Effect of metritis to duration of vaginal mucus discharge in postpartum of dairy cows

Abstract

The present study aimed to  investigate the duration of vaginal mucus discharge in postpartum of dairy cows and effect of postpartum metritis on duration of vaginal mucus discharge. The study was carried out in 218 dairy cows raising in Moc Chau district, Son La province and Duy Tien district, Ha Nam province.Vaginal mucus discharge was observed and the discharge period was recorded from the delivery time until finishing vaginal mucus discharge. The studied results showed that postpartum vaginal mucus discharge period in the dairy cows could be categorized into 2 stages: the stage of discharging pink colour mucus and the stage of discharging white colour mucus. The durations of these 2 stages in our study were 7.6 ± 2.8 days and 4.9 ± 1.7 days, respectively, and the total period of postpartum vaginal mucus discharge was 12.5 ± 3.2 days. In addition, metritis was identified as the risky factor that prolonged the postpartum vaginal mucus discharge time. Using combination of PGF2alpha, oxytoxin and catosal medicines for treatment could reduce the period of vaginal mucus discharge and the rate of metritis in the dairy cows.
