UW Extension publication shows cost estimates to build stackyard fence

Cost estimates and benefits of fencing haystack yards to limit attracting elk and possibly decreasing brucellosis risk to cattle are described in a new bulletin from the University of Wyoming Extension.

Researchers in the Department of Agricultural and Applied Economics at the University of Wyoming provide cost breakdowns for a stackyard fence that meets Wyoming Game and Fish Department (WGFD) construction recommendations. The publication is The cost of brucellosis prevention: Fencing stackyards, B-1232.

The WGFD provides fencing materials where elk-cattle commingling is a concern; the producer covers installation costs. The bulletin provides total cost of materials provided by the WGFD, total tools and materials cost not provided by WGFD and estimated labor.

The publication is available free on the Internet.  Go to and click on Publications on the left-hand side of the page. Click search bulletins and enter B-1232 in the Publication Number field.

Brucellosis testing and research expanding in Wyoming

University of Wyoming Laboratory Assistant Tracy Dunn performs diagnostic testing for brucellosis at the Wyoming State Veterinary Laboratory. In October, the state veterinary laboratory tested nearly 9,400 animals for brucellosis.

When two heifers on a ranch near Meeteetse tested positive for exposure to brucellosis this fall, technicians from the University of Wyoming State Veterinary Laboratory quickly tested more than 320 other cattle in the area in addition to the 250 tested in the source herd and determined that the disease had not spread.

A year earlier, more than 4,200 animals were tested shortly after brucellosis was reported in northern Wyoming, said Walt Cook, who coordinates brucellosis research at UW.

The ability to conduct such rapid testing is one example of how legislative support to combat brucellosis is paying off to the benefit of the state’s cattle producers, Cook said. He said brucellosis is a bacterial disease that can cause domestic cattle, elk and bison to abort their calves. Elk and bison of the greater Yellowstone area of Wyoming, Montana and Idaho are a reservoir of brucellosis in the United States, so the disease is a concern for cattle producers in that area.
