Background and Aim: Animal antimicrobials must be studied to determine if they have the same types, norms of use, and resistance patterns as those used in humans. This study aimed to facilitate the analysis of data on the use of antimicrobials in veterinary medicine and to aid in developing a strategy to prevent the emergence of antimicrobial resistance (AMR) in humans and animals. Materials and Methods: Data were obtained through a survey of 101 veterinarians working in animal clinics and independent practice in five regencies of Yogyakarta province. Results: Both of the antibiotics, antiparasitic (78.6%) and, antiseptic and disinfectant (68.0%), and antifungal (31.1%) were the most frequently used types of antimicrobials, while antivirals were the least used (9.7%). The most often treated animals with antimicrobials are pets (37%), followed by large and small livestock (30%), poultry (15%), and exotic animals (14%). Of the respondents, 89% were aware of the factors contributing to AMR, but only 47% monitored developments and expanded their understanding of AMR. The most common antibiotic classes were penicillin (71), tetracyclines (50), sulfonamides (41), fluoroquinolones (31), and aminoglycosides (27). Conclusion: All antimicrobials used in the animal health sector are also used in human medicine, which requires special consideration. This cross-use of antibiotics was a crucial factor in determining the cause of the spread of AMR between humans and animals. Keywords: animal health, antimicrobial use, Yogyakarta.

Background and Aim: The utilization of cassava leaves and peels, ceara rubber leaves, sweet potato leaves, Chinese Albizia leaves, and lophatheri leaves from Bojonegoro Regency has led to the poisoning of livestock due to antinutritional factors. Nevertheless, the plants are known to have bioactive components and potential antioxidant and antibacterial activity if appropriately processed. This study aimed to determine the antinutritional compounds as well as the antioxidant and antibacterial potential of these plants responsible for livestock poisoning in the Bojonegoro Regency. Materials and Methods: Extraction was performed by the maceration method using 70% (v/v) ethanol solvent. The samples were analyzed qualitatively to determine the presence of tannins, alkaloids, oxalates, cardiac glycosides, and cyanogenic glycosides. The antioxidant activity was determined using the 1,1-diphenyl-2-picrylhydrazyl method, while the antimicrobial activity was assessed by different testing concentrations (125, 250, and 500 mg/mL) against Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli. Results: The ethanolic extract of the plants was found to contain antinutritional tannins, alkaloids, cardiac glycosides, and cyanogenic glycosides suspected of causing livestock poisoning. Despite the presence of these antinutrients, all extracts also had antioxidant and antibacterial potential. Cassava peels and sweet potato leaves had the highest antioxidant activity, whereas Chinese Albizia leaves had the most potent antibacterial activity. Conclusion: Cassava leaves and peels, ceara rubber leaves, sweet potato leaves, Chinese Albizia leaves, and lophatheri leaves obtained from Bojonegoro Regency and used as agricultural waste contain antinutritional factors but also possess potentially effective antioxidant and antimicrobial components.
