Description
Summary:•The prevalence of sole haemorrhages was evaluated in a large sample of dairy breed bull calves shortly before slaughter.•Of 730 calves examined, 74.7% had sole haemorrhages and 16.3% had severe sole haemorrhages.•The odds of having a sole haemorrhage was more than twice as high when housed on concrete floors than deep litter straw.•A higher daily weight gain was associated with a higher odds of having severe sole haemorrhage. To evaluate the prevalence of sole haemorrhages among Danish dairy breed bull calves and associated risk factors, 730 calves were hoof trimmed shortly before slaughter and the presence of sole haemorrhages was recorded. Associations between the outcomes sole haemorrhages and severe sole haemorrhages, and the explanatory variables daily weight gain, liver abscesses and flooring, were analysed. Of the 730 calves, 545 (74.7%) had sole haemorrhages and 119 (16.3%) had severe sole haemorrhages. Calves housed on slatted concrete floors with cubicles had higher odds of sole haemorrhages (odds ratio, OR, 2.69, 95% confidence interval, CI, 1.81–4.00; P
