What is the definition of biosafety in pig farms?

In recent years, the concept of biosafety system has been widely used in the field of biology, especially in farms and professional farmers (mainly pig and poultry farming). Large-scale pig farms are characterized by a large number of pigs, high feeding density, small range of activities and many stress factors, which provide favorable conditions for the occurrence and spread of epidemics. Once an epidemic occurs, its loss is much greater than that of ordinary free-range or small-scale pig farms.

According to the biological characteristics of pigs and the three basic links of infectious diseases (namely, the source of infection, transmission route and susceptible herd), the biosafety system of pig farms requires large-scale pig farms to establish a series of health care and productivity improvement measures for pigs in the production process.

This can also be regarded as the traditional comprehensive control, or the extension and development of veterinary health supervision under the condition of intensive production. By improving the layout of pig farms and the internal process design of pig houses, we can provide a good living environment for pigs, feed them with complete feed reasonably, and cooperate with scientific management to enhance their physique.

Epidemic prevention and health work needs to be regular and institutionalized. To carry out antibody detection and strengthen safety supervision, the whole production system and production process should meet the requirements of the bio-safety system of pig farms to ensure the safe production of standardized pig farms.
