Records of claw trimmings were analyzed in seven organic and six conventional Danish herds (a total of 974 cows). The housing systems represented were tie stall systems, loose housing system with slatted floor (one organic herd), and deep litter systems (deep straw bedding). Occurrence of sole disorders was analyzed separately for cows in first lactation and for cows in later lactations. Three different responses (acute haemorrhage, sole ulcer in one leg and sole ulcer in two or more legs) were analyzed using three binomial logistic regression analyses for each group. Herd analyzed as a fixed effect was a strong risk factor for all kinds of sole ulcer. Lactation stage was a risk factor for acute haemorrhage in both groups of cows, and for sole ulcer in first parity cows. In general, there was a strong positive association between the period 61-120 d post partum and the presence of sole disorders. Breed was associated with acute haemorrhage in cows in second and later parities, and sole ulcer in one leg only in first parity cows in an interaction with lactation stage in both conditions. Danish Friesian cows were strongly associated with sole disorder, although the combination of lactation stage from 61 to 120 d post partum in cows of other dual purpose breeds was positively associated with the presence of sole ulcer in one leg only in first parity cows. The time of year for claw trimming was a risk factor for acute haemorrhage in first parity cows, with the period from December to January most strongly associated with acute haemorrhage. Previous disease treatment was a risk factor for sole ulcer in two or more legs in second and later parities. Udder related disorders and disorders other than reproductive problems were positively associated with the occurrence of sole ulcer. Body weight at calving was associated with acute haemorrhage in cows in second and subsequent parities. Body weight lower than the mean herd level by > 50 kg was negatively associated with acute haemorrhage.
