Proceedings of 15th Symposium and 7th Conference on Lameness in Ruminants
Conference on Lameness in Ruminants edition:7 location:Kuopio, Finland date:9-13 June 2008
The objective of this research is to develop and analyze image parameters correlated with expert gait scores that are applicable for lameness detection in dairy cattle. Experiments were done on a commercial farm near Ghent Belgium in January-March 2008. A camera recorded the hoof movements of lactating Holstein cows from a distance of 1.5m. The ankle angle was calculated for 63 cows. Within the calculations it was proven that the parameter contains information that can be related to lameness. First results show a relation to gait scores given by experts. It shows also that the ankle angle is useful for lameness detection but future investigations should focus on the development of the ankle angle over time in an individual cow. A further goal is to build an automatic on-line lameness detection tool after analyzing more cows individually and more image parameters.
