An improved livestock house includes a slanted floor, a funnel-shaped ditch coupled to a lower end of the slanted floor, a hole board installed at a connecting position of the slanted floor and the ditch, and a flush pipe installed at the front of the ditch. The slanted floor can make animals to excrete manure with their bottom facing downward involuntarily, and most of the animals manures together with urines are flushed into the ditch through the hole board and the manures entering into the ditch become smaller, and the smaller manures are collected by the urines or flushed by water in the flush pipe to a lower position of the ditch and then discharged to a wastewater treatment facility. The livestock house maintains a dry environment, improves problems of fermentations and bad smells, removes stinky wastewater, and maximizes the utility to achieve the economic, power-saving and environmental protection effects.
