Abstract:

Mycoplasmal pneumonia of swine (MPS) was caused by Mycoplasma hyopneumoniae (M. hyo), one of the most important causes of disease associated loss in swine production worldwide, affecting pigs of all ages and all types of farm or production systems. Once infection was established, it was very difficulty to eradicate. Many developed countries, particularly in Western Europe and North America, through eradicate the pathogeny to control the disease. But it was important to remember that each farm was unique and that the extrapolation the results from eradication programmes implemented within other herds may not necessarily apply. Because of less cost, simple application, highly successful and flexible, the “Swiss method” had been extensive used in many farms. This paper gave a review to some mainly successful “Swiss method” programs for eradicating the MPS in different farms worldwide and summarized them for domestic eradicating the MPS.
