This study evaluated an immunological skin test in piglets to assess allergy susceptibility. A histamine skin test showed potential for identifying piglets prone to allergic states.

Area of Science:

  • Veterinary Immunology
  • Dermatology
  • Swine Medicine

Context:

  • Allergies and hypersensitivity reactions are significant concerns in swine health and production.
  • Accurate diagnostic tools are needed to identify susceptible animals early.
  • Skin testing is a common method for evaluating immune responses.

Purpose:

  • To assess the utility of a simple immunological skin test in weaned piglets.
  • To evaluate dermal reactions to histamine, phytohaemagglutinin, and staphylococcus lysate.
  • To determine if skin test responses can predict susceptibility to allergic states.

Summary:

  • Seventy-three piglets underwent intradermal injections of sodium chloride, histamine, phytohaemagglutinin (PHA), and staphylococcus lysate (STAVA).
  • Dermal reactions (papule size at 20 min, induration size at 24/48 h) were measured.

  • A histamine papule size exceeding 15 mm (corrected for saline control) indicated potential allergy susceptibility.

    • Impact:

    • This study introduces a potential method for early identification of allergy-prone piglets.
    • Findings may aid in managing herd health and reducing economic losses due to allergies.
    • Further research could refine this skin test for routine veterinary diagnostics.
