Animal Science 

[description of how partnerships with industry allow AnSci create unique and value added learning experiences for students]

Equine Reproduction Lab

The Equine Reproduction Laboratory is part of the Animal Reproduction and Biotechnology Laboratory in the College of Veterinary Medicine and Biomedical Sciences at Colorado State University. The CSU Equine Reproduction Program has developed leading-edge equine reproduction techniques for the equine industry for over 45 years. 

Current Research

Equine Genetic Preservation

This research aims to improve the ability to utilize frozen semen from more stallions, which would have a great impact on the equine industry.

Assisted Reproductive Techniques

Assisted reproductive technologies are widely used in the equine industry to provide more efficient use of valuable equine genetics and equine reproductive physiology. CSU has been a leader in this development.

Fertilization and Pregnancy

Thousands of foals are born a year, but the actual mechanisms involved in fertilization remain unknown. Two dilemmas related to reproduction include, an ever-growing desire to maximize reproductive efficiency and a need for an effective contraception protocol.

Reproductive Physiology

Reproductive physiology encompasses a wide variety of reproductive functions, including neuroanatomy and endocrinology, testicular and ovarian physiology, and physiology of the male and female reproductive tracts.

mare and foal

Reproductive Pathology

This research aims to develop accurate and sensitive diagnostic tests for detection of the presence of a reproductive disease or abnormality.


Continuing Education Registration

The Equine Reproduction lab has multiple opportunities for veterinarians and horse owners to continue their education, virtuallly or with hands-on work. 

Stallion Roster

The ERL barn house 10 stallions for the breeding season. The barn houses both CSU-owned stallions and client stallions from around the nation.

Stallion Auction

Colorado State University’s stallion auction supports continued equine research. The auction funds the CSU Equine Orthopedic Research Center and th CSU Equine Reproduction Laboratory.
