PURPOSE: A floor system for a livestock poultry farm is provided to settle the nerves of chicks when inserting the chicks into the farm, and to maintain the temperature and the humidity inside the farm during winter time. CONSTITUTION: A floor system for a livestock poultry farm includes a floor material(10), and band protrusions(12). The floor material is installed on the farm, and includes a decomposition enzyme maintaining the temperature and the humidity inside the farm during winter time, and preventing the generation of respiratory organ disorders caused by dust from a mat and bacteria. The band protrusions are attached to the upper and lower sides of the floor material for preventing the slipping of the mat and chicks. Fixing holes are formed on both ends of the floor material for preventing the slipping of the floor material inside the farm using a fixture.
