Illinois Odor and Nutrient Control Proving Center
Importance of
achieving the Practical Objectives
The livestock industry is one of the largest value-added portions of agriculture in Illinois and consumes approximately 80% of the corn and soybeans produced. The major limitations to maintaining the livestock industry is the odor and dust from, and the poor working environments within, the production facilities. Reducing odor and dust emissions and improving working conditions in livestock buildings is critical to the swine and grain production industries.
Odor control technologies are developed in the laboratory and are tested in small-scale studies with most of the interactive variables controlled. These tests do not give strong enough assurance that the technology will work well in operating swine facilities that may have numerous other factors that affect its performance. Also, the technology may have an effect on factors unrelated to odor such as animal performance and worker health. Therefore, it is very important that we operate an odor control proving program to test technologies and practices under realistic production conditions. The Illinois Odor and Nutrient Control Proving Center allows rapid evaluation of new technologies and practices on the emission of dust and odor from swine production facilities.
Objectives
Develop a program to test newly developed and commercial odor control technologies and practices in operating swine facilities. Products and practices that are proven to work in this program can then be recommended to swine producers with confidence.
 | Identify and modify swine facilities for comparative studies of odor control interventions |
| Test effects of oil sprinkling of floor and manure surfaces |
| Test effectiveness of dedusters |
| Wet scrubbers on fan exhausts |
| Integrated nutritional management practices |
Work Completed
and Findings
Oil sprinkling
Four replications of an oil sprinkling study on finishing pigs have been completed and a preliminary study was also done. Results from the first four replication of the oil sprinkling experiments showed an average dust mass reduction of around 60% with the oil sprinkling treatment. Figure 1 shows dust mass levels during replication #1 of the oil sprinkling study.

Dust spatial distributions were measured using a multipoint sampler. The comparison of dust spatial distributions between the control room and oil treatment are shown in Figure 2.

Dedusters
Two dedusters were installed in one room for determining internal dust removal effectiveness in a swine finishing building during cold weather operation (Figure 3). Results of the deduster study show an average dust mass reduction of 33% over the last five testing periods.
