatitis risk
Prompt treatment of lame cattle significantly reduces duration of welfare compromise and economic loss

Welfare Considerations

Feedlot lameness causes significant welfare harm through the pain of weight-bearing on compromised feet, reduced ability to compete at feed bunks in group-housed settings, and in severe cases, recumbency with associated pressure sores and secondary complications. Lame feedlot cattle cannot express normal feeding, social, and rest behaviors in ways that compound the primary welfare harm. The connections between feeding management (preventing acidosis), housing management (reducing mud burden and environmental contamination), and veterinary care (prompt treatment of acute lameness) require integrated herd health approaches rather than purely individual animal treatment. Reducing acidosis risk through transitional feeding programs and maintaining pen hygiene around water and feeding areas addresses root causes.

What You Can Do

Implement a gradual step-up feeding program to reduce acidosis and associated laminitis risk
Maintain pen hygiene particularly around water sources and feed bunks to reduce foot rot and dermatitis
Train feedlot staff to recognize lameness signs early and pull lame cattle for treatment within 24 hours
Use foot bathing programs with zinc sulfate or copper sulfate to reduce digital dermatitis spread
Ensure appropriate analgesia (flunixin) is provided for acute lameness treatment
Monitor lameness prevalence as a welfare KPI and investigate farms significantly above industry benchmarks
