As teaching, research and service expanded, the Animal Reproduction Laboratory (ARL) was established to bring together scientists with a common interest in reproductive physiology of cattle and horses. The ARL attained an international reputation for research and short courses on cattle and horse reproduction. In 1972, Colorado State University recruited additional faculty and dedicated facilities to the area of reproductive endocrinology.
In 1986, the ARL completed a refocusing of objectives. Faculty had concluded that greater emphasis should be given to research leading to new principles in reproductive biology. In keeping with this new commitment, the name of the laboratory was changed to the Animal Reproduction and Biotechnology Laboratory (ARBL) in 1989.
Five new faculty members with expertise in cellular and molecular biology were recruited. Production of transgenic animals became a major research tool.
In 1989, the Colorado Commission on Higher Education selected the ARBL to be a state supported "Program of Excellence." The University named the ARBL as one of the first eleven "Programs of Research and Scholarly Excellence." The ARBL also is a WICHE (Western Interstate Commission on Higher Education) Regional Graduate Program, allowing in-state tuition to students from WICHE states.
Researchers associated with the ARBL have international reputations, having received over 20 major awards for excellence in research and service and have been elected as officers of major professional societies. One is a member of the National Academy of Sciences. Many serve on the editorial boards of major journals devoted to reproductive biology and reproductive endocrinology and sit on national review boards for research funding.
