Locomotion scoring is an important tool to detect dairy cow lameness. A number of locomotion scoring systems use the posture of the back to identify lame cows (score 3). For example Sprecher et al (1997) suggested the presence of an arched back standing and walking indicates lameness. Flower and Weary (2006) developed this system to score cows while walking where a score 3 cow has a more severely arched back than a score 2 cow. However to date no work has been published characterising the degree of arching of the spine observed in lame animals and its relationship with foot lesions. This is important in the early detection of lameness and could be incorporated into locomotion scoring systems to improve the objectivity. The aim of this study was to assess the effect of foot lesions on spine posture of Holstein dairy cows in early lactation by motion analysis.
