“…Results are in agreement with previous studies (Seedorf et al, 1998;Calvet et al, 2011) who reported that the ventilation rates increased with bird age and ranged between 1.8 and 4.9 m 3 h À1 bird À1 in winter. However, the ventilation rates in broiler house H3 were higher than broiler houses H1 and H2 (Table 1).…”

“…Results of this study follow the same trend reported for Mediterranean conditions, by Guiziou and B eline (2005) and Calvet et al (2011) who found a great increase in NH 3 emissions on day 28 during winter. Excluding differences between management practices, the higher NH 3 emission rates obtained in the present study to those reported by Calvet et al (2011) could be related with environmental factors and diets such as the high ventilation rate observed in the referred study (4.9 m 3 h À1 bird À1 in Spain against 3.4 m 3 h À1 bird À1 in Portugal).…”

“…Previous studies reported (Calvet et al, 2011;Brou cek and Cerm ak, 2015;Eugene et al, 2015) a great variation on gas emission rates between seasons and countries, being related with outdoor climate, housing and diet supplied to broilers. Hence, more studies are needed, mainly in warmer regions because a very limited number of studies have been conducted under these conditions.…”

a b s t r a c tBroiler husbandry is a significant source of ammonia (NH 3 ), nitrous oxide (N 2 O), carbon dioxide (CO 2 ) and methane (CH 4 ) emissions but scarce studies have been made under Mediterranean conditions. The aim of this study was to evaluate the NH 3 , N 2 O, CO 2 and CH 4 emissions on commercial broiler houses under Portuguese winter conditions. The study was made on a commercial broiler farm located in central Portugal. Three tunnel ventilated broiler houses with similar equipment and production practices were selected. The outdoor and indoor environmental conditions, gas concentrations and ventilation rates of each broiler house were measured during 42 days of growing cycle. Results showed that the maximum concentrations of NH 3 , N 2 O, CO 2 and CH 4 did not exceed the threshold values recommended to maintain indoor air quality on broiler houses. The average emission rates from broiler houses under winter conditions were 0.13 ± 0.04, 0.041 ± 0.002, 96.2 ± 8.8 and 0.226 ± 0.013 g day À1 bird À1 (22.0 ± 7.3, 6.7 ± 0.3, 16,028 ± 1465 and 37.7 ± 2.1 g day À1 LU À1) for NH 3 , N 2 O, CO 2 and CH 4 , respectively. Furthermore, NH 3 and N 2 O emission rates of this study are in the same range than measurements from most European countries, but CH 4 emission rate seems higher to those reported for Mediterranean countries.

Meeting hygrothermal and air quality requirements in livestock dwellings is crucial for upholding production quality standards. However, ventilation and air-conditioning in such enclosures is very energy-intensive, especially amidst climate change and intensifying summer conditions. This is due to large surface areas, livestock densities, and contaminants' generation rates. Hence, striving for more efficient passive cooling techniques is always a desired goal to reduce the anthropogenic emissions of the agricultural sector without compromising production quality. In this study, the energy savings' potential of two passive systems in a poultry house located in the semiarid climate of Beqaa Valley, Lebanon, was compared. The first system is the conventional stand-alone direct evaporative cooler (DEC), which evaporatively cools the outdoor clean air to temperatures close to its wet bulb. The second system combines with the DEC, an earth-to-air heat exchanger (EAHE) that sensibly

Particulate and gaseous emissions from intensive poultry facilities are major public and environmental health concern. The present study was aimed at exploratory monitoring of particulate matter (PM) and gaseous concentrations in controlled-environment facilities using low-cost sensors in Lahore, Pakistan. The indoors and outdoors of 18 broiler houses, grouped into three categories based on the age of birds: group I (1-20 days), group II (21-30 days) group III (31-40 days) were examined. Low-cost sensors Dylos 1700 and Aeroquals 500 series with different gas sensor heads were used to monitor PM and different gases such as nitrogen dioxide (NO2), hydrogen sulphide (H2S), carbon dioxide (CO2) and methane (CH4) respectively. Overall, the mean PM and gaseous concentrations increased with the age and activity of birds as compared with the non-activity time of birds. Statistically significant differences were observed in all measured parameters among the groups. The negative correlation between indoor and outdoor environments for PM and gas concentrations at some broiler houses demonstrates the contribution of additional sources to emissions in outdoor environments. The findings contribute to our knowledge of temporal characteristics of particulate and gaseous concentrations from poultry facilities particularly in Pakistan and generally to the capability of using low-cost sensors to evaluate emissions from such facilities.
