Dairy cows assigned to four treatment groups were administered PGF2 analogue (Cloprostenol) on day 8 (n=5), day 25 post partum (n=5), or antibiotic from day 1 to 5 postpartum (n=5), or kept as untreated control (n=5). The monitoring of endometrial thickness of previous gravid and non-gravid uterine horn was performed by transrectal ultrasound scanning on day 43 but there was no significant difference (p>0.05) found between treatment and control group. Endometrial cytology confirmed subclinical endometritis in cows under controlgroup based on the mean percentage of PMN cells. Similarly, PMN cells were statistically different (p<0.05) between PG8 and control group.
