| Summary |
Two trials involving 60 chickens (40 days old) and 180 ducklings (l day old) were conducted to evaluate acceptance and utilization of aflatoxin contaminated ammoniated corn over 5-6 weeks feeding period. The corns artificially contaminated with aflatoxins
(120 µg/kg), after treated with gaseous ammonia, revealed non-detectable aflatoxin as determined by high pressure liquid chromatography.
The body weight gains of the poultry fed with aflatoxin contaminated ammoniated corn and supplement mixtures were heavier than those of poultry fed with normal non-ammoniated corn and supplement mixtures. According to the results of clinical signs, hematology, blood chemistry and histopathology studies, it was found that the poultry fed with aflatoxin contaminated ammoniated corn and supplement mixtures would not induce and abnormal reaction except the SGOT activities increased moderately and kid-ney weight/body weight ratio decreased over the 3 to 5 weeks feednig period in duckli-ngs. There was no influence on the body weight of the ducklings fed with contaminated corn and supplement mixtures in the test period, but the ducklings showed subclinical toxic reaction.
It is apparent that the ammoniation process improve the quality of aflatoxin conta-minated corns and the treated corns is suitable fattening poultry.
