“Tipping Point” Concept of Pig Disease
There is a saying, “when a butterfly flaps its wings in one place, a tsunami may occur in another place.” This is obviously an exaggeration, but the point is that small things can have great effects. This is the essence of the “tipping point.” The concept of tipping points has major impact on understanding swine health and production.
Although its principles are clear, a disease-control program including biosecurity doesn’t always work for all farms. No single “recipe-style” program will always work under all situations in any pig farm. Each farm is on its own “unique” situation that sets it apart from other farms. A disease may strike separate herds but the approach to its control differs from farm to farm.
This is because the combinations of risk factors leading to “explosion” of disease are not the same for all farms. When a disease breaks out in a herd, it indicates that risk factors have crossed the “tipping point” for that disease.
