| heal.abstract |
Aluminum sulfate (alum) has been demonstrated to reduce ventilation and heating requirements by lowering pH and thus reducing ammonia release from broiler litter during brooding of broiler chickens raised on used litter. It also has been shown to reduce darkling beetle populations, reduce runoff of phosphorus from fields where litter is applied, and increase nitrogen levels in treated litter. Currently, however, no economic benefit exists for reducing phosphorus runoff in Georgia, and as a result, the economic benefits are approximately equal to the additional costs of adding alum in winter flocks in North Georgia, and represent a net loss on summer flocks. This research demonstrated that much of the economic benefit of adding alum can be achieved by adding only half the recommended rate. Heating costs and bird performance were the same for full and half-rate applications. Soluble phosphorus and ammonium nitrogen levels were adversely affected by reducing alum application rates. While the environmental benefit of phosphorus runoff reduction would be lessened by adding less alum, an advantage may be realized industry wide if reduced rates are used since more growers would be likely to use it due to economic benefits. |
