Lameness is one of the biggest health and welfare challenges on Irish dairy farms. A lame cow is in pain, less willing to walk, and more likely to spend less time feeding or showing signs of heat. As a result, lameness impacts milk yield, fertility, and can even shorten the productive life of the cow.
The Importance of Mobility Scoring

Why mobility scoring matters
Early detection is key. If lameness is caught at an early stage, treatment is far more successful. Mobility scoring is the most reliable way to pick up cows that are only just starting to go lame, before they become very obvious to the eye.
What is mobility scoring?
Mobility scoring is simply watching cows walk and giving them a score based on how easily and comfortably they move. A number of scoring systems exist; one straightforward system widely used in the UK is the AHDB 0 – 3 scale:
| Score | Description | Action |
|---|---|---|
| 0 | Walks freely with no signs of lameness | No treatment required. Continue routine scoring. |
| 1 | Slightly imperfect gait, but mobility not affected | Monitor closely. Re-check at the next scoring session or sooner if the cow deteriorates. |
| 2 | Impaired mobility, clear signs of lameness with shortened stride or uneven weight bearing | Examine and treat as soon as is practically possible. Record the case and involve vet or hoof trimmer if needed. |
| 3 | Severely impaired mobility, cow is very lame and may be reluctant to walk | Treat immediately. Provide pain relief, seek veterinary input, and keep in comfortable housing until recovery. |
Regular scoring means cows are picked up and treated before problems become severe, protecting welfare and reducing losses. The AHI Hoof HealthCheck Technical Working Group are currently producing a farmer video to demonstrate how to carry out mobility scoring, which will be available in the coming months.
Benefits of regular mobility scoring
Benefits of regular mobility scoring
- Improves recovery rates: Early identification means more cows recover fully, with less risk of permanent hoof damage.
- Saves money: Prompt treatment reduces milk losses, improves fertility, and lowers the risk of early culling.
- Supports herd management: Herd-level scores give a clear picture of how common lameness is and whether things are improving or worsening.
- Helps your vet and trimmer: Mobility scoring allows identification of cows that need treatment/trimming.
Increased general foot health awareness: Motivates farm staff to improve herd mobility and therefore overall herd health.
How often?
Monthly scoring is recommended. It does take time and effort, but farmers who commit to doing it regularly see the benefits in terms of healthier cows, improved fertility, and better overall herd performance. Building it into routine management turns that investment of time into a real return.
Key point
Mobility scoring takes some time, but it is straightforward once you know the system and delivers big benefits. By detecting lameness early, you can protect cow comfort, reduce costs, and cut down on extra work later on.
