Perception of Scale and Risk of Livestock Rearing and Its Impact on Perception of Epidemic Prevention Arrangement of Broiler Farms: Based on Survey of 331 Broiler Farm Households

Major animal epidemics have been impeding development of the livestock and poultry industries in China. Rational arrangement of epidemic prevention of animal farms ensures biosafety in construction of functional zone and construction of ancillary service. It is worth discussing whether scaled livestock farms' and farm households' cognition of the risk of animal epidemics would promote rational arrangement of epidemic prevention of the farms. The six mandatory requirements specified in the "Procedure for Inspecting Animal Epidemic Prevention Conditions" for arrangement of epidemic prevention were cited as framework for analysis of the data collected during the survey of a total of 331 broiler farms in six provinces. First of all, poisson regression was performed to determine factors affecting the number of requirements for farmers to lay out epidemic prevention arrangement, and then Probit model was applied to analyze factors affecting farmers' behaviors of overall epidemic prevention arrangement. Results show that increasing of the scale of farms may significantly increase the number of requirements and overall epidemic prevention arrangement. And depth of the cognition of animal epidemic risks is significantly and positively related to the number of requirements for epidemics prevention arrangement, but not much related to the overall epidemics prevention arrangement. Compared with the cognition of the risks, scale of the farms could affect more the standard epidemics prevention arrangement.
