Trichophytobezoars in miniature swine

P L Jepsen, C C Middleton, E C Stephens

    Journal of the American Veterinary Medical Association
    |November 1, 1977
    PubMed
    Summary

    Miniature swine developed gastric trichophytobezoars due to indoor concrete confinement and pelleted feed consumption. Surgical intervention (gastrotomy) successfully treated the condition, preventing debilitation and improving swine health for research.

    Area of Science:

    • Veterinary Medicine
    • Animal Science
    • Gastroenterology

    Background:

    • Gastric trichophytobezoars are a significant health concern in miniature swine.
    • Confinement husbandry and direct feed consumption from concrete floors predispose swine to bezoar formation.
    • Bezoar development can lead to weight loss, debilitation, and premature death, threatening research viability.

    Purpose of the Study:

    • To investigate the cause and effect of gastric trichophytobezoars in miniature swine.
    • To evaluate the efficacy of surgical intervention for treating trichophytobezoars.
    • To identify husbandry practices contributing to bezoar formation.

    Main Methods:

    • Observation of miniature swine housed indoors on concrete floors.
    • Analysis of husbandry practices, including feeding methods.
    • Surgical gastrotomy performed on affected sows and boars.

    Main Results:

    • Miniature swine developed gastric trichophytobezoars, leading to weight loss and debilitation.
    • Surgical gastrotomy in 8 affected animals (3 sows, 5 boars) resolved the condition.
    • Clinical improvement and avoidance of starvation were observed post-surgery.

    Conclusions:

    • Indoor concrete confinement and direct pelleted feed consumption are predisposing factors for gastric trichophytobezoars in miniature swine.
    • Gastrotomy is an effective treatment for gastric trichophytobezoars, improving clinical outcomes.
    • Modifying husbandry practices may prevent trichophytobezoar formation in research swine.
