Correlation analysis evaluates how umbilical cord traits and farrowing duration influence reproductive performance in sows, indicating ways to enhance viability.

Key Points

The research aims to evaluate how umbilical cord diameter and farrowing duration impact reproductive performance in sows.
Analyzed data from sows of different parities on commercial farms
Checked relationships between litter characteristics, faecal scores, and farrowing traits
Evaluated umbilical cord artery and vein diameters and their impacts on reproductive metrics
Fourth- and sixth-parity sows produced more healthy piglets than first-parity sows
Higher umbilical cord vein diameters linked to increased live birthweights
Shorter farrowing intervals correlated with higher live-born piglet counts
Prolonged farrowing duration was associated with increased perinatal mortality
Faecal scores above 3.00 linked to healthier piglet outcomes
