Muscovy ducklings, a particularly sensitive avian bioassay for T-2 toxin and diacetoxyscirpenol.
Day-old domesticated Muscovy ducklings (Cairina moshata) were given the trichothecene mycotoxins T-2 toxin or diacetoxyscirpenol at 0.25, 0.5, or 1 micrograms/g of feed for 7 days. All concentrations of both toxins caused characteristic dose-related lesions on the roof of the oral cavity of the birds. Muscovy ducklings showed these signs in a shorter time (less than 16 hours in some cases) and at a lower feed concentration of these trichothecenes than did other avian species in similar studies.
