2009 Test Information:

The first annual Doprer test is designed for Spring Born and Fall Born ram lambs that are at least 50% Dorper.  The main focus of the ram test is rate of gain during the 84 day test period.  However, scrotal circumference, wool covering and rib eye area will also be measured.  The idea behind a performance test is to place the animals in a central location under the same management so that as many environmental factors can be controlled.  Therefore, the differences between performance are more likely to be genetic differences rather than environmental differences.

Location:  The test is conducted annually at the Angelo State University, Management, Instruction and Research Center located north of San Angelo, Texas.

Purpose:  Angelo State University's Department of Agriculture in conjunction with the Texas Agricultural Experiment Station, San Angelo, Texas conducts a Dorper ram performance test annually to identify superior rams.  The test is an avenue for producers to bring their rams to a central location where they are managed with other producers' rams so that performance may be compared. 

Performance testing is crucial for a producer to really know how their rams compare to other producers' rams, but to accurately make the comparisons, the data must be taken from a performance test.  Performance testing is designed to remove many of the environmental factors that influence the performance of animals and if all animals are raised under the same conditions the data is comparable among animals.
