H₂S Control for Animal Housing Systems with Liquid Manure - Oil Sprinkling

Pro	Con
Easy, multiple approaches to application	Need to be careful not to create slippery surfaces
Variety of oil sources available	Repeated (daily) application needed

Coating surfaces to control emissions and dust has involved the use of vegetable oil, either sprayed or sprinkled in animal pens. Data from a Minnesota study showed that hydrogen sulfide reductions were 40 to 60 percent in the oil-sprinkled rooms, following a detailed protocol for oil application. There was a 40 to 70 percent reduction in odor, but no effect on ammonia concentration was observed. Oil sprinkling involves safety issues such as the slippery conditions of pens and alleys following repeated oil applications. Costs are minimal for the vegetable oil, and other costs involve a sprayer and labor for the daily oil application.
