    Abstract:
    Claw health and lameness data from five dairies with compost bedded barns (n = 201 data sets) were evaluated and compared with data from five dairy herds housed in freestall cubicle barns (n = 297 data sets). They were matched for having the same cow numbers, flooring type and similar milk yield. The prevalence of lameness, claw lesions and their severity grades were analysed. Two claw health indicators, the cow claw score (CCS) and the farm claw score (FCS), were calculated using a computerised claw trimming database programme; there was no significant difference in overall lameness prevalence in cows from five compost bedded barns (18.7%) compared to cows from five freestall cubicle herds (14.9%). A cumulative link mixed model (CLMM) did not show significant differences in locomotion between different types of bedding material, flooring system, breed, visit number, observer and time since last trimming, but locomotion was significantly influenced by CCS. Another CLMM tested the impact of parameters mentioned on CCS and showed significant influence of flooring type, visit number and cattle breed. Statistically significant differences in the prevalence of claw disorders between compost bedded and freestall cubicle barns were found for white line disease (WLD; 20.4% and 46.6%, respectively), heel horn erosion (HHE; 26.9% and 59.9%, respectively), concave dorsal wall as a result of chronic laminitis (6.5% and 15.9%, respectively) and for interdigital hyperplasia (0.2% and 3.1%, respectively). The results of this study indicate that compost dairy barns are a good alternative to common cubicle housing systems in terms of lameness, claw health and animal welfare.
