“…Après une exposition prolongée des oiseaux à l'ammoniac, une très légère réduction de l'activité ciliaire est notée. Les équipes de Carlile (1984) et de Al-Mashhadani et Beck (1985 ont signalé ces lésions, parfois associées à une congestion pulmonaire ou à une perte des cils trachéeaux. Ces deux dernières lésions n'ont été qu'occasionnellement observées au cours de notre étude.…”

“…The production of CO 2 in the experiment carried out by Para et al (2003) decreased with increasing weight of broilers from the mean weight of 0.25 kg/bird always up to the final weight of 1.5-2.0 kg/bird; the initial value reaching 1.85 l/h/kg and the final one 1.23 l/h/kg. A great influence (P < 0.001) of chicken age on CO 2 emissions can be deduced from the data in Table 4. CO 2 is also a product (at several stages) of the aerobic breakdown of uric acid (Carlile, 1984). The enzymatic degradation of uric acid is supported by warmer temperatures (Coufal et al, 2006).…”

AbstrAct:The quantification of emissions of greenhouse gases from human activities is of prime importance for determining the importance of their effect on the environment. The aim of this study was to test a hypothesis that the interior concentration and emission of carbon dioxide in chicken housing is impacted by the age of animals and season of fattening period. Carbon dioxide (CO 2 ) concentrations and emissions were assessed over six fattening periods in total. The major part of CO 2 seemed to have its origin in bird respiration with assumed production of approx. 147 kg of CO 2 /h. CO 2 emission was most affected by chickens towards the end of the grow-out period (P < 0.001) taking dominance over the process of natural gas burning by heaters. The mean CO 2 emission from the chicken house ranged between 120 and 247 kg/h in the first quarter of periods and between 325 and 459 kg/h in the last ones. The heaters could be theoretically a possible source of approx. 39 kg each hour if they worked continuously. CO 2 emissions were considerably more affected by ventilation rate (P < 0.001) than by CO 2 concentration in the indoor air.

“…However in one of the houses, at one measuring point, the NH 3 level reached 26 ppm, a concentration which has been recorded to have adverse effects on the health of the birds and the workers (9,20,21,22).…”

Ensuring good environmental conditions of the poultry houses can be costly for the farmers, but without it losses due to poor bird health and performance due to poor air quality can be much more detrimental to net returns. The goal of this study was to investigate the variations in air quality in various areas inside the laying hen houses. Ten houses with laying hen conventional battery cages were measured for O 2 , H 2 S, CO, NH 3, temperature, relative humidity, CO 2 , airfl ow and luminance. The results of the physical measures showed that temperatures in the houses were between 15.31-25.6°C, the relative humidity 48.03-81.12%, while the luminance rarely exceeded 8 lux. As for the gasses, the values for NH 3 rarely exceeded 8 ppm, although at some measuring points it reached 26 ppm. O 2 was generally at 20.9 %, and the levels of CO 2 were very low. No presence of H 2 S and CO was detected. In this study it was concluded that the measurement of the air quality in a house can vary depending of the places this measures are taken. Multiple measurement points are important because they may make the staff aware of the problems connected to low ventilation and culmination of harmful gases. The air quality in different positions in the houses is of great importance not only for the animal welfare, but also for the safety of the staff.
