“…NH3 concentrations in Turkish dairy barns varied 0.4 ppm to 9 ppm in a summer season (Simsek et al, 2012). Kilic and Yaslioglu (2014) reported lower values for NH3 concentrations in a laying hen house compared with this study results. Summer NH3 and CO2 concentrations ranged 7-11 ppm and 533-904 ppm, respectively in their study.…”

“…NH3 and CO2 concentration was measured in broiler houses (Atilgan et al, 2010;Simsek et al, 2013), dairy barns (Simsek et al, 2012) and laying hen houses (Kilic and Yaslioglu, 2014;Kocaman et al, 2006). According to Simsek et al (2013), average NH3 concentration in layer house was measured around 5 ppm in summer season.…”

: Indoor air quality in animal barns directly affect to animal productivity. Measuring the pollutants in animal barns proves the negative effects of gases on health of animals and workers. Most studies in this context focused on some pollutant gases such as ammonia, carbon dioxide, methane and hydrogen sulfide in dairy barn and poultry houses. Less attention in studies in scientific literature was paid to sheep barns which may have more important portion than other animals for the animal production sector of some countries. This paper revealed the concentrations of ammonia (NH3) and carbon dioxide (CO2) in naturally ventilated sheep barn in Bursa region, western Turkey. Also indoor environmental conditions such as temperature and relative humidity were measured simultaneously with pollutant gas concentrations. Regression and variance analyzes were applied to assess data collected in sheep barn whole over the study period. The average NH3 concentration during the study was 15 ppm for exhaust and 0.77 ppm for ambient, CO2 concentration was 1022 ppm for exhaust and 457 ppm for ambient. There was significant difference among measurement days for exhaust NH3 and CO2 concentrations (P< 0.001). The lowest NH3 concentration was 8 ppm while lowest CO2 concentration was 277 ppm, and the highest concentrations were 38 ppm for NH3 and 1700 ppm for CO2. Also minimum, maximum, average values for indoor temperature were 16.06°C, 26.53°C, 20.69°C, respectively, while minimum 43.42%, maximum 89.6%, average 71.23% values for relative humidity were obtained. According to regression analyze results, the exhaust NH3 concentration related statistically significant with air velocity. The standardized coefficients suggest that indoor temperature and relative humidity sustained the greater effects on CO2 concentrations (P< 0.001).

Hayvan barınaklarında kirleticilerin ölçümleri hayvan ve çalışan sağlığı üzerine olan olumsuz etkileri ortaya koymuştur. Bu amaçla yapılan birçok çalışmada, süt sığırı ahırları ile kanatlı kümeslerindeki amonyak, karbondioksit, metan ve hidrojen sülfit gibi kirleticiler üzerine yoğunlaşmıştır. Bilimsel literatürde, bazı ülkelerin en önemli hayvancılık sektörlerden birisi olan koyunculuk işletmelerine daha az yer verilmiştir. Bu çalışma, Bursa bölgesinde faaliyet gösteren doğal havalandırmalı koyun ağılında amonyak ve karbondioksit konsantrasyonlarına ilişkin ölçüm sonuçlarını göstermektedir. Ayrıca, sıcaklık ve bağıl nem gibi iç ortam çevre koşulları da kirletici gaz konsantrasyonları ile birlikte eş zamanlı olarak ölçülmüştür. Çalışma periyodu süresince koyun ağılında elde edilen verilerin değerlendirilmesi için varyans ve regresyon analizleri uygulanmıştır. Çalışma sonunda ortalama NH3 konsantrasyonu çıkış açıklığında 15 ppm ve giriş açıklığında 0.77...

