Filtration and mixing methods using zinc oxide nanoparticles were effective in controlling odour, ammonia and hydrogen sulphide emissions from swine facilities. This is important to the health and safety of the workers and the environment as well. The feasibility of these methods in commercial swine facilities was investigated. Applying the treatments had no effect on pig performance and manure nutrient characteristics. The mixing method was cost prohibitive at about 40.2% of the average total production cost while the filtration method was 2.8% of the average total cost of production. The filtration method is much more feasible to implement in a commercial barn.
