The AgiliTRAC concept is a flexible and modular building capable of responding to all production systems in pig farming, with rapid and simplified implementation. Our building is composed of prefabricated concrete parts which come together to form a module constituting the base of the building. This module can be repeated as often as necessary in order to size the building according to the number of places desired. In order to be respectful of the environment and animal welfare, this building was designed to accommodate the TRAC'R phase separation solution. The AgiliTRAC concept adapts to all types of ventilation, elevations and frames. Faced with an expansion or an improvement in the prolificacy of the breeding, it will not be necessary for the breeder to reorganize his entire operation. It will be possible for him to expand each room with one or more modules without affecting the forward of the progress and biosecurity rules of his site. A multitude of possibilities are available to the breeder to build the most suitable building for his breeding.
