N2  - The present study focuses on using thin layer chromatography to detect estrogen residues in beef tissues of male and female calves. The samples from lean meat and fat were taken from each 10 male carcasses and also from each 10 female carcasses. The samples were collected from butchers shops and examined for detection of estrogen in lean meat and fat. The obtained results indicated that, estrogen residue was found in lean meat lesser than that recorded in flit ofthe same samples 6.2, 5.8, 5.3, 7.9 and 9.2 ng/g corresponding to 11.2, 12.3, 10.5,9.8 and 13.4 ng/g in fat respectively in female tissues. Otherwise, in male tissues it was 3.4, 2.7, 3.8, 1.36 and 4.2, in lean meat but in fat it was 4.6,5.7,5.2,6.15 and 4.9 ng./g, respectively
