Understanding antibiotic use for pig farming in Thailand: a qualitative study

BackgroundAntimicrobial resistance (AMR), recognised as a serious and growing threat to global health, is promoted by multiple drivers, including antibiotic use in the livestock sector. Thus, understanding factors influencing antibiotic use in livestock production is essential to the design and implementation of effective interventions to reduce AMR. This qualitative study aimed to explore the experiences and views of the key actors associated with the use of antibiotics for pig farming in Thailand, from local farmers to officers in central government institutions. MethodsA total of 31 in-depth interviews were conducted with different categories of actors: pig farmers (n=13), drug retailers (n=5), veterinarians (n=7), government officers (n=3) and representatives of animal and human health associations (n=2). Themes emerging from the interviews were identified and explored using thematic analysis. In addition, direct observations were conducted in the pig farms. ResultsThe findings highlight the multi-faceted nature of the views and practices that may contribute to misuse or overuse of antibiotics in the study locations, including misconceptions about the nature of antibiotics and AMR (particularly among smallholders), lack of facilities and financial means to establish an antibiotic-free farm, lack of sufficient training on AMR and antibiotic prescribing for veterinarians, the profit motive of pharmaceutical companies and their ties to farm consultants, and lack of sufficient regulatory oversight. ConclusionsOur study indicates a clear need to improve antibiotic use for pig production in Thailand. Farmers need better access to veterinary services and reliable information about animal health needs and antibiotics. Innovative investments in biosecurity could improve farm management and decrease reliance on antibiotics, although the cost of these interventions should be low to ensure wide uptake in the livestock sector. Lastly, further development of professional training and clinical guidelines, and the establishment of a code of conduct, would help improve antibiotic dispensing practices.

Automated summary

The study reveals various factors contributing to antibiotic misuse or overuse in pig farming in Thailand, such as misconceptions about antibiotics, lack of resources for antibiotic-free farms, insufficient training for veterinarians, profit motives of pharmaceutical companies, and inadequate regulatory oversight. Improving access to veterinary services, providing reliable information on animal health and antibiotics, investing in biosecurity measures, and enhancing professional training and guidelines could help address the issue of antibiotic use in pig production in Thailand.
