Reduction of such effects should be a part of the planning of every project. For example, treatment with vitamin E and selenium at the time of capture improved the long-term survival of the northern bobwhite (Abbot et al. 2005). Many investigations of wildlife disease include some type of laboratory study and, because laboratory-bred animals are not available in most instances, animals captured from the wild are often used as subjects for such studies.
