Awards, Lectures, and Conversations 



Science in Practice Award


Dr. Nathan Winkelman, DVM

Nathan Winkelman, DVM, president and co-owner of Swine Services Unlimited, Inc. (SSUI), is the 2019 recipient of the Allen D. Leman Science in Practice Award, which is presented at the annual Allen D. Leman Swine Conference in Saint Paul, MN. Dr. Winkelman caught the science bug early in his career and, thankfully, never found a cure for his orientation toward discovery.

Winkelman is an internationally recognized swine veterinary consultant. For over 30 years he has worked with progressive pork producers throughout North and South America and, more recently in China, on swine health and biosecurity, production management, and records analysis. However, his stellar career extends beyond excellence as a practicing veterinarian to include unique scientific contributions as well.

Early in his practice career, Winkelman became intrigued by the enteric disease porcine proliferative enteropathy (PPE, ileitis) caused by Lawsonia intracellularis. This was in part because so many client herds suffered from the malady, but also because establishing immunity to ileitis can be challenging. Since 1995, Winkelman has conducted scientific trials with an ileitis disease model, to whose development he was instrumental. This work and his interest in controlling the disease led to a 2012 patent for "diluted L. intracellularis," a method of providing controlled ileitis immunity in pigs.

"For more than 20 years this award has honored some of the most accomplished veterinary leaders in the swine industry," says Montse Torremorell, DVM, PhD, and professor in the Department of Veterinary Population Medicine at the University of Minnesota. "We are excited to recognize Dr. Winkelman and to have the support of Zoetis in supporting this award."

"Dr. Winkelman is an outstanding ambassador for integrating science into the practice of veterinary medicine," says Lucina Galina, DVM, PhD, and technical director at Zoetis. "We salute his long record of innovation and tireless pursuit of solutions that improve swine health around the world." Zoetis is sponsoring the reception at this year's Leman Swine Conference in Saint Paul, where Winkelman will be honored. The company is the world's largest producer of medicines and vaccines for pets and livestock.

Winkelman is the primary author of over 40 scientific articles, a book chapter, and coauthor of numerous other scientific articles on ileitis and other swine diseases. He routinely volunteers his time with various organizations and frequently presents clinical case reports to veterinary students. Winkelman is the current AASV president and has been active in that organization since 1982. He earned his BS in animal science from the University of Minnesota in 1979 and his DVM degree from the school's College of Veterinary Medicine in 1984. He and his wife, Deb Bryant-Winkelman, also a veterinarian, reside in Sartell, MN.

Morrison Lectureship

The Morrison Lecture will become a prominent feature of the Leman Program. This keynote lecture in honor of Dr. Morrison is given to individuals that do work that matters to the swine industry. 

The Morrison Lectureship is named in honor of Dr. Bob Morrison for his work in the areas of swine disease epidemiology and factors that drive productivity and economics in the swine industry. Throughout his distinguished professional career, Dr. Bob Morrison was an integral part of the swine community as a practitioner, professor, swine producer, researcher, veterinarian, mentor, and valued colleague and friend to many. 

Bob received his DVM from the Western College of Veterinary Medicine, University of Saskatchewan in 1976 followed by his PhD and MBA from the University of Minnesota.  Bob received many awards during his career, including being named one of the Masters of the Pork Industry in 2016 by the National Hog Farmer.  His work at the University of Minnesota helped lead the industry in the control of important diseases of swine from pseudorabies to PRRS, PED and beyond.  

Bob’s drive and passion invigorated everyone he touched and was evident in all aspects of his life and work.  He ably combined grace, sincerity, kindness, humor, and a great vitality.  He had a boundless sense of curiosity, with which he guided us to seek out answers with him. Dr. Morrison created the Swine Health Monitoring Project which provides the ability for the swine industry to detect and address emerging pathogens while delivering value and support to the program participants. Bob strongly believed in the importance of the MSHMP and its underlying mission to aid the swine community to improve animal health.  Dr. Morrison led the organization of the Leman Conference in the US and China and died on May 2, 2017 in a tragic car accident in the Czech Republic.

Pijoan Lecture

The Pijoan Lecture is named in honor of Dr. Carlos Pijoan for his work in the area of swine respiratory disease and the influence of swine production systems on the dynamics of microorganisms such as porcine reproductive and respiratory syndrome virus, Haemophilus parasuis, Streptococcus suis, and Mycoplasma hyopneumoniae. Dr. Pijoan received his veterinary degree from the National University of Mexico in 1969 and his PhD from the University of Surrey in the United Kingdom in 1973. In 1982, he joined the University of Minnesota College of Veterinary Medicine, where he was the founder and director of the Swine Disease Eradication Center and a professor in the Veterinary Population Medicine department.

Dr. Pijoan’s many honors and awards included the Norden Teaching Excellence Award in 1991, the Mark of Excellence Award in 2001, the Pfizer Award for Research Excellence in 2002, and Best Teacher awards in 1999, 2000, and 2001. Dr. Pijoan died on Jan. 9, 2007, after a three-year battle with pancreatic cancer.

The Kernkamp Lecture was created in recognition of Dr. Howard Carl Henry Kernkamp’s contributions to swine disease research. “Kernie”, as he was affectionately known, became interested in swine diseases early in his professional life, and was best known for his research in hog cholera, swine influenza, swine brucellosis, and the enteritis complex of swine. He was the author of over 30 articles and became known worldwide as a pathologist. He will also be remembered his talent of recalling and describing the history and significance of events in the development of Minnesota's veterinary medical profession, and his wit, humor, and “Kernie” dialect when telling some of his “tall tales”. They were “truths", only slightly embellished to make them more effective. 

Dr. Kernkamp attended the School of Agriculture at the University of Minnesota before entering the College of Veterinary Medicine at Ohio State University. While a veterinary student he worked summers at the State Anti-Hog Cholera Serum Plant on the University of Minnesota St. Paul Campus. Upon receiving his DVM degree in 1914 he was appointed instructor in the Division of Veterinary Medicine, University of Minnesota. He was assigned to the Diagnosis Laboratory and the Serum Plant, and later he was promoted to oversight of the Serum Plant. Dr. Kernkamp was acting assistant dean 1953−54 and retired in 1960, after 46 years as a University of Minnesota faculty member. He died of a heart attack on November 4, 1987, at the age of 95.
