A gutter system is disclosed for use in raising animals. The system includes a plurality of channels for carrying animal waste. Enclosures are mounted above the gutter system and a waste-permeable floor is provided to allow waste from the animals to pass into the channel. A gutter unit includes walls for supporting the floor which are chamfered to prevent accumulation of waste between the supporting walls and the floor. Sidewalls support the animal enclosure and have slots which open outwardly from the animal enclosure to allow waste outside of the enclosure to be swept through the slot into the gutter system. A method for forming the gutter system is disclosed and includes inversion casting of a material, such as concrete.
