Swine Respiratory Disease (SRD)

Swine respiratory disease is very common. Unfortunately, it is also very difficult to prevent and control. SRD can result in the depression of growth rates and feed intake. It can also have a significant effect on some herds in terms of loss of life.1

The control of swine respiratory disease requires an understanding of the interactions between the organisms that can cause this illness, the pig and the management of the environment.1

The prevalence of respiratory disease is affected by the following:1

  • The presence of the microscopic pathogens (organisms) that cause SRD
  • The virulence of the pathogens present
  • The level of the pathogens in the barn environment
  • The immunity of the pig and the time of exposure to the organisms
  • The interactions between pig, the environment and the management of the disease
