Aflatoxin susceptibility of selected and control Japanese quail lines

1. The influence of aflatoxin on growth and mortality of diverse lines of quail was studied in five trials. 2. Feeding 5 or 10 micrograms aflatoxin/g diet from 4 to 7 weeks of age resulted in significant decreases in body-weight gain in all lines. 3. Similar gains for all treatments during the third week of feeding indicated that body weights were reduced only during the first two weeks. 4. Crop intubation with 4 or 8 mg aflatoxin/kg body weight resulted in different mortality patterns for the selected and control quail lines.
