David Patterson

Dave Patterson, University of Missouri

Topic: Estrous synchronization protocol evolution and practical application

David Patterson is a faculty member in the Division of Animal Sciences at the University of Missouri. A native of Montana, he completed his bachelor's and master's degrees at Montana State University. Research for his master's was conducted at the USDA Livestock and Range Research Laboratory in Miles City, Mont. He received a doctorate in reproductive physiology from Kansas State University.

Patterson has received over $9 million in competitive funding to support his research program, and his publication record includes over 400 refereed journal articles, scientific abstracts, proceedings papers and presentations at national and international meetings. His research efforts have gained wide industry acceptance and resulted in new strategies to synchronize estrous cycles of postpartum beef cows and replacement beef heifers. Patterson’s research program received funding for the past 17 years from the National Institute of Food and Agriculture’s Competitive Grants Program, which led to the development of four progestin-based protocols to facilitate fixed- time AI in beef heifers and cows along with a modified breeding strategy using split-time AI.

Patterson led the development of Missouri’s Show-Me-Select Replacement Heifer Program. During the past 20 years, 843 farms have enrolled 136,499 heifers in the program. The program has facilitated the sale of 33,116 heifers in 151 sales across Missouri, with heifers sold into 20 states. It is the first statewide, on-farm beef heifer development and marketing program of its kind in the United States. The impact of the program on Missouri’s economy during the past 20 years exceeds $120 million.

Patterson was recognized as Man of the Year in Missouri Agriculture in 2001; was a past recipient of the American Society of Animal Science Extension and Animal Industry Service Awards in 2006 and 2007, respectively; the Beef Improvement Federation Continuing Service Award in 2010; the Frederick Mumford Outstanding Faculty Member in the MU College of Agriculture, Food and Natural Resources in 2012; the 2012 Research Award presented by the National Association of Animal Breeders; the 2013 NIFA Partnership Award for Mission Integration of Research, Education and Extension; the 2013 NIFA Partnership Award for Multistate Efforts; the 2014 C. Brice Ratchford Memorial Fellowship Award; the 2015 MU President’s Award for Economic Development; and in 2017 was named as one of “50 Missourians You Should Know,” Ingrams’s Kansas City’s Business Magazine.

Patterson served as chairman of the Beef Reproduction Task Force.


Randy Prather, University of Missouri

Topic: Next on the horizon for genetic technology

Since 1982 Randy Prather’s research has focused on the early mammalian embryo. He obtained his bachelor's and master's degrees from Kansas State University, and his doctorate and postdoc from the University of Wisconsin-Madison. While at Wisconsin, he cloned the first pigs, and some of the first cattle, by nuclear transfer. His group at the University of Missouri created miniature pigs that have the alpha 1,3 galactosyltransferase gene knocked out, thus paving the way for xenotransplantation. His group helped to develop pigs that have cystic fibrosis, thus providing the first whole-animal model that can be used to study the disease. More recently, his lab created pigs that are not susceptible to porcine reproductive and respiratory syndrome virus. His lab at MU has made more than 55 different genetic modifications for agriculture and medicine. He is the director of the NIH-funded National Swine Resource and Research Center.

In addition to his transgenic pig research, he and his collaborators have identified genes in the reproductive tissues of pigs and cattle that will help develop an understanding of the pattern of gene expression to reduce the 30% loss of pregnancies that naturally occurs in mammals. He has helped to acquire more than $113,000,000 in external research funding; $58,000,000 has come directly to MU.

He is currently a Curators’ Distinguished Professor in the Division of Animal Science at the University of Missouri.



David R. Smith

David R Smith, Mississippi State University

Topic: Systems approach to animal health

David Smith is the Hall-Davis Endowed Professor and Beef Program Leader at Mississippi State University College of Veterinary Medicine. He is a board-certified veterinary epidemiologist with interest in discovering how to improve the health, well-being and productivity of cattle, while benefiting human and environmental health.

He serves on the U.S. Secretary of Agriculture’s Committee on Animal Health.



Randall Spare

Randall Spare, Ashland Veterinary Service, Ashland, Kan.

Topic: Characteristics of successful breeding programs – A veterinarian perspective

Randall Spare has practiced in Clark County, Kansas, for more than 25 years. A graduate of K-State University School of Veterinary Medicine, he and four veterinarians at Ashland Veterinary Center (AVC) provide large- and small-animal care to a diverse customer base in a four-state radius centered in southwest Kansas.

Spare and his veterinary team manage the herd health for some of the largest registered Angus seedstock producers in the United States, as well as providing comprehensive services to commercial cow-calf producers and feedyards. He is also a commercial cow-calf producer and cattle feeder and is involved in an extensive heifer development program.

Herd health management, nutritional consulting, disease prevention and testing, genomic and reproductive services, equine reproduction and acupuncture are all services offered by the AVC team. The AVC bovine viral diarrhea (BVD) lab tests more than 30,000 samples each year to eradicate one of the costliest illnesses in beef production. In addition, AVC veterinarians and support staff are responsible for managing the requirements of international exports for cattle shipments.

Access to genomic information and a positive economic environment for cow-calf producers has resulted in the growth of AI and the use of genomic technology. Spare and the Ashland Veterinary Center provide complete reproductive services, including synchronization, AI, genomic testing and semen sales on several thousand head of commercial and registered cattle each year.

The bottom line to having “skin in the game” in today’s beef marketing environment is understanding what costs money or provides a chance to make a profit. Spare’s focus on whole-herd health, nutrition and genomic information is a result of collaborative relationships with his clients and his own commitment to understanding the many opportunities to add value to beef cattle, regardless of end point.
