Caprine aflatoxicosis: serum electrophoresis and pathologic changes.

D M Miller, J D Clark, R C Hatch

    American Journal of Veterinary Research

    Summary

    This study investigated aflatoxin B1 (AFB1) toxicity in goats, revealing significant pathologic changes including liver and lung lesions. Goats serve as a viable model for understanding ruminant aflatoxicosis.

    Area of Science:

    • Veterinary Toxicology
    • Ruminant Pathology

    Background:

    • Aflatoxin B1 (AFB1) is a mycotoxin with known toxicity in various animal species.
    • Understanding its effects in ruminants, specifically goats, is crucial for animal health and food safety.

    Purpose of the Study:

    • To determine the pathologic changes and serum electrophoretic patterns in goats exposed to aflatoxin B1.
    • To evaluate goats as a potential model for studying aflatoxicosis in ruminants.

    Main Methods:

    • Thirty male goats were administered oral aflatoxin B1 at four dosage levels (0.1, 0.2, 0.4 mg/kg/day) or a control.
    • Pathologic examinations and serum protein electrophoresis were conducted.
    • Clinical signs and necropsy findings were recorded.

    Main Results:

    Related Experiment Videos

    • Goats exposed to AFB1 exhibited ascites, pale livers, hemorrhages, icterus, and nasal discharge.
    • Microscopic findings included bile ductule proliferation, hepatocellular degeneration, pneumonia, rhinitis, and renal tubular nephrosis.
    • While serum gamma-globulins increased and beta-globulins decreased, these changes were not statistically significant (P > 0.05).
    • Lower AFB1 doses resulted in longer survival but more severe lesions.

    Conclusions:

    • Aflatoxin B1 induces significant multi-organ pathology in goats, including hepatic, pulmonary, and renal lesions.
    • Goats demonstrate susceptibility to aflatoxicosis and may serve as a suitable animal model for further research in ruminants.
    • The observed pathologic changes highlight the potential risks associated with aflatoxin B1 contamination in animal feed.
