With the maturation of China's pig farming industry, the degree of intensification is increasing, and competition is becoming more intense. The breeding of high-quality pigs and the management of breeding populations have become key links in sustainable production, improving the efficiency and competitiveness of pig farms. The International Symposium on Pig Breeding (SRS) has been successfully held for five sessions since 2016. The conference gathers well-known domestic and foreign experts in pig breeding and reproduction to provide systematic training on pig breeding and reproduction theory and practical skills for employees of pig farming enterprises. The purpose is to improve the management level and production performance of pig breeding farms, consolidate and strengthen the knowledge and practical abilities of pig farm employees, and bring cutting-edge information and advanced scientific solutions to the industry. The conference focuses on high-quality theoretical knowledge and practical production solutions, and the teaching experts have rich production and clinical experience. Since its launch, SRS has been well received by the industry, providing rare opportunities for pig production personnel to learn and improve, including more than 20 online courses continuously provided to the industry during the epidemic.
