Ultrasonographic Screening of Dairy Cows with Normal Uterine Involution or Developing Postpartum Uterine Disease Using B-Mode, Color, and Spectral Doppler

Table 1

The study included epidemiological data of cows with normal calving and healthy postpartum from high-altitude tropical dairy herds.

Group	Number of cows	Parity			DIM
	n	Mean ± SEM	Min	Max	Mean ± SEM	Min	Max
Healthy cows	26	2.65 ± 0.4	1	7	36.9 ± 17.9	2	70
Cows suffering Met	4	5.25 ± 0.9	3	7	12.0 ± 2.5	7	18
Healthy matched to Met	3	2.0 ± 0.6	1	3	12.3 ± 3.9	7	20
Cows suffering CE	7	3.9 ± 0.7	1	6	35.7 ± 6.3	24	69
Healthy matched to CE	7	1.9 ± 0.3	1	3	34.4 ± 4.6	24	55
Cows suffering SE	5	1.4 ± 0.2	1	2	52.2 ± 7.8	35	71
Healthy matched to SE	5	3.4 ± 0.9	2	6	50.4 ± 6.9	35	68

Cows affected by Met, CE, or SE were matched by farm and DIM to healthy cows ( > 0.05). DIM, days in milk. Met, metritis. CE, clinical endometritis. SE, subclinical endometritis.
