Effect of detoxified aflatoxin-contaminated rations on broiler chickens

ABSTRACT

The effect of aflatoxin contaminated rations with 1000 ppb AFB1, detoxified by dilution, ammoniation and reaction with formaldehyde on broilers was investigated. The dilution method to 50 ppb revealed anemia and hypoproteinemia, but there was significant decrease in leucocytes and in gamma globulins and an increase in beta globulin. This indicates that the dilution must be to less than 20 ppb or to the national permissible limits. On the other hand, detoxification with ammonia and formaldehyde eliminated completely the aflatoxin. This was indicated by the elimination of blood abnormalities and relieved hypoproteinemia. But, it is very important to get rid of chemical residues of ammonia and formaldehyde as well as aflatoxin residues
