[Experiences with pain control during piglet castration in Switzerland Part 1: Inhalation anesthesia]

Area of Science:

• Veterinary Medicine
• Animal Welfare Science
• Agricultural Safety

Context:

• Castration is a common procedure in swine farming.
• Inhalational anesthesia is explored as a method for pain management during castration.
• Assessing animal welfare, workplace safety, and time efficiency is crucial for practical implementation.

Purpose:

• To describe the practical implementation of painless castration under inhalational anesthesia.
• To objectively assess animal welfare, workplace safety, and time exposure during this procedure.
• To evaluate the feasibility and challenges of using inhalational anesthesia for swine castration.

Summary:

• A study involving 600 farmer questionnaires and 100 farm visits assessed castration under inhalational anesthesia.
• Results indicate that 44% of farmers used analgesics, 14% of piglets showed insufficient anesthesia, and 18% had increased bleeding.
• Farmer-reported health issues (headache, dizziness) were noted in 22%, with some exceeding safety limits for isoflurane, and the procedure took longer than traditional methods.

Impact:

• The study highlights potential improvements in animal welfare but also identifies drawbacks like increased time, costs, and farmer safety concerns.
• Findings suggest that current compensation for farmers does not adequately cover the additional expenses and time associated with this anesthetic technique.
• Further research and protocol refinement are needed to optimize painless castration methods for swine, balancing animal welfare with economic and safety considerations.
