Biosecurity 1 . National Level; Animal Quarantine Service 2. Local (Prefectural) Level; ・ Local Animal Health Station Network ・ Swift and Accurate Diagnosis 3 . Farm Level; National Standard of Livestock Rearing must be met first. Then Biosecurity chains should be tightened rigidly ・ Pigs ・ Semen introduction ・ Pig transportation ・ Human ・ Supplies ・ Dead pigs disposal ・ Feed ・ Water ・ Manure ・ Vermin and Insects ・ Air

Biosecurity Chain Biosecurity Chain: As strong as the weakest link

Veterinary Services Swift and Accurate Diagnosis is the key 1. National Level; For TADs ・ National Institute for Animal Health 2. Local (Prefectural) Level; For reportable diseases ・ Local Animal Health Station Network 3. Private Level; For other diseases ・ Local Animal Health Station ・ Univercity and private diagnostic lab Effective Veterinary Services to Swine Farms ・ Routine herd visits by veterinary consultants not only for health control but also for advice such as pig flow, biosecurity, housing and nutrition

Environment Control 1. No Pollution and Sustainability ・ Effective treatment of feces and urine ・ Cooperation with crop farms ２． Composting of feces ３． Water treatment of Urine ４． Feed management ・ Digestive amino acids formulation ・ Pellet and other heat treatments of feed ・ Mineral, Enzyme ・ Probiotics

Mother to Pig Infection Control ・ Complex diseases can not be easily controlled ・ Successful mother to pig infection control simplifies the health situation on farms ・ Production of healthy weaned pigs is the center of good pig production and mainly influenced by mother to pig infection control ・ The most relevant examples are PRRS and Mycoplasma hyopneumoniae

Mother to Pig Infection Control 1. Herd Immunity Stabilization ・ Health status of replacement gilts ・ Vaccination and Acclimatization ・ Age at introduction and recovering time 2. Assuring Colostrum Intake 3. Weaning age ・ Maternal antibody decay ・ Infection rate at weaning 4. Pig Flow ・ Isolated weaning and AIAO 5. AMU for lactating sows and pigs

Genetics and Nutrition 1. Rapid Genetic Improvement ・ Reproductive, growth and carcass performance ・ Disease resistant; marker assisted selection exists and gene editing is a new hope

Genetics and Nutrition 1. Rapid Genetic Improvement ・ Reproductive, growth and carcass performance ・ Disease resistant; marker assisted selection exists and gene editing is a new hope 2. Nutrition to match genetics ・ to meet amino acids requirements ・ to meet local pork market needs ・ to use local feed ingredients

AMU & AMR 1. Reduction of AMU to reduce AMR ・ One Health approach ・ AMR action plan ・ Survey of AMU 2. Research Effort ・ Factors affecting AMU ・ Relation between Biosecurity and AMU 3. Benchmarking ・ Ranking individual farm’s AMU level ・ Showing the way of reduction

Summary Excellent pig flow, biosecurity and veterinary services are essential for good swine production and advancement in swine farming. Also good balance of other factors such as environment control, mother to pig infection control, nutrition and genetics, AMU and AMR action, and others enhance the advancement in swine farming.
