The researchers say the effectiveness of cheaper devices could result in wider use amongst farmers, vets and hoof trimmers helping to identify lameness earlier.
The study, led by RVC undergraduate veterinary student, Aidan Coe, alongside Dr Nicola Blackie, a senior lecturer in Production Animal Science at the RVC, compared the thermal images of 83 cows’ hind feet, captured with both high and low cost thermal imaging devices.
Very little difference was identified in the performance and quality of the devices despite the low-cost device being 2% the cost of the high cost device.
Images captured suggested that low-cost thermal imaging devices would be the most cost-effective choice to aid in the identification of lameness.
This study highlights the effectiveness of cheaper infrared thermal imaging devices in identifying the condition which has the potential to lead to the wider use of the devices by farmers, vets and hoof trimmers, in turn allowing the condition to be identified earlier.
Whilst high-cost devices have sometimes been used to detect lameness in cattle, the price point of up to £20,000 and fragility has previously limited their usefulness in a farm setting.
Aidan Coe, Undergraduate Veterinary Student at the RVC, and lead researcher on this paper, said: “There is a possibility that low-cost infrared thermal imaging devices could be used as an objective, cost-effective method of assessing the lameness of the national herd, which may prove a useful adjunct to the current lameness detection methods.”
