Winter Supplementation for Your Herd

November 21, 2019

7:00 p.m. CDT


During winter, many cattlemen and women utilize harvested forages and even crop residues to serve as the primary diet for their cattle when most grazing forages go dormant. However, many of these feedstuffs may not meet the dietary requirements of the animal. Join Dr. Tryon Wickersham, Texas A&M; Dr. Eric Bailey, University of Missouri; and Dr. Mary Drewnoski, University of Nebraska as they cover the importance of supplementing your herd when generally lower quality feedstuffs make up a majority of the animals diet specific to regions across the U.S.

Eric Bailey
Assistant Professor, University of Missouri


Dr. Bailey is the State Extension Specialist: Beef Nutrition for the University of Missouri Extension. He is a fifth-generation rancher raised on a commercial cow-calf and stocker operation outside of Santa Rosa, New Mexico. He has degrees from West Texas A&M University and Kansas State University. Research interests include fescue management for improved cattle production. Extension programming efforts include strategies to reduce reliance on purchased and raised feedstuffs for cattle producers.



Tryon Wickersham
Associate Professor, Texas A&M University

Dr. Tryon Wickersham and his family, Erin and two daughters, Katherine and Lydia, live on a small Angus Ranch that they run with his parents; near Kurten TX, just east of College Station.

He received a B.S. in Animal Science from Texas A&M University in 1998 and his M.S. & Ph.D. in Ruminant Nutrition from Kansas State University in 2002 and 2006, respectively.  He was appointed to an Assistant Professor position in the Department of Animal Science at Texas A&M University in 2006 and was promoted to Associate Professor in 2012. 

Dr. Wickersham teaches courses in animal nutrition at the graduate and undergraduate levels.  Dr. Wickersham’s excellence in teaching has been recognized by numerous teaching awards; most notably, he received the Association of Former Students Distinguished Achievement Award for Teaching at the University Level and the College of Agriculture and Life Sciences Dean’s Outstanding Achievement Award – Excellence in Teaching, both in 2013. Dr. Wickersham has served on the graduate committees of over 81 graduate students and advised 8 undergraduate thesis projects.

Dr. Wickersham’s research focuses on improving the economic and environmental sustainability of beef cattle production by improving the efficiency of forage utilization and the adoption of coproducts as a feed resource. Recently, he has worked on placing cows in confinement as a means of enhancing the sustainability of beef cattle production and using net protein contribution as a key performance indicator of sustainability.  Dr. Wickersham has been a contributor on research grants totaling approximately $3.95 million, since his arrival at Texas A&M. He is a co-author on 34 peer-reviewed publications and 114 abstracts.




Mary Drewnoski
