Various pharmacological agents have been developed to block the immune response and the actions of cytokines. However, it should be recognized that the cytokines are necessary and beneficial for preventing infection in the animal. Also, it is unlikely that these pharmacological agents will be developed for commercial application in the pork industry. A common recommendation is to minimize immune stress. Isolation and testing of replacements, biosecurity and other methods are available to reduce the risk of introducing new pathogens to herds.
Producers are cognizant that drafts, cold, heat, crowding, air quality, etc. affect pig performance.
These basic management factors affect the immune system of pigs. Consequently, mistakes in fundamental animal husbandry create ideal opportunities for infectious agents to overwhelm the immune system of pigs. As biotechnology continues to evolve, it will not be surprising to observe new methods or treatments to overcome the influence of disease on pig growth. Meanwhile, pork producers currently know a fundamental solution to improve pig performance. Message Provide special attention to pigs during and after an illness.
