The Colorado Ram Test Association will begin its 18th annual ram-performance test June 6 at the Colorado State University Sheep Research and Teaching Unit near Fort Collins.
Rapid growth is a highly desirable selection trait in sheep.
The test gives producers valuable breeding and selection information and an opportunity to progeny-test their stud rams and still have lambs to sell. Lambs must be delivered to the university's sheep unit on May 28. University scientists will use ultrasound to check rib-eye area and fat thickness. The Colorado Ram Test is jointly sponsored by the Colorado Agricultural Experiment Station, Colorado State University Cooperative Extension and the department of animal sciences.
