**Conference Overview**
Swine enteric diseases can cause significant economic losses to pig production. As the pig farming industry in China matures and competition intensifies, reducing production costs and improving efficiency, particularly by minimizing economic losses caused by enteric diseases, has become a growing concern.
One of the major swine enteric diseases is Porcine Ileitis, also known as Porcine Proliferative Enteropathy (PPE). It is a common contagious intestinal disease in pigs caused by infection with *Lawsonia intracellularis* (a Gram-negative bacterium). The disease is characterized by adenomatous hyperplasia of immature intestinal cells in the crypts of the ileum and colon. It can occur year-round but is most prevalent during hot and rainy seasons. The natural incubation period is 8-10 days, and it primarily affects pigs from weaning to adulthood, with growing-finishing pigs aged 6-16 weeks being the most susceptible. The disease leads to slow growth, reduced daily weight gain, poor feed conversion, decreased appetite, and pale skin in nursery and finishing pigs, resulting in substantial economic losses for the pig farming industry, especially in large-scale operations.
Porcine Ileitis has a high incidence rate and is widespread globally, with a history of over 70 years. The incidence rate ranges from 5% to 40%, and while the mortality rate is generally low (1%-10%), the growth rate of affected pigs is significantly reduced. If secondary infections occur, the mortality rate can rise to 40%-50%.
Proliferative enteropathy occurs worldwide, particularly in regions such as Europe and the Americas, and is also common in pig farms across Asian countries. In recent years, the incidence of this disease has been increasing in large-scale pig farms in China. Improving the overall health of pigs, enhancing the growth rate of nursery and finishing pigs, and increasing the survival rate throughout the production cycle have become critical focus areas for maintaining economic benefits and sustainable development in the industry. While preventing major diseases such as African Swine Fever, pig farmers are also paying increasing attention to diseases like Ileitis, which cause significant economic losses.
In China, awareness and research on this disease are still insufficient. The ability to clinically prevent, diagnose, and treat Ileitis remains relatively weak. As the scale of pig farming in China continues to expand, the threat posed by this disease to the industry will become increasingly severe.
The International Symposium on Swine Enteric Diseases will focus on Ileitis while also addressing other diseases, offering a two-and-a-half-day program of exchange and training.
The half-day pre-conference forum will cover topics such as Porcine Epidemic Diarrhea (PED), Porcine Rotavirus, *E. coli*, and *Salmonella*.
The two-day Ileitis session will invite domestic and international experts to engage in in-depth academic exchanges and discussions on the pathogen and epidemiology of the disease, pathogen-host interactions, diagnosis, prevention, clinical practices, and research advancements. Companies will also be invited to share their production prevention methods and experiences.
**Q: What is the purpose of this symposium?**
**A:** The purpose of this symposium is to:
1. Enhance the systematic understanding and prevention skills of pig farm staff regarding enteric diseases such as Ileitis.
2. Provide professional training for employees of standardized pig farming enterprises, improving their knowledge and practical abilities, thereby enhancing the economic benefits and competitiveness of the enterprises.
