Objective: This study evaluated the cervical sampling as an easy and safe method for the
diagnosis of subclinical endometritis in dairy cattle.
Methods: One hundred ninety seven lactating Holstein cows were examined at 26–32 d
in milk (DIM) for diagnosis of endometritis. Differential cellular counts were also made
from stained smears of the cervical mucosa. Using the Receiver/Response Operating
Characteristics (ROC) curve, presence of >17.5% polymorphonuclear (PMN) cells was
calculated for detection of subclinical endometritis with sensitivity and specificity of
56.5% and 83.3% respectively.
Results: Cows with subclinical endometritis had significantly more open days and all
service conception rate than normal cows. The results of survival analysis showed that
normal cows became pregnant at a significantly faster rate than cows with subclinical
endometritis.
Conclusions: The results of the present study introduced the cervical smear sampling as
an easy and suitable method for diagnosis of subclinical endometritis in dairy cattle.
