Oklahoma Panhandle State University Conducts Bull Test

For the 49th year, Oklahoma Panhandle State University (OPSU) conducted its Beef Bull Performance Test. The test is performed at the Oklahoma Beef Incorporated (OBI) central bull test station near Stillwater, Oklahoma.

Bulls are confinement fed for a 112 day post-weaning gain period. Their initial test weight, a 56-day weight and final test weight are measured, and the average daily gain is calculated.

"Producers participate to get performance information on their cattle, in order to ultimately improve their genetics," says Dr. Jerry Martin, OPSU Bull Test Director.

Typically, the bulls are sold to a commercial producer after the test period. The bulls range in age from 13 to 17 months old.

"These tests provide an insight into what the bull's progeny would do," says Martin. "Since most are sold to commercial producers, their calves go on to be stockers and feeders. Genetics indicate that by selecting good performing sires, weaning weights and average daily gain in the feedlot can be improved."
