U.S. Meat Animal Research Center Turns 50

Center's research 'laid foundation for commercial ranches across the country'

Fifty years ago, Congress approved legislation that began the transfer of a Naval Ammunition Depot to the U.S. Department of Agriculture, thus creating the U.S. Meat Animal Research Center at Clay Center.

Since that time, scientists at the center and USDA Agricultural Research Service scientists at the University of Nebraska-Lincoln have grown its flagship genetics program and its germplasm evaluation project, which has evolved to be the largest breed comparison study over the last 35 to 40 years, said John Pollak, the center's director. The project also has information on how various breed crosses worked as composites.

"It laid the foundation for commercial ranches around the country," Pollak said.

USMARC houses both UNL and federal employees and also is the home to the Great Plains Veterinary Educational Center. 

During the last 15 years, capitalizing on its wealth of genetic diversity information, scientists began working in genomics and have been developing and refining genomic tools for use in selection by the industry, Pollak said.

"During that time period, the genomics group worked on the first case of BSE, using genomics to identify the origin of the animal," Pollak said. "It identified that particular cow was a Canadian animal, not a U.S. animal."

The program also produced marker tests such as those for tenderness and for the genetic defect osteopetrosis in Red Angus cattle.

In addition, USMARC was one of the collaborators, along with the University of Missouri, ARS Beltsville and the University of Alberta research teams, to work on the development of the original 50K SNP chip.

"Today, USMARC is sequencing their discovery population to better learn about the underlying mutation causing variation in economically relevant beef traits," Pollak said.

In the late 1990s, USMARC scientists began a focus on food safety and developed mitigation strategies for management of E. coli through the production cycle from the feedlot to harvest.

Scientists are now sequencing the genomes of E. coli and Salmonella to better understand the genetics behind antibiotic resistance, as well as to provide genomic DNA diagnostic tools to screen meat products for those pathogens.
