Abstract:
This research experiment was conducted in the Latakia Governorate, during the period 2022-2023 during two seasons, summer (from July to August) and winter (January-February). To evaluate the pollution of ammonia (NH3) gas concentration in the indoor and outdoor air of the barn and the litter moisture content. When 3000 broilers belonging to the (Ross) hybrid. The results showed that the average concentration of ammonia gas (NH3) in summer season in the indoor air at the first week was 0.1 mg/m3, and in the sixth weeks, it increased to 9.7 mg/m3. While in winter season, the averages of concentrations were as the following: 0.5 mg/m3 and 20.4 mg/m3 respectively. As for the outdoor air of the barn, the research results showed a decrease in the gas concentrations in inverse proportion to the distance from the body of the barn. And for the average values of moisture of the broiler litter in the summer season at the first week was 26.54 %, while for the sixth week it reached 66.99 %, and in the winter season, the moisture content was 46.25 % and 75.36 % respectively.
Keywords: Ammonia gas (NH3), Broiler litter moisture, Summer season, Winter season.
