Dr. William B. Ley,

Dr. Ley enjoying the races on a sunny afternoon.

Dr. William B. Ley has been in the northern Virginia area (NOVA) since 2001. He was the head veterinarian at REACH, LLC in Millwood, VA before joining Dr. Waldron at Rectortown Equine Center in July of 2005. He now operates his own private practice and bases his breeding and wellness services out of Cloverlone Broodmare Farm's barn near Marshall, Virginia.

 

Dr. Ley is a board certified specialist in equine reproduction. He has 30 years of practical experience in general equine medicine, as well as being a highly trained reproduction expert.

 

He has 21 years of teaching and research experience in equine medicine and reproduction through his professional associations with the University of California at Davis, Davis, CA, Texas A & M University, College Station, TX, the VA-MD Regional College of Veterinary Medicine (VMRCVM), Blacksburg, VA, and Oklahoma State University College of Veterinary Medicine, Stillwater, OK.

 

As Head of the Department of Clinical Sciences at Oklahoma State, he was in charge of the clinical training programs for all third and fourth year veterinary students. Many of his former veterinary students at VMRCVM and Oklahoma are practicing in the NOVA and Mid-Atlantic States area. During his academic career it is estimated that he taught well over 1500 veterinarians in the USA and world wide.

 

Dr. Ley developed the Foal Watch TM milk calcium test. He has published well over 70 refereed and scientific journal articles. He is often a hired speaker on equine reproduction across the country.

 

Dr. Ley has been an participant in the equine industry as a breeder his entire life, and currently stands Margie Engle’s retired Grand Prix jumper, R-Saluut II, 1989 Horse of the Year. Bill and Gail run a Holsteiner sport horse breeding operation producing top youngsters for future primarily in hunters and jumpers as well as dressage, eventing, driving and foxhunting.

 

 

Dr. Ley, author of:

Broodmare Reproduction, Made Easy Series for the Equine Practitioner is available through the publisher, Teton New Media, Jackson Hole, WY, and on-line at Amazon.com.

 

Dr. Ley has contributed articles to horse industry and livestock
publications including EQUUS, The Virginia Horse Journal, Modern Horse Breeding, Horses and Things, Virginia Farmer, Farm and Country, and the
Virginia Cooperative Extension Service’s Livestock Update. In
recognition of his efforts on behalf of the horse industry in Virginia, he was honored by the Virginia Horse Council as Educator of the Year in
1998. His book, Broodmare Reproduction, Made Easy Series was written for veterinary practitioners and students, but is also a useful study guide for serious horse breeders. It is available to the public through
Amazon.com.
