High ammonia concentration leads to many serious problems inside the poultry houses. Different parameters are associated with the increased ammonia concentration that can accelerate the production of toxic gases inside the shed. Factors associated with high ammonia production are moisture contents of litter, ambient temperature, poor ventilation, humidity and related problems. For first 15 days of brooding, birds were kept under same conditions of management. These birds were divided into 5 distinct groups (A-E) and litter material of group C, D and E was treated with different modifiers (aluminum sulphate, aluminum silicate and Yucca extract), respectively. Temperature, moisture and microbial count of air and litter were observed. The duration of the trial was 4 weeks. Dropping composition, fecal appearance, clinical signs, breast and foot pad lesions were also monitored throughout the trial. High ammonia concentration was associated with the decreased weight gain, and increased FCR. It was noted that ammonia concentration was significantly (P<0.005) lower in treated groups as compared to the positive control group. The study observed the effect of increased ammonia concentration and provided the more convincing and affordable treatment to lower the ammonia production in poultry houses.
