The role of biosecurity in controlling intensive pig herd health

In an organized pig herd, individual animal health care is becoming increasingly less important. In today's environment, char-acterized by a large concentration of animals in a relatively small area, this situation necessitates health care at the farm level. It is commonly known that biosecurity measures are important in pig farming, as they are designed to prevent diseases from entering the farm and to restrict the spread of infections within it. The presence of various breeding diseases of bacterial or viral origin leads to decreased production performance and demands additional efforts from the farm's employees, resulting in higher medication usage and, consequently, reduced economic profit for the farmer. A health protection program in well-organized farming should also include regular parasitological checks, as parasitic infections considerably impact animal health. Thus, parasitological diagnostics must be a part of the routine health monitoring of pigs. It is acknowledged that the willingness of farm personnel to adopt biosecurity measures is crucial for achieving a high level of protection against patho-gen introduction and spread. Implementing these measures requires an understanding of the pigs’ health status. One of the most common risk factors is the introduction of acquiring boars, gilts, or weaned piglets with unknown health status. Along-side the aforementioned measures, vaccination programs also play an important role in stabilizing the health of pigs. Pro-moting good health in organized herds involves applying a system of preventive measures.
