Poultry production system in Thailand*
Poultry production | Biosecurity | Market orientation | Example |
---|---|---|---|
Sector 1 | High | Commercial | Industrial integrated system: all components of the production chain (e.g., hatchery, feedmill, poultry farm, slaughterhouse, processing plant, transportation) owned by company with strictly implemented procedures for biosecurity |
Sector 2 | Moderate to high | Commercial | Semivertical integrated system (or contract farming system): poultry houses owned by the farmer but chicks, feed, and veterinary service supplied by private company. Birds kept indoors with basic physical barriers and hygiene to prevent contact with other animals |
Sector 3 | Low | Commercial, local, or live-bird market | Layer farm with caged birds in open sheds or free-roaming birds that spend time outside the shed |
Sector 4 | None | Local | Village or backyard poultry: birds freely roam the village around people and other animals, including cockfighting |
