Oxytetracycline are known as one of the antibiotics that are often used in handling mastitis cases in livestock. This study was a descriptive study to determine the presence or absence of oxytetracycline residues in the milk of Etawah crossbreed (PE) goats in Kalipuro Village, Banyuwangi. The milk samples in the collection were then tested for antibiotic residues using the bioassay screening method using the standard bacterium Bacillus cereus ATCC 11778. Research conducted on 26 milk samples taken randomly from PE were obtained negative results. This is indicated by the absence of inhibition zones around the well filled with milk samples. In contrast to positive oxytetracycline control with a concentration of 1 µg/ml which produces a zone of resistance of about 18 mm. It can be concluded that the samples of PE goat milk taken randomly in Kalipuro village, Banyuwangi were not contain antibiotic residues, especially oxytetracycline antibiotics.
