Lameness is one of the most persistent welfare and cost problems in dairy farming. It is also one of the hardest to catch early. By the time a cow's gait is obviously abnormal, she has often been in pain for days, and the outcome for her, and the herd, is already worse than it needed to be.
A new randomised controlled trial from the University of Liverpool, published in the Journal of Dairy Science, has tested what happens when CattleEye is added to a working lameness management programme. The results are the strongest independent evidence yet that automated mobility monitoring changes outcomes for cows, not just for spreadsheets.
How the trial worked
Researchers followed 419 cows on a large commercial dairy farm in England. Every cow already benefited from the farm's standard care, routine hoof trimming and staff checks for obvious lameness. Half the herd, 211 cows, also had weekly CattleEye scoring added on top. Any cow flagged by the system was scheduled for a foot inspection and treatment. The other 208 cows continued on the standard protocol alone.
What the researchers found
The cows monitored by CattleEye were far less likely to develop severe lameness, 2% compared with 7.9% in the control group, and far less likely to become chronically lame, 3.9% against 9.8%. By mid-lactation, more of the CattleEye-monitored cows had healthy, lesion-free feet, 22.4% compared with 12%, and fewer had moderate lesions.
Importantly, these cows were not simply trimmed more often. They were trimmed more precisely, with treatment directed at the animals who actually needed it. Milk yield and culling risk were unchanged between the two groups, which shows that is a strong welfare result.
Why this matters
CattleEye has always been built on a simple idea that a camera scoring every cow, every day can perform on par with a trained mobility scorer, but is present 365 days a year in a way no human team can be. This trial, run independently by University of Liverpool researchers and peer-reviewed for the Journal of Dairy Science, show how this mission supports real treatment decisions and real animal outcomes, not just detection accuracy.
In addition to this independent evidence, CattleEye has now performed tens of millions of lameness checks, that consistently, objectively monitoring changes in hoof health and animal welfare.
