International audience ; In the Mekong Delta of Vietnam, poultry farmers use high amounts of antimicrobials, but little is known about the drivers that influence this usage. We aimed to identify these drivers using a novel approach that combined participatory epidemiology (PE) and Q-sorting (a methodology that allows the analysis of the subjectivity of individuals facing a common phenomenon). A total of 26 semi-structured collective interviews were conducted with 125 farmers representative of the most common farming systems in the area (chickens, meat ducks, and mobile grazing ducks), as well as with 73 farmers' advisors [veterinarians, veterinary drug shop owners, and government veterinarians/commune animal health workers (CAHWs)] in five districts of Dong Thap province (Mekong Delta). Through these interviews, 46 statements related to the antimicrobials' perceived reliability, costs, and impact on flock health were created. These statements were then investigated on 54 individuals (28 farmers and 26 farmers' advisors) using Q-sorting interviews. Farmers generally indicated a higher propensity for antimicrobial usage (AMU) should their flocks encounter bacterial infections (75.0-78.6%) compared with viral infections (8.3-66.7%). The most trusted sources of advice to farmers were, in decreasing order: government veterinarian/CAHWs, their own knowledge/experience, veterinary drug shop owners, and sales persons from pharmaceutical and feed companies. The highest peak of AMU took place in the early phase of the production cycle. Farmers and their advisors showed considerable heterogeneity of attitudes with regards to AMU, with, respectively, four and three discourses representing their views on AMU. Overall, farmers regarded the cost of AMU cheaper than other disease management practices implemented on their farms. However, they also believed that even though these measures were more expensive, they would also lead to more effective disease prevention.

This study aims to explore the farmers' perceptions of FMD vaccination using a reflexive research method called Q methodology. A structured sample was composed including 46 farmers selected according to gender, farming experience, level of education and production type. Statements relevant to the farmers' perceptions of and attitudes towards FMD vaccination, related to confidence, logistics, costs and impacts of vaccination, were developed. Results were analysed by principal component analysis, using R version 3.1.2. Three distinct discourses ""Believe"", ""Confidence"", ""Challenge"", representing common perceptions among farmers and accounting for 57.3 % of the variance, were identified. Consensus points were found such as: the feeling of being more secure after FMD vaccination campaigns; the fact that farmers take vaccination decisions themselves without being influenced by other stakeholders; the opinion that FMD vaccination is cheaper than the costs of treating a sick animal; and that vaccines provided by governmental authorities are of good quality. Part of the studied population did not consider vaccination to be the first choice strategy in prevention. This raises the question of how to improve the active participation of famers in the FMD vaccine strategy. Regular awareness raising is an important tool to foster active participation and to maintain the farmers' motivation to vaccinate.

This study aims to explore the farmers' perceptions of foot-and-mouth disease (FMD) vaccination using a reflexive research method called Q methodology. A structured sample was composed of 46 farmers selected according to gender, farming experience, level of education, and production type. Statements relevant to the farmers' perceptions of and attitudes toward FMD vaccination, related to confidence, logistics, costs, and impacts of vaccination were developed. Results were analyzed by principal component analysis and factor analysis. The influence of demographics and characterized variables on the respondent's contribution to each factor was also tested. Regarding the different beliefs and behavior toward FMD vaccination, the common perceptions held by Vietnamese cattle and pig farmers were divided into three discourses named Confidence (24 subjects), Belief (12 subjects), and Challenge (6 subjects). The identified discourses represented 57.3% of the variances. Consensus points were found, such as the feeling of being more secure after FMD vaccination campaigns; the fact that farmers take vaccination decisions themselves without being influenced by other stakeholders; the opinion that FMD vaccination is cheaper than the costs of treating a sick animal; and that vaccines provided by governmental authorities are of high quality. Part of the studied population did not consider vaccination to be the first choice strategy in prevention. This raises the question of how to improve the active participation of farmers in the FMD vaccine strategy. Taking into consideration farmers' perceptions can help to implement feasible vaccination strategies at the local level.

Purpose Since 2006, Vietnam has implemented mass vaccination against foot and mouth disease (FMD) for all cattle and buffaloes within specific targeted areas. However this strategy is still facing many logistical and economic constraints. This study aimed to explore South-Vietnamese farmers' subjectivities regarding FMD vaccination using a reflexive research method called Q methodology. This method allowed us to identify groups of farmers who shared similar viewpoints. Methods A structured sample of 46 farmers in Tay Ninh province was chosen. These 46 respondents were distinguished in socio - economic variables such as gender, experience level, education level and production's type. Statements relevant to farmers' attitude and perception toward FMD vaccination have been developed from previous groups and individual interviews, to produce a Q-set of 46 items. They covered 4 themes regarding vaccination: confidence, logistic, cost and impacts. Q method results were analyzed performing principal component analysis (PCA) using R version 3.1.2. Results Three factors, representing common perceptions between farmers and accounting together for 57,3 % of the variance were selected. Several consensus points were found across the factors: they feeling more secure after vaccination campaign; they strongly thinking that a good vaccination practice will make their animal have a good protection; they taking vaccination decision themselves without influenced from other actors; vaccination is cheaper than treatment cost; vaccines given by governmental authorities are of good quality. However there were several points of disagreement between factors: for some farmers (factor 3) if the housing and feeding conditions are good, they don't need to vaccinate their animals every year; the preferred type of vaccine (individually or multi dose) will depend between factors. Conclusions These outputs provided critical elements on the acceptability of FMD vaccination programs by farmers in Vietnam and allowed some recommendations on how to improve their involvement. Further researches are still required to understand and combine viewpoints of other actors involved in the vaccination campaign. (Texte intégral)
