This herd has been used extensively for study of the genetics reproduction and for development of new strategies for estrous synchronization and artificial insemination. The second research herd is located at the San Juan Basin Research Center in Hesperus, Colorado in the southwestern portion of the state. This station is currently in its 50 th year of beef cattle breeding research. A cooperator bull test is also a part of this center, now in its 47 th year of service. The breeding program currently consists of 340 cows.
Research focuses on composite lines of cattle.
A third herd of cattle is located at the Y-Cross Ranch near Cheyenne, Wyoming. This Hereford herd of 800 cows and 750 yearlings was recently gifted jointly to Colorado State University and the University of Wyoming. Plans are currently being made for this ranch to be used in the genetic evaluation programs of the American Hereford Association and Certified Hereford Beef program. One of the primary reasons for the strength of the CSU animal breeding program is the breadth of the program and its resources described above. Research Collaborators Faculty in the animal breeding and genetics program work closely with researchers from other leading institutes such as the National Animal Germplasm Program , Roman L. Hruska Meat Animal Research Center , Fort Keogh Livestock and Range Research Laboratory and the Institute of Veterinary, Animal and Biomedical Sciences, Massey University, New Zealand.
