@article{Nam_2020, title={Risk factors for prolonged postparturient vaginal discharge in sows}, volume={50}, url={https://he01.tci-thaijo.org/index.php/tjvm/article/view/243257}, abstractNote={<p><span class="fontstyle0">Previous study has shown that excessive postparturient vaginal discharge in sows causes impaired reproductive<br>performance in the subsequent litter. This observational study aimed to investigate the effects of categorical predictors<br>(farm (1-7), assisted farrowing, parity number (1, 2-5, &gt;5) and stillbirth) and continuous predictors (farrowing duration,<br>litter size and postparturient body temperature) on the incidence of prolonged postparturient vaginal discharge<br>(duration of postparturient vaginal discharge &gt;5 days) in sows. Data was collected from 620 postparturient sows raised<br>on 7 farms in 4 provinces in Vietnam. Univariate logistic regression analysis was used to identify the potential risk<br>factors for prolonged postparturient vaginal discharge. All risk factors that had a P-value &lt;0.15 in the univariate<br>analysis were selected for multivariate logistic regression analysis. The average farrowing duration, litter size, incidence<br>of stillbirth at litter level and incidence of assisted farrowing were 4.0±1.7 h, 12.1±2.9, 39.4% and 32.9%, respectively.<br>The duration of postparturient vaginal discharge was 4.3±0.9 days. The incidence of prolonged postparturient vaginal<br>discharge was 12.6% (78/620). Multivariate logistic regression analysis revealed that the risk factors for prolonged<br>postparturient vaginal discharge were assisted farrowing (RR=2.40, P&lt;0.001), increased farrowing duration (RR=1.17,<br>P=0.038), parity &gt;5 (RR=2.57, P=0.001) and stillbirth (RR=1.93, P=0.009). In conclusion, prolonged postparturient<br>vaginal discharge was common in sows. Assisted farrowing, increased farrowing duration, parity &gt;5 and stillbirth were<br>risk factors for prolonged postparturient vaginal discharge.</span> </p>}, number={1}, journal={The Thai Journal of Veterinary Medicine}, author={Nam, Nguyen Hoai}, year={2020}, month={Apr.}, pages={57–63} }
