To maintain a high stable level of productivity, intensive broiler farming technologies require in-depth knowledge in the field of feeding and keeping poultry. Numerous studies by Russian and foreign scientists indicate the need for animal specialists to understand the relationship between various indicators of the microclimate of the poultry house, the composition of the diet and technological aspects used in poultry farming and its impact on the health and comfort of livestock. One of the urgent problems with indoor broiler farming is the high level of ammonia in poultry houses. The paper considers the mechanisms of development of pathological processes in different tissues, systems and organs of the body of broiler chickens when exposed to this highly toxic compound, which negatively affect the well-being of poultry and naturally lead to a decrease in its productivity. The factors determined by the composition of the diet, technologies of feeding and keeping poultry, as well as the quality of microclimate management in the premises for growing broilers, leading to the accumulation of gas that exceeds sanitary and hygienic standards, are listed. An overview of ways to reduce the toxic concentration of ammonia in poultry houses is given, including control of ventilation and temperature in the poultry house, humidity and pH of the litter, as well as the level of nitrogen emitted with poultry droppings
