Relationship between herd-level incidence rate of energy-related postpartum diseases, general risk factors and claw lesions in individual dairy cows recorded at maintenance claw trimming

Table 2 Prevalence of claw lesions at trimmings in herds with different incidence rates of energy-related postpartum diseases

	High		Inconsistent-high		Low
	n	Prevalence (%)	n	Prevalence (%)	n	Prevalence (%)
Laminitis-associated lesion¹	1141	40	772	22	125	26
Sole ulcer	157	6	146	4	27	6
Sole haemorrhage	1071	38	674	20	110	23
Hygiene-related lesion	1160	41	931	27	108	23
Digital dermatitis	183	6	247	7	6	1
Heel-horn erosion	839	29	521	15	74	16
Other lesions²	446	16	283	8	42	9
Absence of any lesion	1229	43	2032	59	291	61

¹Observations of individual lesions do not sum to the number of lesions in disease complexes because cows could have multiple lesions per trimming.
²Other lesions include interdigital dermatitis, verrucose dermatitis, and interdigital hyperplasia.
