This study examined the relationships between the attitudes and the management behaviour of the farmer and the on-farm welfare of their ewes. To our knowledge, this is the first study investigating these relationships in extensive sheep farming systems. Thirty-two sheep farmers and 6200 ewes were sampled across Victoria, Australia. Questionnaire interviews and on-farm animal welfare assessments were conducted. The ewes were assessed at two-time points, mid-pregnancy and weaning. To examine relationships between farmer and ewe variables, categorical principal component analyses, correlations and logistic regressions were used. The main findings of this study indicate relationships between farmer attitudes and management behaviour, consistent with findings from other more intensive livestock industries. Farmers were more likely to check the body condition of their ewes (Odds ratio = 2.37, P = 0.03), perform ultrasound pregnancy diagnosis (Odds ratio = 1.16, P = 0.02) and test for egg count before deworming sheep (Odds ratio = 2.88, P = 0.01) if they perceived these activities were important/valuable. In addition, farmers that performed these activities had a more active management style, and ewes in better welfare: fewer lame ewes at mid-pregnancy (r = -0.38 P = 0.04), and fewer ewes in need of further care at mid-pregnancy and weaning respectively (r = -0.47, P = 0.01; r = -0.50, P = 0.01). When combining the qualitative and quantitative analyses, behavioural attitudes (attitudes towards specific management behaviours) and perceived behavioural control (perceived barriers to performing the behaviour) emerged as the two main drivers underpinning farmer management behaviour. The results of this study indicate that the way farmers manage their ewes influences welfare outcomes, and management decisions are influenced by attitudes towards management practices. These findings demonstrate the opportunity to create change in farmer management behaviour and improve sheep welfare via targeted education programs.
本研究考察了农民的态度和管理行为与他们的母羊农场福利之间的关系。据我们所知,这是首次在广泛的绵羊养殖系统中调查这些关系的研究。在澳大利亚维多利亚州,对 32 名绵羊农民和 6200 只母羊进行了抽样调查。进行了问卷调查和农场动物福利评估。在妊娠中期和断奶时对母羊进行了两次评估。为了检验农民和母羊变量之间的关系,使用了分类主成分分析、相关性和逻辑回归。本研究的主要发现表明,农民的态度和管理行为之间存在关系,这与其他更密集的畜牧业的发现一致。如果农民认为这些活动重要/有价值,他们更有可能检查母羊的身体状况(优势比=2.37,P=0.03)、进行超声妊娠诊断(优势比=1.16,P=0.02)和在给羊驱虫前检查虫卵计数(优势比=2.88,P=0.01)。此外,进行这些活动的农民有更积极的管理风格,母羊的福利更好:妊娠中期跛行母羊较少(r=-0.38,P=0.04),妊娠中期和断奶时分别需要进一步护理的母羊较少(r=-0.47,P=0.01;r=-0.50,P=0.01)。当结合定性和定量分析时,行为态度(对特定管理行为的态度)和感知行为控制(执行行为的感知障碍)成为支持农民管理行为的两个主要驱动因素。本研究的结果表明,农民管理母羊的方式影响福利结果,管理决策受到对管理实践的态度的影响。这些发现表明,通过有针对性的教育计划,有机会改变农民的管理行为并改善绵羊福利。
