This is very similar to a broiler house used for rearing turkeys for meat. Variations in design include:
Closed house. The deep litter manure is removed at the end of the rotation, as for broiler. In special low emission systems the deep litter is removed from time to time (e. g. about nine times per rotation) and replaced with fresh litter.
House with open side walls. Especially for male animals; manure removal like in closed houses.
Partially ventilated littered floor. About 75% of the floor area is solid and 25% is a raised platform with a slatted floor covered with nylon cloth. Litter (wood shavings) is spread over both floor areas and air is blown through the slatted area to dry the manure. The system gives lower ammonia emissions than conventional systems.
