Lameness is one of the most significant issues affecting dairy cattle, compromising health and welfare and impacting on fertility and productivity. Our award-winning Lameness Detection module gives you the key information you need to help you reduce the number, severity and duration of lameness cases.

CowAlert monitors and analyses each cow’s daily mobility to create a unique lameness status for each animal. Lameness Alerts are generated daily to help you identify and prioritise issues and intervene early. All the data is securely stored to build up a detailed history of your herd. A simple herd-level overview graph lets you quickly identify trends over time and monitor the impact of management changes.


3rd most important

Lameness has been identified as the third most important health-related economic loss, after fertility and mastitis.

(*Bruijnies et al., 2010)

Lameness Alerts

4.6% Lower Yield

Mobility score 3 cows have a 4.6% lower milk yield than a score 0 cow.

(O’Connor et al., 2020 )


£320 PER COW

Average cost of lameness case, £320 per cow.

(Willshire & Bell, 2009)


270 – 857KG

Lameness reduces milk production by between
270 – 857kg per lactation. The reduced milk production may occur up to 5 months after treatment for lameness!

(Huxley, 2013)



A lame cow on average produces 8 litres of milk less per day compared with
non-lame cows.

(Blackie et al., 2011)

How Do Lameness Alerts Work?

lameness alerts

Daily Lameness Alerts provide a quick overview of the lameness status of your herd and help you prioritise actions through easy colour coding identification:
Red: Cows with a high probability of being lame and should be investigated
Amber: Cows with a medium probability of being lame and should be monitored
Blue: Cows that have been diagnosed as lame
Green: Cows with a low probability of being lame
Improving cows: Identifies cows whose lameness probability has decreased, or stayed the same this week, against last week’s average.
Deteriorating cows: Identifies cows whose lameness probability has increased this week against last week’s average.

What’s Reported?

CowAlert’s last 7-day list allows you to investigate your herd’s new lameness alerts and the new orange lameness alerts, allowing for early intervention. Within this new feature, you can manage your herd’s lameness alerts more efficiently by adding the cow onto a vet or foot trimmer list which can then be emailed or printed if required.

Once a cow is on the vet list and subsequently seen by the vet, they can be moved onto the treated list. CowAlert records this treatment process for future analysis. Similarly, the foot trimmer list can be accessed from the alert status page but allows for more detailed diagnostic feedback. The feedback from the foot trimmer can be inputted into CowAlert detailing the location of the lameness issue along with the diagnosis, date and any relevant notes, such as treatment provided.

CowAlert’s individual cow lameness history allows you to examine the lameness status of each cow. Including the daily lameness probability for a single cow, compared with her 7 day rolling lameness probability and the herd average. The Herd Overview provides the herd lameness history, enabling you to easily spot trends and see the impact of a particular action on the farm, such as hoof-trimming. Each cow’s daily lameness status is stored, building up a picture over time of herd lameness. This provides a quick overview of the proportion of lame and healthy cows.
