Using of Diagnostic Facilities
Many times an accurate
diagnosis of a swine health
problem can be established on the
farm by experienced clinical
observation or by using a necropsy
(autopsy) of representative
animals. Other times these ob
servations lead only to a dif
ferential diagnosis so additional
aid is needed by the laboratory to
make the final determination.
An accurate-diagnosis is. very

Since diseases are reportable

accurate diagnosis becomes ex

Routine serveilance of slaughter
sows and boars is a valuable lab
service to monitor herd status.
Most lab diagnostic “failures"
result from farmers sending non
representative specimens or from
sending animals that have died
hours before presenting them to
the lab, especially in warm
summer months. Many bacteria
and viral diseases are heat sen
sitive and don’t survive for a long
period after the animal dies.
In some health-related problems
there is a nutritional or en
vironmental problem rather than a
disease-causing problem. This
dictates that an on-site evaluation
be done before blaming some
\ </
exotic disease as the causitive
agent and then expecting the lab to
find it.
