This standard is a revision of the Thai Agricultural Standard (TAS) 6403–2022: Good Agricultural Practices for Pig Farms. It establishes the requirements for good agricultural practices in pig farming, covering farm components, farm management, personnel, animal health, animal welfare, environmental management, and record-keeping. These requirements aim to ensure that pigs produced by farms are suitable for further rearing or for consumption as food, while giving due consideration to food safety, animal health, animal welfare, and environment. This standard applies to farms raising pigs (scientific name: Sus scrofa), including both domesticated and wild subspecies.
