A multimycotoxin screening report of about 33 pearl millet (Pennisetum glaucum) samples were prepared in the Animal Feed Analytical and Quality Assurance Laboratory, Namakkal during the months of August and September, 2023. The samples were received to the laboratory from the livestock and poultry farmers of different geographical regions of Tamil Nadu. Among the 33 pearl millet samples, the Aflatoxin B1 was the most predominant toxin, the concentration of Aflatoxin B1 and B2 were ranged widely from 11 to 1155 ppb and 8 to 116 ppb. The mean value of Aflatoxin B1 and B2 were observed to be 310 ppb and 33.71 ppb. The moisture percentage of the pearl millet samples were varied from 11.02% and 13.60%. The mean value of the moisture content was 12.07%. The samples with high AFTB1 and high moisture had an earthy odour also. About 57.58% of pearl millet samples were recorded above 100ppb of Aflatoxin B1. Conclusively, the mycotoxin contamination of the samples may be due to moistening and mold growth. The ingestion of Aflatoxin B1 contaminated sample with higher concentration by livestock and poultry may result in immunosuppression, reduction in egg production, poor weight gain and even mortality also. Hence, the farmers were advised to routinely analyze their feed ingredients like cereals and oilcakes for multi mycotoxin at the nearby feed analytical laboratory to avoid financial loss.
