Polioencephalomalacia in goats.

M C Smith

    Journal of the American Veterinary Medical Association
    |June 15, 1979

    Summary
    This summary is machine-generated.

    Polioencephalomalacia in goats may be linked to thiamin deficiency. Affected goats showed reduced transketolase activity, indicating impaired thiamin-dependent metabolism, with some responding to thiamin treatment.

    Area of Science:

    • Veterinary Medicine
    • Animal Neurology
    • Biochemistry

    Background:

    • Polioencephalomalacia (PEM) is a neurological disease affecting goats.
    • Concentrate feeding is common in affected goats, particularly during winter and spring.
    • Thiamin (vitamin B1) is crucial for carbohydrate metabolism and neurological function.

    Purpose of the Study:

    • To investigate the role of thiamin deficiency in polioencephalomalacia in goats.
    • To assess thiamin-dependent enzyme activity in affected goats.

    Main Methods:

    • Six goats diagnosed with polioencephalomalacia were studied.
    • Three goats received thiamin therapy.
    • Transketolase activity was measured in two affected goats and nine healthy controls.

    Main Results:

    • Three of the six affected goats responded to thiamin therapy.
    • Three goats died within 2 to 7 days of symptom onset.
    • Affected goats exhibited significantly lower transketolase activity compared to controls.

    Conclusions:

    • Results suggest a potential link between thiamin deficiency and polioencephalomalacia in goats.
    • Reduced transketolase activity in affected goats supports impaired thiamin-dependent metabolism.
    • Thiamin supplementation may be a beneficial treatment for goat polioencephalomalacia.
