制定了一个框架，以表征印度尼西亚、越南和泰国畜牧系统中的抗菌药物使用/抗菌药物耐药性复合体。农场盈利能力，疾病预防和死亡率降低被确定为驱动因素，对抗菌剂在畜牧系统中的使用。结果表明，抗菌剂的使用在所有研究部门都很高，常规预防性使用对肉鸡生产系统特别重要。误导性的饲料标签被认为是收集准确的抗菌剂使用数据的障碍，农民不知道一些商业饲料中含有的抗菌剂。经济分析发现，与其他农业投入相比，抗菌剂的成本较低，而且农场的盈利能力很难平衡。高发病率和低价格被认为是造成经济损失的潜在因素。研究表明，在小规模家禽生产系统中使用抗菌剂可以提高饲料转化率和整体生产率。然而，数据有限，无法充分量化这些潜在收益及其对粮食供应的影响。在研究期间，所有国家都接受并实施了关于更好地管理牲畜抗菌剂使用和监测抗菌剂耐药性的政策。未来的政策在该地区制定进一步的抗菌药物使用干预措施时需要考虑农场层面的经济和牲畜食品供应问题。
A framework was developed to characterize the antimicrobial use/antimicrobial resistance complex in livestock systems in Indonesia, Vietnam, and Thailand. Farm profitability, disease prevention, and mortality rate reduction were identified as drivers toward antimicrobial use in livestock systems. It revealed that antimicrobial use was high in all sectors studied, and that routine preventative use was of particular importance to broiler production systems. Misleading feed labeling was identified as a hurdle to the collection of accurate antimicrobial use data, with farmers being unaware of the antimicrobials contained in some commercial feed. Economic analysis found that the cost of antimicrobials was low relative to other farm inputs, and that farm profitability was precariously balanced. High disease and poor prices were identified as potential drivers toward economic loss. The research indicates that antimicrobial use in small-scale poultry production systems improves feed conversion ratios and overall productivity. However, data were limited to quantify adequately these potential gains and their impacts on the food supply. During the study, all countries embraced and implemented policies on better management of antimicrobial use in livestock and surveillance of antimicrobial resistance. Future policies need to consider farm-level economics and livestock food supply issues when developing further antimicrobial use interventions in the region.
