ABSTRACT:
The invention provides an improved stall house for livestock or, in particular, pig breeding in which the excrements from the animals can be disposed under very sanitary conditions with great labor saving. The inventive stall house comprises an array of pens with the floor formed of slatted boards through which the excrements can freely fall down on to the sawdust bed below in an underfloor excrement-receiving vessel extending from one end to the other of the array of pens and a travelling shuffler capable of running in the excrement-receiving vessel back and forth from one end to the other over the sawdust bed with simultaneous shuffling of the sawdust bed to introduce fresh air thereinto in order to promote the aerobic fermentation of the excrements by the aerobic fermentation bacteria in the sawdust. Additionally, an air blowout pipeline may be provided at the bottom of the sawdust bed which serves to further promote the aerobic condition of the sawdust bed and also to control the evaporation of the water content in the excrements.
