This book briefly reviews the history of equine embryo transfer, covering in clinically practical terms the techniques, equipment, and management protocols currently in use. Embryo transfer has become a big business, especially for breeding racing stock (horses and camels), and is therefore a very important aspect of equine practice. Ed Squires and Pat McCue have been involved with the development... Read more

Biography
Patrick M. McCue, Edward L. Squires
"... a well-written book. It covers everything involved in equine embryo transfer work from start to finish. The book is written in a manner that will provide valuable information to anyone interested in learning embryo transfer or someone who is already doing some embryo transfer but would like more information. ... I particularly liked the pictures and charts, because they nicely complimented and augmented the text. This book also contains a lot of descriptive statistics for a large number of embryo transfers. It is a good value and will be a nice addition to the library of anyone interested in equine embryo transfer."
