1. Experimental intoxication induced in cockerels with varying doses o
f aflatoxin fed at the rate of 2.5 mu g, 5.0 mu g, and 10.0 mu g per g
of food resulted in appreciable changes in blood biochemical profiles
. 2. At all doses the aflatoxin caused decreases in serum total protei
ns, albumin: globulin ratio, serum total cholesterol, serum calcium an
d phosphorus and increases in serum globulins, alanine amino transfera
se (ALT) and aspartate amino transferase (AST) concentrations. 3. No c
hanges in serum bilirubin were observed. 4. Possible mechanisms for su
ch blood biochemical changes are discussed and related to liver cellul
ar damage caused by the aflatoxin toxicity.
