The ICPD, since it’s inception has been dependent on the generosity of institutions and sponsors
for its support. The organizing committee would like to recognize the major contributions
made by Michigan State University, Pfizer Animal Health, and the United States Department of
Agriculture. In addition, other important sponsors include
ABS Global

Introduction
The goal of the International Conference on Production Diseases in Farm Animals has always
been to unite scientists from many disciplines and many countries in the study of production
disease, and the 12th ICPD has met that goal. The breadth of national representation at the ICPD
continues to expand, as do the number of scientific disciplines represented. Disciplines such as
ethology and molecular genetics, which were little known at the beginning of this conference
series, have become important components of the ICPD.
In the preface to the proceedings of the second of these conferences, Dr. Jack Payne defined
production disease as “a number of metabolic disorders of increasing importance in agriculture”.
Over the years, this definition has expanded to include not only metabolic and nutritional diseases,
but also many diseases of an infectious and genetic nature. The common theme of all these
diseases is their association with management and selection of animals for efficient agricultural
production. We now appreciate that this association goes well beyond the important “input”,
“output”, and “throughput” equations of Dr. Payne’s. We must now work also to understand
the effects of management and selection on a wide variety of factors such as animal behavior,
immunity, and gene expression. The complexity of these interactions makes the interdisciplinary
nature of the ICPD even more important than before. The themes of animal welfare, health,
and productivity in agricultural systems go well beyond “metabolic disorders”, but they remain
“of increasing importance in agriculture”. Thus, the management and prevention of production
diseases will become evermore challenging as agricultural systems advance. These challenges
have provided rich and productive discussions for these ICPD proceedings, and should provide
continued themes for productive ICPD conferences for many years to come.
