ISU to hold beef cattle nutrition field day June 11 near Ames

Iowa Beef Nutrition Showcase will spotlight feed efficiency trial results and other cattle feeding studies

A culmination of five years of extensive research through the USDA’s National Program for the Genetic Improvement of Feed Efficiency in Beef Cattle will be on display June 11, according to Iowa Beef Center director Dan Loy.

“Iowa State is one of the eleven universities involved in this USDA project that has genotyped and phenotyped more than 8,000 head of cattle from nine breeds across the nation to date,” Loy says. “We’re hosting a Beef Nutrition Showcase highlighting several outcomes of the project research on Saturday, June 11 at the Iowa State University Beef Nutrition Farm near Ames.”

How these tools are being used in real-world feedlot production

FEEDING CATTLE: Five years of research funded through USDA’s National Program for Genetic Improvement of Feed Efficiency in Beef Cattle will be on display June 11 at an ISU nutrition field day near Ames. One of the trials will feature an explanation of the new feed intake EPD measurement.

Set for 4:30 p.m. to 6:30 p.m. at the farm located about five miles northwest of the ISU campus in Ames, the event will provide opportunities for attendees to view multiple ongoing feed trials and learn how selection tools from the USDA grant are now being applied to real-world feedlot production. The exact address of the farm where the event will be held is 3405 North Dakota Avenue.

Patrick Wall, ISU Extension beef program specialist, says one trial will be of special interest to those wanting to learn more about expected progeny differences (EPDs.)

“One of the featured trials is testing the American Hereford Association’s new Feed Intake EPD, specifically to see if feedlot managers can potentially use a sire’s EPD for intake to enhance the management and ultimate profitability of a pen of cattle,” Wall says.

Other topics include residual feed intake test, and trace minerals

“The June 11 field day program also will highlight a Residual Feed Intake (RFI) test of Limousin cattle, a test of trace mineral interactions on a group of purebred Red Angus, and a zinc metabolism study on Angus genetics,” says Wall.

A steak sandwich dinner will conclude the event at the Hansen Student Learning Center on campus in Ames. There’s no cost to attend but people are asked to preregister by June 6 to ensure an adequate meal count. Preregister by calling Wall at 515-450-7665 or email him at [email protected].

The Iowa Beef Center at Iowa State University was established in 1996 with the goal of supporting the growth and vitality of the state’s beef cattle industry. It comprises faculty and staff from Iowa State University Extension and Outreach, College of Agriculture and Life Sciences and College of Veterinary Medicine, and works to develop and deliver the latest research-based information regarding the beef cattle industry.
