The use of antimicrobials in the pig sector in the Netherlands has been reduced by more than 70% over the last decade. However, there is still a considerable number of pig farms that have not been able to lower their antimicrobial usage (AMU) to a sufficiently low level, comparable to the majority of the other pig farms. Therefore, an intervention study was initiated to lower on-farm antimicrobial use in which 45 pig farms with high AMU were recruited. These farms were coached over a period of 2 years whereby different management interventions were introduced. During the 2-year study period a significant reduction of 13 and 17% in total AMU was seen in weaned piglets and fattening pigs respectively. The introduction of coaching as well as multiple management interventions were (univariably) associated with the decrease in AMU. After mutual adjustment of coaching and individual interventions, the association between coaching and AMU became substantially weaker, indicating that coaching and interventions were interrelated and specific interventions explained the reduction in AMU. In conclusion, a coaching effect was observed in this study, with an effect on AMU through specific interventions. More insights are needed regarding the role and effects of coaching on the influence on the management team comprising the farmer, veterinarian and (feed) advisor, and interventions implemented.
在过去十年中，荷兰养猪业的抗菌药物使用量减少了70%以上。然而，仍有相当数量的养猪场未能将其抗菌药物使用量（AMU）降至足够低的水平，与大多数其他养猪场相当。因此，启动了一项干预研究，以降低农场的抗菌药物使用量，招募了45个抗菌药物使用量高的养猪场。这些农场在两年的时间里接受指导，期间引入了不同的管理干预措施。在为期两年的研究期间，断奶仔猪和育肥猪的总抗菌药物使用量分别显著减少了13%和17%。引入指导以及多种管理干预措施（单变量）与抗菌药物使用量的减少有关。在对指导和个别干预措施进行相互调整后，指导与抗菌药物使用量之间的关联变得明显较弱，这表明指导和干预措施相互关联，特定的干预措施解释了抗菌药物使用量的减少。总之，本研究观察到了指导效果，通过特定干预措施对抗菌药物使用量产生了影响。关于指导对由农民、兽医和（饲料）顾问组成的管理团队的影响以及实施的干预措施的作用和效果，还需要更多的见解。
