Abstract:
The experiment aims to monitor changes in the environmental conditions inside the poultry house, a comparison between the times, the locations inside of the hall. Use 405 broiler chicken Rose-308. The results showed a significant effect among the measurement time, day and night, as it gave the highest temperature and lowest relative humidity during the day in comparison with the night, however no significant effect was recorded on dew point and carbon dioxide. The locations of the hall, the front of the hall outperformed in comparison with the middle and the end of the hall with in terms of the lowest temperature, highest relative humidity, dew point and lowest carbon dioxide level. The temperature during the day was higher than it was at night, and the relative humidity was the highest at the front of the hall at night and the lowest at the end of the hall during the day, and the dew point was the highest at the front of the hall during the day and the lowest at the end of the hall at night. As for carbon dioxide, it was not significantly affected by the interaction between the measurement time and location. Where the highest temperature was recorded at 28.44° C with time during the day and the location at the end of the hall, and the lowest relative humidity was 49.184% during the day in the center of the hall, with the dew point and carbon dioxide not being affected significantly. The evening hall’s starting locations outperformed with the lowest temperature of 26.169 °C, the highest relative humidity of 50.57%, and the dew point of 25.34 °C, while no significant effect was recorded for the site and time together on the level of carbon dioxide. There was no effect of the site on the live body weight, while it was found that there was a significant effect of the site in the fifth week in the average weekly weight gain, the first week of the feed intake and feed conversion ratio, as well as a significant effect of the site in the mortility ratio. Keywords: broiler, poultry houses, poultry environment, environmental factors, dew point.
