Animal agriculture holds a spe
cial place in my heart because I
grew up on a grain and livestock
farm in central Illinois. I was
quite active showing Angus cattle
in 4-H and FFA and was on the Il
linois 4-H livestock judging team.
I attended the University of Illi
nois and received a B.S. degree in
Agricultural Sciences in 1971.
As an undergraduate, I was on the
University of Illinois Meat Judg
ing Team. I enrolled in graduate
school at the University of Illi-

UNIVERSITY PARK, (Centre Co.) —After
32 years as an educator, extension specialist
and researcher, Dr. Lowell Wilson, professor
of animal science in Penn State’s College of
Agricultural Sciences, is retiring from the
Department of Dairy and Animal Science.
Wilson earned a bachelor’s degree in agri
cultural education from the University of
Wisconsin-Platteville in 1959. He earned a
degree in animal breeding and statistics in
1962 and a doctorate in animal breeding and
biochemistry in 1964, both from South
Dakota State University. From 1964 to 1966,
he was an extension beef specialist at Purdue
University, where he was responsible for cow
calf systems. He also was responsible for ini
tiating electronic record processing for Beef
Cattle Improvement Associations in South
Dakota and Indiana.
Wilson has been with Penn State since
1966. His primary research focused on beef
cattle breeding and forage utilization, with
emphasis on the interpretation and reporting
of research results from Penn State and other
institutions to producer groups and industry
media. Since 1986, he has conducted special
fed veal management research, including
quality assurance and interpretation of public
perceptions about veal production.
His recent research has included the han
dling and transportation of animals, public
and producer perceptions of farm animal pro
duction practices, recycling of agricultural
and other by-products as livestock feed, and
effects of growth promotants on animal per
formance and carcass characteristics. He has
published or co-authored more than 130 peer
reviewed scientific journal articles, more than
500 industry-oriented articles, and several
monographs and book chapters.
Wilson has taught undergraduate and
graduate courses at Penn State and has
designed and taught courses in the
Pennsylvania Governor’s School for the
Agricultural Sciences. He was instrumental
in establishing the Pennsylvania Beef
Council, Pennsylvanians for the Responsible
Use of Animals, the Pennsylvania Beef Expo,
Pennsylvania Cattlemen’s Association sum
mer field days, and other educational activi
ties.
He received awards from the American
Forage and Grassland Council in 1975,
American Society of Animal Science in 1973,
the Northeastern Section of the American
Dairy Science Association/American Society
of Animal Science in 1993, the American
Polled Hereford Association in 1974, and .
Gamma Sigma Delta in 1974.
nois and received an M.S. degree
in 1974, then went to the Univer
sity of Minnesota to study how
certain hormones regulate growth
of meat animals.
In 1978, I received my Ph.D.
and moved to Stanford University
for a postdoctoral fellowship in
the Department of Medicine. My
objective was to become an endo
crinologist (the science of study
ing hormones and their biological
effects). I joined the faculty in the
Department of Dairy and Animal
Science at Penn State in 1979 and
rose through the ranks, receiving
the title of Distinguished Profes
sor of Animal Nutrition in 1996.

I was actively involved in
teaching growth biology and nu
tritional biochemistry courses to
undergraduate and graduate stu
dents. The emphasis of my con
tinuing research program is on de
veloping new biotechnologies to
increase productive efficiency of
growing pigs. In the 1980 s, we
played a fundamental role in dis
covering that porcine somato
tropin (pST) increased muscle
growth and decreased fat in grow
ing pigs. This discovery
prompted several pharmaceutical
companies to undeitake efforts to
commercialize the technology.
Since then, my laboratory has fo
cused on learning more about the
biological mechanisms that ex
plain how pST works.
During my travels throughout
the Commonwealth, I have
learned there is a real need for the
faculty and staff in Dairy and
Animal Science to inform you
about the department, our mission
and our teaching, research and ex
tension programs and how they
benefit you. I believe it is impor
tant that we in the department
communicate effectively and in a

timely way with our stakeholders.
To foster this dialogue, I invite
you to contact me to share your
perspective about our programs.
You are shareholders in the Uni
versity, and we feel an obligation
to seek your input as well as to
share our insights and expertise
with you. Our faculty members
are committed to this philosophy
and are enthusiastic about partici
pating in this outreach activity.
Different faculty members have
agreed to address a variety of excit
ing and timely topics on a regular
basis. Articles in future issues of
Lancaster Farming will cover all
dairy and livestock species and
will update you on our teaching
programs, promising results of re
search, and useful and practical ex
tension education information.
Periodically, I will write a col
umn like this to inform you about
important events, newsworthy
items and issues that will impact
animal agriculture. I want to dis
cuss the future of animal agricul
ture in the 21st century and share
my vision of how animal agricul
ture will need to change to thrive
in the next century.
