This publication is a summary of the research conducted at the Carrington Research Extension Center Livestock Unit and with cooperating producers during the recent past. The mission of the livestock unit is to conduct research useful to producers for the development and enhancement of animal agriculture. The focus of the studies are on nutrition and management for both cow/calf and feedlot enterprises in beef and feedlot in bison. Some of the trials focus on alternative management systems and new or alternative feed sources that could lower production costs for cattlemen. This publication includes both progress reports and final summaries.

The Beef and Bison Production Field Day is held in conjunction with the summer crops field day to present a comprehensive review of all programs at the Carrington Research Extension Center in a one day event. Crop and livestock producers may choose from many different subject matter tours offered in the morning and/or afternoon.

Many of the studies conducted at the station are planned and executed in cooperation with researchers at other stations and in other disciplines. This cooperative spirit is important to accomplishing the mission of the experiment station system. Thank you to all who have participated in these studies. Appreciation is expressed to Karl Hoppe, Area Livestock Extension Specialist, Dale Burr, and Jackson Hagen, Livestock Technicians, David Copenhaver, other farm crew members and summer temporary employees for their efforts in support of research reported in this proceedings.

If you have comments, suggestions or ideas that you would like to convey to the staff at the Research Extension Center, please write or call: Carrington Research Extension Center, Box 219, Carrington ND 58421, (701) 652-2951. It is the goal of those involved in the studies reported in this publication that the information will be of interest and useful in your operations.

Sincerely,
