How Does Epidemic Prevention Training for Pig Breeding Affect Cleaning and Disinfection Procedures Adoption? Evidence from Chinese Pig Farms

SIMPLE SUMMARY: An animal epidemic poses a severe threat to the economic development of a country. Pig farmers are crucial in controlling the spread of viral infections in pigs. As a crucial component of the biosecurity system, selecting proper cleaning and disinfection (C&D) procedures is a dynamic and long-term decision that requires a higher knowledge base among pig farmers. In this study, we collected data from 333 pig farmers in the Sichuan Province of China—a region significantly affected by the African swine fever (ASF) virus. The collected data were analyzed to elucidate the mechanism of the impact of epidemic prevention training on enhancing pig farmers’ adoption of C&D procedures. The empirical results showed that epidemic prevention training promotes the adoption of C&D procedures among pig farmers. In addition, biosecurity cognition plays a partially mediating role in epidemic prevention training, influencing the adoption of regular and comprehensive C&D procedures. ABSTRACT: African Swine Fever (ASF) is a highly infectious disease, severely affecting domestic pigs and wild boar. It has significantly contributed to economic losses within the pig farming industry. As a critical component of biosecurity measures, the selection of cleaning and disinfection (C&D) procedures is a dynamic and long-term decision that demands a deeper knowledge base among pig farmers. This study uses a binary logit model to explore the effect of epidemic prevention training on the adoption of C&D procedures among pig farmers with irregular and regular C&D procedures based on micro-survey data obtained from 333 pig farmers from Sichuan. The endogeneity issue was handled using propensity score matching, resulting in solid conclusions. In addition, the critical mediating impact of biosecurity cognition was investigated using a bootstrap analysis. The empirical study demonstrated that epidemic prevention training encourages pig farmers to adopt C&D procedures, with biosecurity cognition significantly mediating. Furthermore, epidemic prevention training was more likely to promote the adoption of C&D procedures among pig farmers with shorter breeding experiences and those having breeding insurance. Our study emphasized the importance of implementing epidemic prevention training to improving pig farmers’ biosecurity cognition and promoting the adoption of C&D procedures. The results included suggested references for preventing ASF and the next epidemic of animal diseases.
