Research suggests that many sheep farmers continue to carry out traditional antibiotic use practices despite new 'good practice' recommendations. The aim of this study was to group farmers depending on their attitudes around antibiotic use and antibiotic resistance, and determine the behaviours that are associated with the farmers in these groups. In 2017, a flock health survey was sent to British sheep farmers. K-means cluster analysis was used to identify groups of farmers with similar attitudes towards antibiotic use and resistance. A multivariable logistic regression model was built to determine the associations between farmers' past behaviours and their antibiotic attitude group. There were 461 responses. Two groups of farmers were identified based on their antibiotic attitudes. Cluster 1 were defined as the "discordant" group who had positive views of using antibiotics prophylactically and negative views of reducing antibiotic use. Cluster 2 were defined as the "concordant" group who were positive about reducing antibiotic use and had negative views about using antibiotics prophylactically. Using antibiotics in all lambs (OR = 2.689, CI = 1.571, 4.603), using antibiotics in all ewes (OR = 3.388, CI = 1.318, 8.706), always trimming diseased feet over the past three years (OR = 2.487, CI = 1.459, 4.238), not using a computer to record information over the past three years (OR = 1.996, CI = 1.179, 3.381), not changing worming practices over the past three years (OR = 1.879, CI = 1.144, 3.087), and farmers' perceptions that their sheep flock did not make a financial loss in the past three years (OR = 2.088, CI = 1.079, 4.040) were significantly associated with belonging to the discordant group. Talking to their veterinarian about antibiotic use or the frequency of veterinary visits were not associated with antibiotic attitude group. These results suggest that farmers who had attitudes relating to antibiotic use that did not align with current recommendations carried out more traditional practices, which were strengthened by their positive perceptions of profitability.
研究表明,尽管有新的“良好实践”建议,但许多绵羊养殖户仍继续沿用传统的抗生素使用方法。本研究的目的是根据养殖户对抗生素使用和抗生素耐药性的态度对他们进行分组,并确定与这些组中的养殖户相关的行为。2017 年,向英国绵羊养殖户发送了一份羊群健康调查。使用 K-均值聚类分析来确定对抗生素使用和耐药性具有相似态度的养殖户群体。建立了多变量逻辑回归模型,以确定养殖户过去的行为与他们的抗生素态度群体之间的关联。共收到 461 份回复。根据他们对抗生素的态度,确定了两组养殖户。第 1 组被定义为“不一致”组,他们对预防性使用抗生素持积极态度,对减少抗生素使用持消极态度。第 2 组被定义为“一致”组,他们对减少抗生素使用持积极态度,对预防性使用抗生素持消极态度。在所有羔羊中使用抗生素(OR = 2.689,CI = 1.571,4.603),在所有母羊中使用抗生素(OR = 3.388,CI = 1.318,8.706),在过去三年中始终修剪患病的蹄子(OR = 2.487,CI = 1.459,4.238),在过去三年中不使用计算机记录信息(OR = 1.996,CI = 1.179,3.381),在过去三年中不改变驱虫习惯(OR = 1.879,CI = 1.144,3.087),以及养殖户认为他们的羊群在过去三年中没有亏损(OR = 2.088,CI = 1.079,4.040)与属于不一致组显著相关。与他们的兽医讨论抗生素使用或兽医就诊频率与抗生素态度群体无关。这些结果表明,与当前建议不一致的抗生素使用态度的养殖户实施了更传统的做法,而他们对盈利能力的积极看法则强化了这些做法。