“…The highest concentration of this gas is in the height of 50 cm, at the level of the birds, forming an undesirable microenvironment as a product of the microbial fermentation of excreta (Ferreira, 2010). When in concentrations higher than tolerable, ammonia causes primarily irritation of the mucous membranes of eyes and respiratory system in birds and later, after falling into the bloodstream, has a toxic effect over the physiological metabolism, leading to a decrease in ration consumption and reduced weight gain, therefore interfering in the wellbeing and health of the broilers (Kilic and Yaslioglu, 2014). Alencar et al (2002) proposed that tolerable exposure levels to workers are around 25 ppm for an 8 h working day, but for smaller workloads, it can be up to 35 ppm.…”

The Brazilian broiler industry is the most prominent branch in farming, due to its high levels of productivity. However, there is a growing concern about the environmental damages caused by such an activity, in special the atmospheric air pollution, as a consequence of the high volume of residues generated and the damages made to the environment. Air pollution, despite being most of the time detected by undesirable odoriferous substances, can be caused by numerous atmospheric pollutants such as particulate matter, odorless gases, non-volatile compounds, amongst others. This negatively impacts the health of both humans and animals, as well as of the surrounding ecosystem. Broiler production can be understood as a range of steps necessary to poultry meat production. Hence, their emissions can be computed all the way from the grain production, the feed fabrication, the poultry farming to, finally, the slaughtering and recycling of animal based products. As the poultry chain is well-segmented in its functions, it is necessary to establish and quantify the real impacts caused by its sectors and define mitigation controlling measures in regards to air pollutants.

“…The magnitude of NH 3 concentration in poultry facilities varies by housing systems (cage, on litter, alternative systems, or aviaries), bird density (in cage or on unit floor area), feed composition, house management, and ventilation management ( Kilic and Yaslioglu, 2014 ). High NH 3 concentrations in poultry houses can adversely affect the health and production performance of birds ( Charles and Payne, 1966a , Miles et al., 2004 , Miles et al., 2006b ) and can cause respiratory diseases (e.g., coughing, upper respiratory tract bleeding, excessive secretions, and lung bleeding or inflammation).…”

Air temperature, carbon dioxide, and ammonia assessment inside a commercial cage layer barn with manure-drying tunnels

Understanding the air temperature distribution, ammonia ( NH 3 ) and carbon dioxide ( CO 2 ) levels in poultry housing systems are crucial to poultry health, welfare, and productivity. In this study, 4 Intelligent Portable Monitoring Units and 7 temperature sensors were installed inside and between the cages and above 2 minimum ventilation fans of a commercial stacked-deck cage laying hen house in the Midwest United States (425,000 laying hens) to continuously monitor the interior environment over a 6-month period. During cold conditions (March 12th–May 22nd), there was a variation noted, with barn center temperatures consistently being highest in the longitudinal and lateral direction ( P < 0.001) and the top floor deck warmer than the bottom floor ( P < 0.05). During hotter conditions (May 23rd–July 26th), the interior thermal environment was more uniform than during the winter, resulting in a difference only in the longitudinal direction. The daily CO 2 and NH 3 concentrations were 400 to 4,981 ppm and 0 to 42.3 ppm among the 4 sampling locations, respectively. Both CO 2 and NH 3 decreased linearly with increasing outside temperatures. The mean NH 3 and CO 2 concentrations varied with sampling locations and with the outside temperatures ( P < 0.001). For CO 2 , the minimum ventilation sidewall had lower values than those measured in the barn’s center ( P < 0.05) during cold weather, while the barn center and the manure room sidewall consistently measured the highest concentrations during warmer weather ( P < 0.05). For NH 3 , the tunnel ventilation inlet end consistently had the lowest daily concentrations, whereas the in-cage and manure drying tunnel sidewall locations measured the highest concentrations ( P < 0.001). Higher NH 3 and CO 2 concentrations were recorded within the cage than in the cage aisle ( P < 0.05). The highest NH 3 concentration of 42 ppm was recorded above the minimum exhaust fan adjacent to the manure drying tunnel, which indicated that higher pressure (back pressure) in the manure drying tunnel allowed air leakage back into the production area through nonoperating sidewall fan shutters.
