In experimental studies with birds, diagnosis and control of disease is an
essential laboratory support function that has great value to all investiga
tors within the research unit. Diagnostic support is best accomplished thro
ugh appropriate constellation and proper utilization of manpower, physical
facilities, equipment and financial resources. Control of disease is essent
ial for the generation of reliable and useful experimental data, and for th
e interpretation and application of such information in field or natural si
tuations. The simplified approach of disease control as the determination o
f an etiologic agent and the institution of a treatment plan is an outdated
approach to laboratory animal medicine, especially for avian species. Prev
ention of disease, not treatment of disease, is the most appropriate approa
ch to disease control and is paramount for the generation of reliable and v
iable scientific data.
