How much do you know about the importance of the ammonia detector to the breeding industry?

I. First, we will analyze the harm of ammonia to aquaculture, so that we can understand the importance of ammonia detector accurately.


1. The chicken's harm: ammonia is a toxic, colorless and has a strong pungent odor of gas, can feel the minimum concentration of 5.3ppm. Ammonia water solubility is high (0 degrees 1L water soluble 907g), it is often adsorbed on the chicken skin, mucous membranes and conjunctiva, thereby stimulating it and causing a variety of inflammation. There is information that, when the ammonia concentration was 20ppm the henhouse and lasted for 6 weeks, it will lead to pulmonary congestion and edema of chicken and chickens decreased appetite, laying rate decreased; at 50ppm days after the chicken will lead to occurrence of laryngeal edema, necrotizing bronchitis, pulmonary hemorrhage, respiratory rate decreased, and the emergence of the death of 80ppm; for 2 months can lead to the laying rate by 90%, increased mortality; up to 100ppm, the mortality rate will increase obviously. It can be said that the presence of ammonia has a great threat to the growth of chickens. The concentration of ammonia in the poultry house should be below 20ppm.


2. The harm to pigs:


Ammonia can cause rapid growth and metabolism of mucosal cells, it will cause the need of oxygen and energy increased, while ammonia detoxification process is a highly energy consuming process, therefore for animal growth and production of energy is reduced, thus affecting the growth performance of animal. According to reports the initial concentration of ammonia on livestock impact is 25 g/kg, 100 g/kg and ammonia concentration effects on growth performance is very obvious. In a closed part of the harmful gas in a pigsty that experimental study on growth performance of pigs, 50 g/kgNH3 level and growth efficiency of pigs decreased by 12%; 100 and 150 g/kg levels, growth efficiency decreased by 30%. The results showed that the daily gain decreased with the increase of NH3 concentration in the pig house, and the feed weight ratio increased with the increase of NH3 concentration in the pig house, and at the same time, it could induce other diseases.


II. Several aspects of the main performance of ammonia gas:


Reduce airframe resistance:


Ammonia in piggery inhaled through the respiratory tract, into the blood by alveolar, and hemoglobin, the heme into heme, reduce the oxidation of hemoglobin oxygen carrying capacity, blood alkali storage and heme, resulting in anemia and hypoxia, reduce the body's resistance to disease. Experiments show that, when the ammonia concentration reached 10 ~ 15 g/kg, will significantly reduce the animal's resistance to infection.


Induced disease:


Ammonia is recognized as the source of stress, is one of the most harmful gases in the animal shelter. The ammonia aqueous solution is alkaline, irritating to the mucous membrane, alkali burns can be serious, it can cause eye tears, pain, inflammation of the cornea and conjunctiva, visual impairment. Ammonia into the respiratory tract can cause cough, bronchitis and bronchitis, pulmonary edema, bleeding, dyspnea, asphyxia and other symptoms, or even necrosis, resulting in ventilator dysfunction. In addition, ammonia dissolves into mucus in the mucous membranes of the respiratory tract, allowing mucus pH to become alkaline, and cilia lose activity and increase susceptibility to airborne diseases. When the pig ammonia reached 15 g/kg, experimental pigs began to appear respiratory disease, atrophic rhinitis 35 g/kg, and with the increase of NH3 concentrations both rates are rising sharply, to verify the research reports from abroad. The ammonia concentration of more than 50 g/kg, can cause respiratory tract mucosa injury, atrophic rhinitis and other diseases epidemic outbreaks are positively correlated with the concentration of NH3 in pig. The study found that in winter, a large number of harmful gases such as pig houses and ammonia gas accumulated, which accelerated the occurrence of high fever (highly pathogenic avian influenza), and the mortality rate of the nurses was higher.
