Meet Our SimSpecialists


Dr. Ken Odde
Bio:

Dr. Ken Odde

 Odde received a bachelor’s in animal science at South Dakota State. After a two-year stint in the US Army as an officer and platoon leader, he received a master’s degree in reproductive physiology, a doctorate of veterinary medicine, and a doctorate in physiology at Kansas State University (KSU). Odde taught at Colorado State University for 11 years, conducting research on beef cattle reproduction and health. He then returned to South Dakota, working for Pfizer Animal Health for six years, and AgSpan for three. 

Odde joined North Dakota State University in 2003 as head of the animal and range sciences department. He soon became the director of Beef Systems–Center of Excellence, which is a public-private partnership designed to grow cattle feeding and processing in North Dakota. In 2007 he became the animal sciences and industry department head at KSU; Odde recently retired from that role. 

In 1996, Odde and his wife, Arlene, purchased land in Pollock, South Dakota, which the family has since grown into a sizable commercial cow-calf operation. Today, they run 500 head of commercial SimAngus cows; Odde’s son John manages the ranch. In 2014, the family started an internship program to provide students with cattle experience. 

Odde has been involved with the Simmental breed for many years, participating in research, interviews, and industry events, and will be a valuable member of the SimSpecialists team.

Dr. Andy Roberts
Bio:

Andy was raised on a small irrigated crop and livestock operation along the Rio Grande River in southern New Mexico. In 1978, the family operation changed to raising registered Red Angus, from which Andy and his wife, Maddy, started their own herd of registered cattle in 1998. The couple continues to raise registered cattle with an emphasis on maternal traits. Andy received BS, MS and PhD degrees in Animal Science from New Mexico State University, University of Wyoming, and Washington State University, respectively. He served as the beef cattle Extension specialist at Washington State University for two years. In 1989, he accepted a postdoctoral fellowship in the Pharmacology Department in Vanderbilt University School of Medicine where he conducted basic research on mechanisms regulating follicular development, using cattle as the experimental model. In 1990, Andy was hired at the USDA ARS Meat Animal Research Center in Nebraska to conduct research on beef cattle reproduction. In 2001 he moved to the USDA ARS Fort Keogh Livestock and Range Research Laboratory in Miles City, Montana, where he conducted research for over 20 years evaluating nutrition and genetic effects on growth, reproduction, and economics during heifer development and cow lifetime productivity.

Dr. Jack Whittier
Bio:
Whittier was raised on a diversified livestock and crop farm in Northeastern Utah.  He received degrees from Utah State University and the University of Nebraska. He was on faculty at the University of Missouri for 9 years. In 1995, he joined the faculty in Animal Sciences at Colorado State University where he was the State Beef Cattle Extension Specialist.  During his academic career, he was actively involved in applied research of beef cow nutrition and reproductive management. Jack and colleagues developed some of the first ovulation synchronization protocols that facilitated increased use of timed artificial insemination across the beef industry.  Training graduate students was a key passion for him and watching his students progress into successful careers of their own has been especially satisfying.  In 2014 he was hired as Director of the Panhandle Research and Extension Center for the University of Nebraska located in Scottsbluff, NE. He retired in August 2020.  Dr. Whittier and his wife, Robynn, have two grown sons, two wonderful daughters-in-law, and five ambitious grandchildren.  Jack and Robynn also own a small-scale seedstock beef herd to produce SimAngus bulls and replacement heifers.

Gary served on the Bull Test Advisory Committee as a member/advisor during his tenure at Clemson University as the Simpson Station Bull Test Coordinator. He assisted the Animal and Veterinary Sciences Department with hundreds of practical laboratory experiences, teaching students Beef Cattle Management Techniques.  Gary has assisted the Clemson University Extension Service Livestock and Forages Team with numerous workshops.  These include Master Cattlemen Program, Artificial Insemination Classes (over 30 years), Cattlemen’s Boot Camp, Beef Quality Assurance, Bull Selection, Cattle Evaluation, Beef Production, and numerous field days.  

Gary served as the CU Bull Test Coordinator. The Clemson Bull Test is a performance test that culminates in a sale of eligible bulls. During Gary’s tenure, a GroSafe feeding system was installed making the Clemson Bull Test one of the first bull test east of the Mississippi to collect feed intake data. In addition to managing the bull test, he assisted/educated numerous producers on bull selection and EPD utilization.
