Just this one night, after checking each night for two weeks, the exhausted high school teacher did not make the quarter-mile walk to check on her pregnant mare. Of course, this was the night she foaled. They were so vital. But their vitality quickly deteriorated as diarrhea set in, and worsened. At three days old, unable to nurse, they were on their way to New Bolton Center.
Seeing Double: Handling Equine Twins
Twins - Goulburn Valley Equine Hospital
We have known three things about twins for a long time. Firstly twins are repeatable within the same mare, secondly twinning rate varies according to breed and thirdly, the more fertile the stallion the more twins he is expected to achieve. Twins are avoidable and should not occur on well managed breeding farms. Clients understand this and are demanding the most sophisticated management programs available. Presented below are the management techniques in use at the Goulburn Valley Equine Hospital. The hospital is a major referral centre and each year is expected to handle multiple referral cases of twin pregnancy that are diagnosed after cessation of the mobility phase.
Identical Twins Have Identical Twin Horses
Also see Abortion in Horses. Twin pregnancy is the most common noninfectious cause of abortion in mares. In most cases, uterine capacity and subsequent placentation are inadequate to support two fetuses to term. Premonitory clinical signs of impending abortion may be only premature mammary gland development. Fetal membranes should always be examined for large avillous areas typically located between the twin conceptuses.
The horse Equus ferus caballus   is one of two extant subspecies of Equus ferus. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae. Humans began domesticating horses around BC, and their domestication is believed to have been widespread by BC. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as feral horses.
