Detoxification of aflatoxin in poultry feed by aqua-ammonia method.

摘要

This study was conducted to determine the effect of aqua-ammonia on aflatoxin detoxification of rice in poultry feed. Weighted amounts of aflatoxin contaminated powered rice were added to the broiler feeds to induce aflatoxin concentrations of 5, 15 and 40 and 5, and 10 and 35 mg/g in broiler starter (SM) and finisher (FM), respectively. Detoxification of aflatoxin was carried out using 1.5% aqueous ammonia solution. Three days after ammoniation, the aflatoxin content (35 mg/gm) of poultry feed was reduced to non-detectable level. Crude protein and moisture content increased but crude fat, acid insoluble ash, crude fibre and salt remained the same..
