Animal husbandry is an industry that is vital to the national economy and people’s lives. It is the core industry of agriculture and rural economy, and it is also a strategic industry required to ensure food safety and people’s housing. In recent years, my country’s animal husbandry has actively promoted supply-side structural reforms on the basis of maintaining stable output and quality, and has made great progress and development. In the production of major animal products such as meat, eggs, and dairy products, my country has always been at the forefront of the world. Animal husbandry is entering a new stage, constantly developing production capacity, improving product quality, and continuously enhancing comprehensive production capacity. Therefore, it is very important to do a good job in gas environment monitoring in farms.
Common toxic and harmful gases in farms
Toxic and harmful gases in farms refer to some toxic or odorous mixed gases produced by the feces and urine of livestock and poultry or the waste discharged from the processing of livestock and poultry products during the livestock production process. These harmful gases have many components, mainly ammonia, hydrogen sulfide, skatole, and mercaptans.
Ammonia (NH3): In livestock and poultry houses, ammonia mainly comes from various nitrogen-containing compounds, mainly produced by bacteria and enzymes decomposing feces, bedding and feed residues.
Ammonia is highly volatile and irritates the eyes and upper respiratory tract mucosa. It can bind to hemoglobin when entering the blood, causing tissue hypoxia. When the concentration is high, it causes livestock and poultry ammonia poisoning, and even causes respiratory central nervous system paralysis and death.
Hydrogen sulfide (H2S): In livestock and poultry houses, hydrogen sulfide mainly comes from fresh livestock and poultry feces and anaerobic degradation of sulfur-containing organic matter. When livestock and poultry eat high-protein diets and have indigestion, hydrogen sulfide production is high.
Hydrogen sulfide is a colorless, volatile, harmful gas with the smell of rotten eggs. It is a strong neurotoxin and has a strong irritating effect on mucous membranes. Low concentrations of hydrogen sulfide have effects on the eyes, respiratory system and central nervous system.
Mercaptans: Mercaptans are a group of organic compounds that are similar in structure to alcohols and have an extremely strong odor. Low-grade alcohols have a strong and disgusting odor, and the odor of ethyl mercaptan is particularly obvious.
Mercaptans mainly act on the central nervous system. Inhalation of low-concentration vapor can cause headaches and nausea, and high concentrations can cause respiratory paralysis and death. Poisoned people may vomit, have diarrhea, and have protein, casts, and hematuria in their urine.
Skatole: Skatole, also known as methyl indole, has a strong odor and is produced by microbial fermentation of undigested tryptophan in feed. Skatole can cause acute pulmonary edema and emphysema in cattle and sheep, causing huge losses to breeding.
Impact of toxic and harmful gases on livestock and poultry
Impact on pigs
Impact on chickens
Ammonia: Causes chickens to shed tears, respiratory inflammation, sneeze, slow growth, reduce egg production, and reduce disease resistance. It can cause a large number of chicks to die.
Hydrogen sulfide: can cause keratitis, and in severe cases, can cause paralysis of the chicken’s respiratory center and death. Low-concentration long-term poisoning can cause the chicken’s physical condition to decline and its ability to resist diseases to decrease.
Carbon monoxide: easily binds to hemoglobin in the blood and is not easy to separate, causing hemoglobin to lose its oxygen-carrying capacity, causing the body to be hypoxic and poisoned.
Carbon dioxide: Too high a concentration can cause the oxygen concentration in the chicken house to be too low.
Impact on cattle
Gas environment safety solutions for the breeding industry
Toxic and harmful gas detection and alarm devices
Farmers can install ammonia detectors, hydrogen sulfide detectors, temperature and humidity transmitters, liquid level transmitters and other intelligent detection instruments in the farm or manure pool to monitor the concentration of toxic and harmful gases such as ammonia, hydrogen sulfide, and carbon monoxide in real time. When the gas leakage concentration reaches or exceeds the preset value, the controller will send out an audible and visual alarm signal, and control the drive exhaust or other peripheral equipment to effectively prevent the occurrence of disasters and accidents.
GC510 portable gas detector
Chicheng Electric GC510 portable gas detector has two types: pump suction type and probe gun type, which is convenient for users to choose. Built-in high-quality sensors can work in an environment of -40℃~70℃, and detect the concentration of toxic and harmful gases in the farm in real time. The instrument shell is made of special high-strength ABS engineering plastics, which is durable, shockproof and fall-resistant. It can effectively prevent water, dust, skid and explosion.
The flammable and toxic and harmful gas detectors independently developed and produced by Chicheng Electric can be widely used in petroleum and petrochemical, chemical metallurgy, integrated pipeline corridors, animal husbandry, comprehensive shopping malls, catering canteens and other fields, escorting the safety of gas environment in all scenarios!
