Animal Reproduction & Biotechnology Laboratory

​The Animal Reproduction and Biotechnology Laboratory is an interdepartmental program focusing on research, teaching and service in the area of reproductive biology of domestic animals. Faculty of the ARBL include members of three departments in two colleges. The ARBL has been recognized as a Colorado State University Program of Research and Scholarly Excellence since 1989. 

The Equine Reproduction Laboratory is a program within the Animal Reproduction and Biotechnology Laboratory. For information on programs specific to equine reproduction, visit their website.

  • Dolly the Sheep
    It's been 20 years since Dolly the sheep became the first mammal successfully cloned from an adult body cell. Dr. George Seidel, a CSU expert in reproductive technology, explains how cloning turbocharges traditional animal breeding.
  • assisted reproductive technologies
    Biomedical Sciences graduate students gain real-world experience with human-assisted reproductive technology.
  • Bison at soapstone release
    ​​Science and ceremony joined as American bison with distinctive bloodlines returned to the grasslands of northern Colorado. The wildlife conservation project employs CSU reproduction science and is cheered by Native Americans with cultural and spiritual ties to bison.​​
  • horse birth control
    CSU reproduction scientists are working on contraceptive vaccines that could provide safe and humane ways to rein in wild horse populations in the West, reducing the need for controversial roundups and sales.​​​​
  • dr. gordon niswender
    Dr. Gordon Niswender, who died in March, was a pioneering scientist in reproduction biology. He was also a cherished CSU teacher, mentor, and friend known for his kindness and for helping to dramatically grow our college research enterprise.​​​
