Hypothesis
Does local anaesthesia and analgesia reduce pain responses in piglets during castration?
Conclusion
Lidocaine reduces pain during castration, and meloxicam reduces pain-related behaviour after castration.
Supporting Evidence
- Piglets given lidocaine had lower vocalisation intensity during castration.
- Meloxicam reduced pain-related behaviours the day after castration.
- Controls had less swollen wounds compared to treated piglets.
- Piglets treated with meloxicam had lower serum amyloid A concentrations.
Takeaway
This study shows that giving piglets medicine before and after castration can help them feel less pain.
Methodology
Piglets were randomly assigned to four treatment groups: no anaesthesia, analgesia, local anaesthesia, or both, and their pain responses were measured during and after castration.
Potential Biases
The technicians performing measurements were not blinded to the treatments.
Limitations
The study was conducted in a limited number of herds and may not represent all piglet castration practices.
Participant Demographics
Male piglets from five herds, aged 1-7 days at the time of castration.
