不同养殖规模下生猪疫病风险认知对养猪户生物安全行为的影响——基于河北省786个养猪户的调查

为了解动物疫病风险认知对养殖户生物安全行为的影响,本研究以河北省786个生猪养殖户为调研对象,通过建立多元有序Logistic模型,研究了生猪疫病风险认知对养猪户生物安全行为的影响,并引入养殖规模作为解释变量,分析了不同规模养猪户生物安全行为和生猪疫病风险认知差异。结果表明:1)养猪户生猪疫病风险认知对其生物安全行为采纳有显著影响,其中外部环境风险认知影响最大,其次是生猪易感性风险认知和生猪病原的危险性风险认知;2)大、中、小和散户4种养殖规模对养猪户生物安全行为有显著影响,且不同养殖规模下其生物安全行为偏好有所差异;3)不同规模养猪户的生猪疫病风险认知有一定差异;4)养猪户生物安全行为受其个人特征、经营特征等多种因素影响。据此,本研究提出加强养猪户生猪疫病风险认知培训,分类施策促进不同规模养猪户生物安全行为建设,鼓励养猪户向规模化、标准化方向发展,培养新型养猪人等政策建议。

Effects of pig disease risk perception on biosafety behaviors of pig farmers with different breeding scales: Based on a survey of 786 pig farmers in Hebei Province

To understand the impact of the animal disease risk awareness on the biosafety behavior of farmers, based on the survey data of 786 pig farmers in Hebei Province, this study established a multivariate orderly Logistic model to study the impact of pig disease risk perception on the biosafety behavior of pig farmers. Breeding scale was introduced as the explanatory variable to analyze the difference in biosafety behavior of pig farmers with different scales. The results showed that: 1)The pig disease risk perception of pig farmers had a significant impact on their biosafety behavior adoption, among which the external environment risk perception had the largest impact, followed by the pig susceptibility risk perception and the risk perception of pig pathogens; 2)The four breeding scales of large, medium, small and retail investors had significant impact on the biosafety behavior of pig farmers, and the preference of biosafety behavior was different under different breeding scales; 3)There was a certain difference in the risk of hog disease among pig farmers of different scales; 4)The pig farmers'' biosafety behaviors were affected by their personal characteristics, business characteristics and other factors. In conclusion, this study proposed to strengthen the awareness training of pig epidemic risk, promote the construction of biosafety behavior of pig farmers of different scales, encourage pig farmers to develop in the direction of scale and standardization and cultivate new pig farmers.
