Single-step genome-wide association analyses of claw horn lesions in Holstein cattle using linear and threshold models

Table 3 Prevalence (%) and average lesion severity of sole haemorrhage (SH), sole ulcers (SU), and white line disease (WL) at each lactation stage (pre-calving stage, calving stage, early lactation stage, and late lactation stage) in the studied population

Lesion		Pre-calving	Calving	Early	Late	Overall
SH	Prevalence (%)	32.5%	33.0%	57.5%	52.9%	83.0%
SH	Average lesion severity^a	0.140	0.189	0.328	0.269	–

^aThe lesion severity of an individual was calculated as the average lesion score of all assessed feet of an animal
