The invention relates to an animal accommodation with a manure pit adapted to reduce ammonia emission. In an embodiment the manure pit comprises for this purpose a layer of liquid, such as water, in which manure parts circulate until they reach a throughfeed in the manure pit. In an embodiment the animal accommodation comprises a floor grating with an open area of at least 30% so that manure drops easily through the floor grating. In an embodiment the floor grating is provided on an upper side with a rubber-like or rubber layer, whereby the floor grating can be cleaned by the livestock walking over it. The floor grating is preferably supported on the floor of the manure pit by means of support legs. The invention also relates to an improved manure separator.
