Experimental Aflatoxicosis in Young Japanese Quail ,

open access: yesPoultry Science, 1982
Japanese quail from the university colony fed graded levels of dietary aflatoxin (0, 1.25, 2.5, 5.0, 10.0, and 20.0 micrograms/g) from hatching to 4 weeks of age were comparatively resistant to aflatoxin as growth inhibition occurred at a dose of 5.0 micrograms/g or more as about 50% mortality occurred at a dose of 20 micrograms/g.
