Popis: Male Fischer rats, 12 wk old, were fed 12 mg/kg aflatoxins in the diet. Severe reduction in feed intake and rapid weight loss were observed; mortality was 75–100% within 2 wk. Prepubertal males fed the same diet for 5 wk maintained pretreatment feed intake levels and gained considerable weight; survival was 100%. When the aflatoxin diet was fed to 7- and 9-wk-old males, mortality decreased. Castration afforded a 100% sparing effect from mortalities when performed before 10 wk of age, but had no beneficial action after this time. Testosterone administration resulted in 100% mortality in aflatoxin-fed castrates whereas no fatalities occurred in castrates fed aflatoxin only.
