“…It was from 5.76 ou E • (s • pig) -1 to 46.79 ou E • (s • pig) -1 and mean value equalled to 20.93 ou E • (s • pig) -1 ( Table 3). This value is similar to results of measurements conducted in commercial deep-litter piggeries by Rzeznik et al [19]. The mean odour emission factor for finishers was 16.93 ou E • (s • pig) -1 .…”

The aim of this study was to examine the impact of inside temperature and relative humidity, ventilation rate and gas concentrations (NH3, N2O, CO2) on odour emissions from deep-litter piggery. The studied facility had temperature-controlled mechanical ventilation. The measurements were conducted from March to June 2014. During the research, selected microclimate parameters, as well as number and mass of animals were monitored and air samples were collected (two samples of air in each series of measurements). Temperature and relative humidity were measured using Testo 435-4 multifunctional measuring instrument. To measurements of gas concentrations was used the photo-acoustic spectrometer Multi Gas Monitor Model 1312. The concentration of odours in the air samples was determined by dynamic olfactometry with the TO 8 olfactometer, according to PN-EN 13725:2007. The odour concentration ranged from 450 to 2004 ouE · m–3 (mean 1048 ouE · m–3) and the mean odour emission factor was from 5.76 to 46.79 ouE · (s · pig)−1 (mean 20.93 ouE· (s · pig)−1.The statistical analysis showed that the inside temperature explained most of the variability of the odour concentration and the relationship was described by equation: cod = 5634 – 197 Tinside (R2 = 0.82, p ≤ 0.05). For odour emission factor, two parameters: the inside temperature and ventilation rate, explained most of the variability, according to the equation: EFod = 108 + 1939 VR – 5.5 Tinside (R2 = 0.81, p ≤ 0.05).

“…Only Wi et al (2019) determined a much higher factor, comparable to the results of this work, amounting to 3.12-16.56 g•day -1 •pig -1 .The momentary ventilation rate was constant and it was 4.42 m -3 •s -1 . The odor concentration in the studied fattening house ranged from 755 to 11775 ou E •m -3 and was diversified (coefficient of variation 43.8%) Rzeźnik et al (2014),. during research carried out in production buildings on deep litter, observed odor concentration values ranging from 137 to 1247 ou E •m -3 .…”

Livestock production is the basis of global food production and it is a serious threat to the environment. Significant environmental pollutants are odors and ammonia (NH 3 ) emitted from livestock buildings. The aim of the study was to determine the concentration and emission factors of ammonia and odors, in the summer season, from a deep-litter fattening house. The research was carried out during summer in a mechanically ventilated fattening piggery located in the Greater Poland Voivodeship. Ammonia concentrations were measured using photoacoustic spectrometer Multi Gas Monitor Innova 1312, and odor concentrations were determined by dynamic olfactometry according to EN 13725:2003 using a TO 8 olfactometer. The NH 3 emission factors from the studied piggery, in summer, ranged from 8.53 to 21.71 g•day -1 •pig -1 , (mean value 12.54±4.89 g•day -1 •pig -1 ). Factors related to kg of body mass were from 0.11 to 0.23 g•day -1 •kg b.m. -1 (mean value 0.17±0.06 g•day -1 •kg b.m. -1 ). Odor concentrations in the studied piggery were from 755 to 11775 ouE•m -3 and they were diversified (coefficient of variation 43.8%). The mean value of the momentary odor emission factors was 179.5±78.7 ouE•s -1 •pig -1 . Factor related to kg of body mass was 2.27±1.71 ou E •s -1 •kg b.m. -1 . In Poland and many other countries, the litter systems of pigs housing are still very popular. Therefore, there is a need to monitor the pollutant emissions from such buildings to identify the factors influencing the amount of this emission. Another important issue is to verify whether the reduction techniques, giving a measurable effect in laboratory research, bring the same reduction effect in production buildings.
