ABSTRACT

The present study was conducted between November 2018 and July 2019 to evaluate the effect of farming practices on control and prevention of antimicrobial residues in goat milk in Jabal Awliaa and Soba administrative units in Khartoum locality, Khartoum State, Sudan. Information was collected through a checklist and field visits. Eighty milk samples from lactating goats were collected from the study area. Ten herds from dairy goat farms were selected and 2 dairy goats from each herd were randomly sampled. In addition, 20 dairy goats from 10 backyard households were selected and sampled. The Disc Assay Method employing Bacillus subtilis as test organism on nutrient agar was used to detect the presence of antibiotics in milk samples. The results indicated that only 3 (30%) of farms were found to identify their animals. However, half of the farms 5 (50%) were accidentally found to mix milk from a treated goat with the bulk tank. A number of 8 (80.0%) of the farms had labor in charge of treating the animals, while only 2 (20.0%) had veterinary doctors. All the farms had never kept records of treated animals. The results also revealed that antibiotic residue in dairy farms showed that 7 (35%) samples were found positive for antibiotic residue in the left quarter and 6 (30%) were found positive for antibiotic residue in right quarters. Moreover, the backyard goat's milk samples tested for antibiotic residue showed that 6 (30%) were found positive for antibiotic residue in the left quarter while for right quarter a number of 7 (35%) were found positive for antibiotic residue.
