Research Paper Web Link / URL:
The relationship between outward rotation of hind feet and subclinical sole lesions was analysed in 117 lactating Holstein cows housed in free stalls. The outward rotation was visually classified as score 1 (none to slight rotation) and score 2 (moderate to severe rotation), and the degree of external rotation, dimensions of medial and lateral claws and sub-clinical sole lesions of the right hind feet were measured. The prevalence and severity of haemorrhage in the sole were higher in the lateral claws with rotation score 2 than those with rotation score 1, while the dimensions of the medial and lateral claws were not different. It is suggested that moderate to severe rotation of the hind feet may be related to the prevalence and severity of haemorrhage in the sole of the lateral claw
