Feed refusal during ochratoxicosis in turkeys.

S J Burditt, W M Hagler, P B Hamilton

    Poultry Science
    |November 1, 1984
    PubMed
    Summary

    Young turkeys refused feed contaminated with ochratoxin A, but chickens did not. This indicates ochratoxicosis is an emerging poultry problem, with species-specific responses to mycotoxins.

    Area of Science:

    • Veterinary Toxicology
    • Poultry Science
    • Mycotoxicology

    Background:

    • Field outbreaks of ochratoxicosis in turkeys showed feed refusal, unlike in chickens, suggesting species-specific responses.
    • Laboratory models for poultry feed refusal syndromes have recently been developed.

    Purpose of the Study:

    • To evaluate the species-specific responses of turkeys and chickens to ochratoxin A exposure.
    • To determine if feed refusal is a consistent symptom of ochratoxicosis in poultry.

    Main Methods:

    • Young turkeys and chickens were fed diets containing graded concentrations of pure ochratoxin A.
    • Feed consumption was monitored to assess feed refusal and intake.

    Main Results:

    • Pure ochratoxin A significantly reduced feed consumption in young turkeys.
    • Young chickens did not exhibit feed refusal when fed graded concentrations of ochratoxin A.

    Conclusions:

    • Feed refusal is a symptom of ochratoxicosis in turkeys, but not in chickens.
    • Ochratoxicosis is an emerging concern in the poultry industry, with significant species-specific differences in response to ochratoxin A.
