To raise pigs well, five major links must be grasped.

In the case of continuous market fluctuations in the development of pig farming, we should pay attention to four periods, namely: trough period, development period, peak period and decline period.

Bacterial disease of pigs-Haemophilus parasuis
Haemophilus parasuis, also known as fibrinous serositis and arthritis, is gram-negative bacilli, showing sporadic polyserositis and arthritis. With the development of the world pig industry, the application of large-scale feeding technology and highly intensive feeding, as well as the existence of sudden new respiratory syndrome and other factors, the disease is becoming more and more popular and the harm is more and more serious. In the past two years, it is not uncommon to report that Haemophilus parahaemophilus causes polyserositis and arthritis in pig farms, especially in large-scale pig farms.
