Abstract

Oxytetracycline antibiotics 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 antibiotic residues in the milk of Etawa crossbreed goats in Kalipuro Village, Kalipuro District, 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 Etawa breeds dairy cattle 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 1μg / ml which produces a zone of resistance of about 18 mm. Based on observations of the inhibition zone, it can be concluded that the samples of Etawa crossbreed goat milk taken randomly in Kalipuro village, Kalipuro sub-district, Banyuwangi did not contain antibiotic residues, especially oxytetracycline antibiotics.
