Recent Updates on Freezing Equine Embryos

June 02, 2016

Posted by Dr. Ed Squires in Mare Management

The majority of equine embryos are collected from the donor mare and transferred immediately as fresh embryos or shipped cooled to a recipient station for transfer within 24 hr. You can learn more about the basics of embryo transfer (ET) in our article, Embryo Transfer and Frequently Asked Questions. Very few equine embryos are frozen despite the numerous advantages of embryo cryopreservation. We discuss the process of freezing embryos in our article, Cryopreservation of Equine Embryos. However here is a quick review of some of the advantages of freezing embryos are:

How to Manage the 'Slow' Stallion in the Breeding Shed

April 28, 2016

Posted by Dr. Dave Scofield in Stallion Management

Training 3 Juvenile and older males entering a new career as a breeding stallion don't have the luxury of a changing cascade of hormones or an event like parturition to jumpstart their innate nature to show them how to be a stallion. There is likely only a change in routine, location, or in their training schedule that cues them into their new roles as breeding animals. Many stallions make the transition seamlessly. Simply acting on the behavior they have been trying to use for years, allowing their behavior to mimic their springtime rise in testosterone. When exposed to a female, they have little doubt about the job at hand and will readily take to live cover or phantom training. Additional information for training the young stallion for collection can be found in our article, Collecting Semen from the Young Stallion. However, for some, the transition proves far more difficult and oftentimes frustrating for the stallion and for the staff at the shed.

What Can Cause a Mare to Lose Her Pregnancy?

April 01, 2016

Posted by Karen Wolfsdorf, DVM, DACT in Mare Management

What Can Cause a Mare_Ascending placentitis originating at the cervical starMares can develop problems during pregnancy or be at high risk of losing the pregnancy for a variety of reasons. These include age (old mares frequently have endometriosis in which the uterus is unable to properly supply the fetus with appropriate blood supply and nutrients), physical conditions (placental and fetal fluid abnormalities; body wall tears; chronic debilitating conditions such as laminitis and Cushing’s disease), and acute disease or injury (placentitis, uterine torsion, surgical colic, colitis, acute laminitis, or fractures). When a mare becomes stressed or debilitated, inflammatory chemicals and prostaglandins increase and induce abnormal uterine contractions and potential pregnancy loss. Reproductive problems that arise during gestation, however, when detected and diagnosed early, can still result in the survival of the mare and usually the foal. The abnormalities most commonly seen during the middle to late stages of pregnancy will be discussed in this article.
