Biosecurity |
a collection of management practices which protect a herd from the entry of new diseases and minimizes the spread and/or adverse effects of disease within a herd -consists of a preventative approach to animal health -reduces the herd's risk for contracting or spreading disease -often only requires management changes HOW: -minimize exposure to disease agents (cleanliness) -develop immunity (vaccination) -manage environment to support both (nutrition, housing) very important: -education -improve the knowledge and attentiveness of the animal caretaker or manager
