Effects of intravenous oxytocin on plasma serotonin and trainability in horses

Key Points

• Plasma serotonin levels increased following intravenous oxytocin administration, affecting equine behavior.
• Analysis revealed significant changes in trainability metrics, highlighting oxytocin's role in learning processes.
• Observational analysis showed variability in responses due to individual differences in the horses' temperament.
• These findings suggest oxytocin could be explored further for training applications in equines.
