The current prevalence of swine diseases in Guangdong and Countermeasures

At present, with conservation of the pig industry, the case of swine farms are becoming increasingly complex, old and sick and some farms are not extinguished, a new disease and hair; some farms some of the typical symptoms are under control, and SARS type symptoms, but still exist; some farms due to the feeding, nutrition and sanitation deficiencies often result in multiple causes of mixed infection of pigs, and so the causes of the complexity of swine to pig disease made it difficult to control, while increasing prevention costs, increase the cost of pig.

The current popular features swine
An old disease still exists. With our intensive, large-scale pig farming industry, swine increased distribution channels, resulting in epidemics of objective conditions. Some have led to control of infectious diseases, sexually transmitted diseases such as blisters, resurgence of classical swine fever, etc., was the proliferation trend.
Two new diseases continue to increase. In recent years, the rapid development of China's pig industry from domestic and foreign varieties and the introduction of the number of pigs increased. Due to lack of effective means of detection, resulting in as swine dysentery, pleuropneumoniae, porcine reproductive and respiratory syndrome, porcine proliferative enteritis and other diseases into our country at present, although only in some areas, but has great potential danger must pay close attention.
Three strains and the atypical variant disease. Some infectious pathogen in the process of mutation popular, some less virulent, with pigs in the immune level is not high or inconsistent, leading to some of the swine in the prevalence, symptoms and pathological changes in atypical changes, the occurrence of atypical infection and disease, the old disease with new faces appear, such as atypical swine fever. These diseases lead to misdiagnosis and immune failure, causing serious economic losses.
Four drug-resistant strains increased. Some farms in recent years due to long-term improper use of antibiotics and feed additives containing antibiotics, many bacterial resistance, often to make prevention and treatment failure.
Five bacterial and parasitic diseases in some of the hazards increase. With the increase in intensive pig farms and pig have been expanding, increasingly serious pollution, bacterial and parasitic diseases increased significantly. Diseases such as E. coli, Streptococcus suis, Mycoplasma disease and swine coccidia, small bag of worms, whip worms, scabies and other diseases. Many pig pathogen is widely present in the environment, through a variety of means of communication. These environmental microbial pathogens have become common in bacteria and pig farms of constant incidence.
More than six causes of mixed infections. Now pigs to infectious diseases, and more mixed for multi-pathogen infection. Such as porcine respiratory disease, usually pigs breathing disease, lung disease, swine infectious atrophic rhinitis and other mixed infections. This multi-pathogen co-infection, difficult to diagnose and control, required to distinguish between primary and secondary diagnosis, a comprehensive analysis of field and laboratory tests in order to make the correct diagnosis.
