Pig farmers are afraid of pigs getting sick, and the quality of the natural environment in pig farms directly affects the health of live pigs. Besides the significant impact of temperature on pig fattening that we discussed, the concentration of carbon dioxide and ammonia in the pigsty has not been given much attention to its effects on pigs.

The composition of the atmosphere outside the pigsty is relatively stable,Due to the breathing of pigs inside the house,excretion,Feed and its excrementDecomposition,On the one hand, it makes the airO2Reduce, increase carbon dioxide, while also producingNH3TheH2SHarmful gases such as methane. The polluted air inside the pigsty indicates an increase in the concentration of harmful gases, which will seriously affect the health of pigs and lead to a significant decline in production performance.

1Ammonia（NH3）It is a colorless gas with a pungent odor, and the air does not contain ammonia. The ammonia in the house is produced by the decomposition of organic matter such as feces, urine, feed, and bedding. Ammonia is easily soluble in water and can cause inflammation of the respiratory mucosa and conjunctiva in pigs. In severe cases, it can lead to necrotizing bronchitis, pulmonary edema, cloudy eyes, and blindness. In addition, due to the high concentration of ammonia, it can reduce the resistance or disease resistance of pigs, induce the occurrence of some diseases, and make it difficult to treat. The ammonia content in the pigsty should not exceed26ppm.

2Carbon dioxide（CO2）It is a colorless, odorless gas with a sour taste. The concentration of carbon dioxide in the atmosphere is approximately0.03-0.04%The increase in carbon dioxide content in pig pens is due to the respiration of pigs. The carbon dioxide content in well ventilated pig pens is0.06-0.18%In poorly ventilated pigsties, the concentration can reach0.3-0.5%Carbon dioxide itself is non-toxic and harmless, but excessive levels in pig pens can cause deficiencies in the bodyO2Causing weakness and decreased appetite in pigs,Weight gain decreased and incidence rate increased.

3Carbon monoxide（CO）It is a colorless and odorless gas, an invisible killer, and does not contain carbon monoxide in the atmosphere. The carbon monoxide in the house mainly comes from heating with a coal stove during cold weather. Therefore, in cold regions in winter, heating safety is more important. If a coal stove is used, a flue can be installed or other electric heating methods can be used.

4Hydrogen sulfide（H2S）It is a colorless and foul smelling toxic gas. Hydrogen sulfide in pig pens comes from the decomposition of sulfur-containing organic compounds. When pigs feed on high protein feed without sufficient digestion, hydrogen sulfide can be produced and excreted, which not only reduces productivity but also affects pig health, directly causing or inducing respiratory and conjunctival diseases. The presence of low concentrations of hydrogen sulfide can cause chronic poisoning. High concentration hydrogen sulfide isNeurotoxic agents can directly cause inhibition of the respiratory center, leading to suffocation and death in pigs.

How to effectively prevent it?

In order to create good growth and fattening conditions for pigs and ensure the safety of breeding, Haiyi Technology's toxic and harmful gas detector is installed in the pig farmMS400According to national regulations on the allowable concentration of toxic and harmful gases, real-time detection of the concentration of toxic and harmful gases is carried out to avoid harm to human and pigs caused by exceeding the concentration of toxic and harmful gases.
