International ClassesA01K 031/04A01K 001/01 AbstractAtmospheric growing conditions in high-rise animal rearing facilities are proved by spraying liquid alum periodically over the manure collection area. Improved high rise animal rearing facilities provided with a liquid alum treatment delivery system for misting or spraying the liquid alum over the manure collection area to strip ammonia gas from the air and to apply a chemical coating on a surface of the accumulated manure which reduces or prevents ammonia volatilization. The liquid chemical treatment comprises an aqueous alum solution containing 1 to about 50% by weight alum, applied at a rate of about 50-250 g of Al2 (SO4)3. 14H2 O per kg of manure as it accumulates. The improved rearing facilities and methods control the atmospheric conditions in the animal rearing area at less than or equal to about 25 ppm ammonia throughout the growing cycle.Field of SearchWith droppings handlingHaving combined roost and droppings board With building sanitary device or system Building floor having waste collecting gutter or draining means With mechanical scraper or conveyor With sanitary or cleaning means With animal waste handling means Building heating or forced air ventilation With ventilation means With electrical system or device Drain-type floor with waste collection means Activated by presence of animal Underlying belt type Mounted above or within existing human commode WASTE TOILET OR RELATED DEVICE Reciprocating Overhead or ceiling mounted supply conduit Moving (non-ground traversing) distributing means WITH SELECTIVELY PRESET FLOW CUTOFF OR INITIATING MEANS WITH MEANS CAUSING INTERMITTENT INTERRUPTION OF SUPPLY TO DISTRIBUTOR MEANS (I.E., ON-OFF) | |
