Abstract: Most of modern broilers are reared in high-density houses，so a large number of toxic and harmful gases will be produced in the houses，which have adverse effects on growth performance，good health of breeder and natural environment of chickens，especially ammonia.Physical and chemical methods were combined to study effect of copper sulfate on ammonia absorption rate under high voltage pulsed electric field，principle was used to simulate ammonia absorption process in henhouse under high voltage pulsed electric field，and the model was constructed to achieve purpose of efficient removal of ammonia，which could provide beneficial help for broiler production.
