Several measures to reduce

1.In order to avoid the excessive concentration of ammonia accumulated in the chicken cages, the manure and cushion of ammonia gas on the chicken cages, especially in the high temperature and humidity environment, should be removed in time to eliminate the source of ammonia gas and ventilate in time.

2.Maintain the chicken house dry ventilation in many parts of our country summer temperature, humidity is very high, should pay attention to cooling and moisture prevention. In addition to doing a good job in winter insulation, more attention should be paid to the indoor sewage dehumidification, to regularly open the exhaust fan and increase the air vent, in order to keep the indoor air fresh. When the concentration of ammonia in the room reaches 20 ppm, a strong smell of ammonia can be smelled. At this time, it is necessary to ventilate immediately, so that no stuffy, no pungent sensation after entering.

3.Biological ammonia removal method has been studied, lactobacillus can reduce the production of ammonia in chicken manure, EM preparation also has the effect of controlling the elimination of ammonia. The use of antibiotic free biological feed is the most effective and convenient biological nitrogen removal method. Bio-feed without antibiotics uses digestible raw materials to reduce the discharge of nitrogen sources, which contains rich lactobacillus, yeast, bacillus and other beneficial microbial viable bacteria, can degrade nitrogen-containing organic matter, reduce the production of ammonia. Using antibiotic free biological feed, ammonia concentration can be reduced by more than 70%.

4.Physical ammonia removal method hangs in the chicken cages into the  bag of charcoal, using the adsorption of charcoal, can reduce the concentration of ammonia in the air, at the same time properly sprinkle some activated carbon, cinder, quicklime and other adsorptive cushions on the ground, can reduce or even eliminate ammonia in the air to varying degrees.
