This concept is known as biosecurity. Biosecurity refers to management practices that reduce the chances infectious diseases will be carried onto the farm by animals or people. Biosecurity also reduces the spread of infectious disease on farms. This relationship points out the opportunities for preventing infectious diseases. For example, producers can prevent some diseases by using vaccination to increase immunity.
Producers can also prevent disease by keeping infectious agents from coming onto their farm.
If an infectious agent is already on the farm, producers can try to eradicate it or control its spread within the farm. This is the basis of biosecurity. Strategic vaccination Vaccination is the essential component of disease prevention plans. Vaccination is likely to be most effective when it is planned to meet the particular needs of a farm. Setting up a strategic vaccination program means determining what diseases to vaccinate against, identifying who will most benefit from vaccination and finding out when they will most need the protection that vaccines provide.
