With the integration of new generation information technology such as artificial intelligence, big data, and cloud computing with the pig industry becoming deeper and deeper, the upgrading pace of equipment is gradually accelerating, and intelligent pig equipment continues to emerge, which greatly improves the efficiency of pig production.

Pigs in a long-term environment with high concentrations of ammonia are prone to respiratory diseases and eye diseases, which will also affect the appetite and growth of pigs, and reduce the productivity and economic benefits of pigs.

At present, the production technology and management level of pig breeding in China have been greatly improved, and the breeding scale has gradually expanded, but it also leads to a large amount of manure production and discharge.
