“…Also, AT not only influence hen comfort and performance, but also affect other environmental conditions, such as ammonia and dust levels in poultry houses (Carlile, 1984). However, recommended AT and RH values for houses should be 15-20 o C and 60-70% (Kocaman et al, 2005). In this context, AT and RH of air are two major environmental factors controlling the heat stress of livestock.…”

“…As the chickens spend their life in poultry houses, in order to be able to perform their production capacities entirely, they should be kept in good environmental conditions with a good care as well as genetic characteristics. Chickens and their wastes generate different forms of air pollution, including ammonia, carbon dioxide, methane, hydrogen sulfide and nitrous oxide gases, as well as dust (Kocaman et al, 2005). Furthermore, broiler breeder needs good environmental conditions to increased rate of egg production, which is of great importance to the poultry industry particularly the broiler breeder sector.…”

In this field observational study three enclosed broiler breeder houses were selected to evaluate the effects of some environmental factors in different seasons along the year on F15 Hubbard broiler breeder chickens to provide reliable information and practical current knowledge for proper management conditions. Each house contains 4000 birds 25 Wk-old with average initial weight 2.560±50.60 kg, with a total of 12000 birds for three studied houses. Productive performances of flocks were evaluated by measuring egg production, egg weight, feed consumption, feed conversion of eggs and mortality rate. Also, egg quality traits were done for each season alone, while the physiological performance determined by measuring some blood traits. Further, fertility, hatchability and chick quality traits were also evaluated. Ambient temperature (AT, °C), relative humidity (RH, %) and concentrations of ammonia (NH3, ppm), hydrogen sulfide (H2S, ppm), carbon dioxide (CO2, ppm) and dust (mg/m 3), air velocity (AV, m/s) and static pressure (SP, Pa) were determined along the different seasons of the year. Results of the present study showed that air quality of breeder houses and either productive or physiological performance were significantly (P ≤ 0.05) affected due to seasonal changes along the year. High concentrations of different gases present in houses in winter season can negatively affect production and health of birds. In spring and summer seasons egg production and FCR were significantly (P ≤ 0.05) the best in comparison to the other different seasons. While, insignificant differences observed in egg weight due to seasonal changes. Mortality rate showed the highest percentage for birds reared in winter compared with the other seasons. In addition, there was evidence of an increased stress response due to elevation of environmental gases in winter and autumn seasons as judged by the increase of hetrophils, lymphocyte and H/L ratio and CS level reflecting the increase of stress due to environmental conditions. However, the levels of T3 and T4 recorded significantly higher (P ≤ 0.05) values for birds kept in winter season compared with the other seasons. Furthermore, egg quality traits had been significantly (P ≤ 0.05) affected due to seasonal changes, where the shell thickness recorded the highest (P ≤0.05) value during autumn and spring, while the lowest recorded for summer and winter seasons. Further, insignificant differences were detected for fertility, hatchability or chick quality traits due to seasonal changes. Based on the former results, it can be concluded that the tolerable temperature for the breeder was 19-28°C, but decreasing AT to reach to 25 °C is required in summer

“…In poultry houses, harmful gases like ammonia, carbon dioxide, methane, hydrogen sulfide and nitrous oxide, are generated by the hens and their waste (1,2). These gases may accumulate and reach toxic levels which may cause risk to the health of both chickens and the workers, therefore an adequate ventilation must be maintained.…”

“…In intensive poultry housing systems, laying hens should be kept in good environmental conditions, ensuring good care, in order to ensure that laying hens are performing to their maximum yield capacities within their genetic potential (1,13). Maintaining a proper ventilation can be costly for the farmers, but without it poor bird health and performance due to poor air quality can be much more detrimental to net returns.…”

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.
