“…For single-speed fans (endwall), their airflow was a function of static pressure, whereas for variable-speed fans the airflow was a function of static pressure and fan speed (revolution per minute or RPM). Runtime of each fan was monitored continuously using an inductive current switch (with analog output) attached to the power cord of each fan motor (Muhlbauer et al 2006). Each current switch's analog output was connected to the data acquisition system.…”

Expansion of the corn grain ethanol industry has led to increased availability of dried distillers grains with solubles (DDGS), and feeding DDGS to swine is becoming more common in pork production. Because feed is the primary cost in pork production and interest in air emissions from animal feeding operations is increasing, it is important to understand the impacts of non-traditional dietary formulations on aerial emissions. The purpose of this study was to identify and quantify the impacts of feeding DDGS on gaseous emissions from deep-pit swine finisher operations. To complete the study, two full-scale, commercial, colocated swine barns were monitored; one of the barns received a traditional diet, and the other received a diet that included DDGS. The constituents measured during this project were ammonia (NH3), hydrogen sulfide (H2S), and greenhouse gases (GHG) (carbon dioxide-CO2, nitrous oxide-N2O, and methane-CH4). At the time of this writing, results from this study indicated feeding 22% DDGS increased aerial NH3 emission from 3.1 g/pig-d to 4.6 g/pig-d and H2S emissions from 0.10 g/pig-d to 0.19 g/pig-d, but had no effect on GHG.

“…The cumulative ventilation rates from low to high stages accounted for 21%, 41%, 56%, 73%, 88%, 98% and 100% of the full ventilation capacity. Each stage of fans was temperature controlled and monitored with two current switches (Muhlbauer et al, 2006)). Static pressure sensors were mounted on the supporting beams near both sidewalls, with the high pressure terminal tubing extended to the outside of an exhaust fan.…”

Particulate matter (PM) in animal feeding operations is a concern for the occupants and the surrounding community. Baseline measurements of the concentration and emission rate of PM are the first step toward assessing the environmental impact of animal feeding operation and evaluating the effectiveness of dust control strategies. This study presents the results of the PM measurement at a high-rise layer house in central Iowa. The average PM10 emission rate over the 9-month measurement period was 21.6 (±10 S.D.) mg/bird/ day. Comparing with the emission rates reported literature, the mean and range of PM10 emission from highrise layer hen barns using cage systems were 33.5 and 19-48 mg/bird/day. The average PM2.5 emission rate over the measurement period was 2 (± 1.5 S.D.) mg/bird/day, which is less than literature values of 3.52-14.2 mg/bird/day.

“…Ventilation rate (VR) of the barn was derived by using in situ calibrated fan curves from a fan assessment numeration system (FANS) (Gates et al, 2004). After the actual airflow curves were established for all of the exhaust fans individually and in stage combinations, runtime of each fan was monitored and recorded continuously using an inductive current switch attached to the power supply cord of each fan motor (Muhlbauer et al, 2006). Analog output from each current switch was connected to the compact Fieldpoint modules.…”

Considerable progress has been made toward collection of baseline data on air emissions from U.S. animal feeding operations. However, limited data exist in the literature regarding turkey air emissions. The project described in this paper continuously monitors ammonia (NH 3) and particulate matter (PM) emissions from turkey production houses in Iowa (IA) and Minnesota (MN) for one year, with IA monitoring Hybrid tom turkeys and MN monitoring Hybrid hens. Mobile Air Emission Monitoring Units are used in the continuous monitoring. Data collection and analysis has been ongoing since May 2, 2007 for the IA site and October 9, 2007 for the MN site. Based on the one-year measurement at the IA site involving three flocks, daily NH 3 emissions (g/d-bird) from the IA turkey house varied from 0.04 to 6.4 (mean of 1.9) for flock 1 (May-Aug), 0.2 to 3.4 (mean of 1.3) for flock 2 (Aug-Dec), and 0.16 to 3.8 (mean 1.4) for flock 3 (Dec-Apr). The PM 10 emissions (g/d-bird) were 0.04 to 1.6 (mean of 0.58), 0.04 to 0.39 (mean of 0.2), and 0.04 to 0.82 (mean of 0.37) for flocks 1, 2, and 3, respectively; and the concomitant PM 2.5 emissions (g/d-bird) were 0 to 0.11 (mean of 0.048), 0 to 0.05 (mean of 0.021), and 0 to 0.14 (mean of 0.053) for flocks 1, 2, and 3, respectively. Annual mean emissions from the tom turkeys (including downtime emission), expressed as grams of constituent per bird marketed, were 169 g NH 3 , 40 g PM 10 , and 4.3 g PM 2.5 per bird marketed. Data collection and analysis at the MN site are ongoing.
