In recent years, the domestic pig breeding program continuously expand, the breeding density and it is difficult to drop, facing the pressure of environmental protection, and respiratory disease happens, etc., and more and more difficult, completely rely on drugs and vaccines and cannot handle big disease, at present a lot of experts and farm owner pay more and more attention to the improvement of breeding environment, as well as the harmful gas such as ammonia more clear know, especially large and medium-sized formal pig is facing the urgent need to deal with problems. Many pig farms will use ammonia gas detector for testing, in order to achieve good testing role must choose the quality of good, accurate standard ammonia gas. Newradar customizes calibration gas for you according to your requirements, and a professional logistics team can deliver it to you all over the country

Ammonia measurements inside the pigsty showed that the closed pigsty had a target of 10ppm, while the others had a target of 5 to 7ppm and had almost no odor. PS: the maximum allowable value of ammonia approved by the national institute for occupational safety and health is 11ppm. Based on the safety baseline of toxic gases, the maximum baseline of whether or not there was an impact on the growth and health of pigs and whether or not there was an impact on the health of workers in the pigsty, the institute's staff came up with a target for ammonia of 11ppm for pigs, 7ppm for workers, 1500ppm for carbon dioxide and a particle index of 1.23mg/m3.

In recent years, the farm planned to have 1200 sows before the establishment of the deodorization tube, and the farms with 40% waste and death rate due to multiple system failure syndrome and other diseases of weaned pigs were visited. From the beginning of a month after the establishment of the deodorization tube, the monthly diarrhea density of pigs decreased, the waste death rate also began to gradually reduce, the growth rate also began to accelerate. In 2006, 25,000 were listed, and in 2007, 30,000 were listed. Now, the total waste and death rate is less than 5%. The average weight in Japan is 110kg. Now the farm grows to 165 days, with a maximum of 180 days. Inside all of the farm's pigsties, ammonia levels were below 10 parts per million.

Ammonia to pig formation damage may be far beyond our fantasy, include to the pig's growth, respiratory resistance, heat adverse effects of labor reproduction links such as pregnancy, and because of that, so Europe and the United States and other developed countries have already asked pig farms to strictly control the inner of ammonia, the European Union requires control in 10 parts per million, the United States insist on control in 15 parts per million, the ammonia in piggery first originated from pigs out every day a lot of excrement and urine of degradation and decomposition, in a cold season (winter season), in order to heat preservation in the closure of the status of the delivery room and conservation of inner, produce a lot of ammonia every day, Hydrogen sulphide and carbon dioxide are stored in the house, gradually increasing in concentration, especially damaging. The above materials show that the ammonia test in the feeding plant can not be ignored.
