4-Corners BCIA
Beef Cattle Improvement Association Bull Test 1949-present
Colorado State University was one of the first universities to establish a bull test for evaluating the performance of young bulls. Progeny from the breeding herd has been performance tested since 1949.
The elevation of the Four Corners Bull test is 7,600 feet making it the nation's only high mountain bull test. many of the cooperators as well as buyers run their cattle at high elevations and are concerned about costly losses to brisket disease (high altitude disease). BEEF magazine published an excellent article entitled "Faint of Heart" describing PAPs and their relationship to brisket disease.

| Bull calves were fed on an individual basis until 1980 when electronic feeders were installed and individual feed intake was measured and recorded by mini-computers. This provides feed conversion data for individual bulls and is helpful in evaluating the various lines of cattle in the herd. |  Photo courtesy of SJBRC Archives |
