ARS animal scientist to discuss impacts of limited feeding on beef cows Friday

Published on Tuesday, March 9, 2010 3:16 PM MST

Andy Roberts, a research animal scientist and physiologist with the USDA Agricultural Research Service’s Livestock and Range Research Laboratory in Miles City, is the fifth speaker in the Northern Plains Agricultural Research Laboratory’s (NPARL) 2010 Brown Bagger series. His presentation titled “Beef cow longevity and efficiency with limited feeding management” is set for noon on Friday in the Sidney ARS lab’s Technology Transfer Room.

The public is invited to attend. The presentation runs from noon to 1 p.m. and the lab is located at 1500 N. Central Avenue, Sidne.

In his presentation, Roberts will review results from a long-term research project initiated in 2001 to evaluate “the influence of providing decreased amounts of harvested feed during heifer development and winter supplementation on lifetime productivity.” According to Roberts, results presently indicate that restricting levels of feed during postweaning development and throughout winter supplementation can actually improve production efficiency. Roberts says evidence suggests improved production efficiency is “due to decreased utilization of harvested feed and increased efficiency of cows” and that limited feeding management appears to alter the cow’s partitioning of nutrient utilization (i.e. increased body conditioning scores and decreased calf weight) that results in increased retention of cows beyond five years of age.”

Remaining speakers in NPARL’s 2010 BrownBagger series include the following:

• March 19: Irrigation “Mini-Workshop” with Tyler Tjelde, irrigation specialist, Williston Research Extension Center, and Robert Evans, agricultural engineer, USDA-ARS-NPARL (Please note: this event may extend past the regular noon hour to allow the two speakers more time to present and to ensure that all questions from interested participants can be addressed.)

• April 9: Robert Lartey, NPARL research plant pathologist, speaking on “Influenza virus and Turnip vein clearing tobamovirus: Mystery of viruses resolved!”

Additional information on upcoming presentations will be announced in local newspapers. For more information, contact Beth Redlin at 406-433-9427.
