Description
Corrales-Hernández and colleagues studied how caffeine combined with a birth-inducing hormone affects sows during farrowing, comparing first-time mothers with experienced ones in a 2026 animal study. Pig research usually centers on piglets, leaving the sow's own response understudied, even though intravulvar caffeine is authorized in Europe. The team measured hormones, behavior, and delivery performance under different induction protocols.
Corrales-Hernández found that a split-dose hormone protocol plus caffeine clearly shortened total farrowing time and the intervals between piglets in both parity groups, increased piglets born alive. Reduced perinatal deaths, especially in experienced sows. Treated sows also changed posture less often, a sign of discomfort, and rested more in favorable lying positions. Stress and reproductive hormone patterns during birth depended strongly on whether the sow had given birth before, showing the maternal response is parity-driven and the combination a useful welfare tool.
