A total of 30 maize samples, 30 deoiled rice bran (DORB), 20 groundnut oil cake (expeller) and 20 dried distillers grain soluble (DDGs) feeds samples were collected from different parts of Namakkal district. Aflatoxin B1 was estimated in all the samples by extracting the aflatoxin and spotted in an activated thin layer chromatography (TLC) plate method. Among 30 samples of maize, analyzed for Aflatoxins, 20 samples (60%) contained traces of aflatoxin B1 and 8 samples (26.6%) contained between 10-30 ppb. Two samples (6.66%) contained between 400-500 ppb. Similarly, among 30 samples of DORB analyzed for aflatoxins, 24 samples (80%) contained traces of aflatoxin B1 and five samples (16.6%) contained between 10-30 ppb. One sample contained between 50-100 ppb of aflatoxin. Three samples of GNC and Four samples of DDGS had 50-100 ppb of aflatoxin. It reveals that, very few samples of maize and DORB contained high level of aflatoxin. Hence the regular screening of toxins in every lot of feed prior to feeding the animals or poultry needs to be regularized.
