Featured News: Introducing A Nurse Mare to an Orphaned Foal

Feature RSS Feed

March 31, 2016

Mare and FoalThe arrival of a foal is always an exciting time regardless of whether you have a large breeding farm or just one mare to foal out. What happens when an emergency arises and you find yourself with a very young orphan foal that needs milk? Problems that may arise include: the mare dies during or soon after foaling, the mare colics or has other health issues which require emergency intervention, the mare rejects the foal, and/or the mare does not produce enough milk or “dries up.” There is always the option of bottle feeding these foals but this is a very time consuming process and the foal could tend to be more socialized towards humans than horses. These unfortunate circumstances are the perfect time to consider a nurse mare who can be brought in to adopt and raise the orphaned foal.

Featured Blog: What Can Cause a Mare to Lose Her Pregnancy?

What Can Cause a Mare_Ascending placentitis originating at the cervical star Mares 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.

Featured Question

Can you get a mare in foal with semen less than 30% progressive?

Yes. Even though 30% is the recommended cut-off for commercially acceptable frozen-thawed semen, just like with fresh or cooled semen, some stallions can obtain acceptable fertility with semen that has motility below 30% provided there are enough functionally viable sperm in the insemination dose. Post-thaw motility is a good indicator of how well the sperm have withstood the stresses of being frozen and thawed and one should be cautious about using frozen semen with less than acceptable post-thaw motility. A significant reduction in progressive motility after thawing is indicative of sperm damage and there may even be sub-lethal damage to sperm that remain motile after thawing that would reduce fertility. And remember that the assessment of post-thaw motility can vary significantly between laboratories.
