If you’re sure the nutritional needs of nursery pigs are being met and you’re still seeing fallouts, it’s possible you’re dealing with swine respiratory disease (SRD).

According to the National Animal Health Monitoring System, SRD is the prevalent cause of death in the nursery pig and grow-finish phases of production.

More often than not, multiple agents are involved. When more than one agent is circulating in the building, they act together to increase the severity and duration of disease.

Certain environmental factors can help transmit and increase the severity of the swine respiratory disease complex. Environmental factors that contribute to SRD include:

  • Overcrowding
  • Frequent mixing of pigs
  • High humidity
  • Dust
  • High ammonia levels
  • Temperature fluctuation

Working to minimize these factors can help improve pig health. In addition, consult with your veterinarian and request diagnostic tests to identify the specific disease agents present in your nursery.

Proper diagnosis allows you to determine the most effective prevention and treatment options to implement in your operation.
