What Is Dystocia in Horses?

Dystocia simply means difficulty foaling, occurring either in the first or second stage of parturition. During a normal foaling the mare will become restless as stage one starts, her contractions begin and the fetus changes position so that its head and forelimbs are in the birth canal.

What causes dystocia in horses?

Most causes of dystocia in the mare are due to abnormal presentation, position, or posture. A dead or compromised fetus often is not properly positioned in the pelvic canal. Dystocia due to fetal–maternal disproportion or primary uterine inertia is rare in mares.

What can cause dystocia?

Dystocia of fetal origin is generally caused by fetomaternal disproportion (large fetus), fetal abnormalities, or abnormal presentation, position, or posture.

What happens in the first stage of labor?

During the 1st stage of labour, contractions make your cervix gradually open (dilate). This is usually the longest stage of labour. At the start of labour, your cervix starts to soften so it can open. This is called the latent phase and you may feel irregular contractions.

What are the normal position presentation and posture for a foal to be born?

The foal lies with an anterior longitudinal presentation in a dorsosacral position. The front legs are extended and one forelimb is slightly forward of the other. The foal’s head rests on its knees.

What are the 3 types of dystocia?

  • Frank breech: The fetal hips are flexed, and the knees extended (pike position).
  • Complete breech: The fetus seems to be sitting with hips and knees flexed.
  • Single or double footling presentation: One or both legs are completely extended and present before the buttocks.

How do you prevent dystocia?

Prevention of dystocia includes encouraging the use of trained labor support companions, deferring hospital admission until the active phase of labor when possible, avoiding elective labor induction before 41 weeks’ gestation, and using epidural analgesia judiciously.

What are the symptoms of dystocia?

  • Strong abdominal contractions for greater than 30 minutes with no delivery of a puppy.
  • Weak straining for greater than two hours with no delivery of puppy.
  • Greater than four hours between delivery of puppies.
  • A retained pup at the vulva.

How is dystocia diagnosed?

Thus, the traditional criteria to diagnose active-phase arrest are cervical dilatation of at least 4 cm, cervical changes of < 1 cm in 2 hours, and a uterine contraction pattern of >200 Montevideo units. These findings are also a common indication for cesarean delivery.

What are the types of dystocia?

There are several types: Frank breech: The fetal hips are flexed, and the knees extended (pike position). Complete breech: The fetus seems to be sitting with hips and knees flexed. Single or double footling presentation: One or both legs are completely extended and present before the buttocks.

Is dystocia a diagnosis?

The diagnosis of dystocia is especially common in nulliparous women and constitutes the single largest indication for primary cesarean delivery.

What causes a foal to be stillborn?

Results: Overall, a cause of fetal loss was established for 72% of the examined cases. Most cases (62%) were lost due to a non-infectious cause, of which obstruction of the feto-placental blood circulation due to severe torsion of the umbilical cord was most prevalent.

What’s the longest a horse can be pregnant?

When are they due to foal? The ‘average’ gestation for horses is 340 days, but ‘normal’ gestation can be as short as 320 days and as long as 370 days.

How many times can a mare foal?

Can a horse absorb a foal?

Up to 30% of mares that conceive will lose the fetus before foaling. Most of these losses occur in the first 35 days of pregnancy and the embryo is resorbed, after which the mare may come back into heat at a longer interval after the last estrus. There are procedures that should be followed when a mare aborts.

Can you give a horse an abortion?

Abortion is when a pregnancy is terminated prematurely. An abortion can occur spontaneously, or it can be medically induced in cases of serious complications, such as twinning, or if the mare’s health is being compromised by the pregnancy.

How early can a foal be born and survive?

Foals born before 320 days are considered premature and require special veterinary care if they are to survive. Foals born before 305 days do not survive. Long gestations of up to a year appear to pose no problem, the foal will be born when it is time.

How long does a mare drip milk before foaling?

Around four to six weeks prior to foaling, your mare’s udder will begin to enlarge and produce milk, in preparation for the arrival of her newborn foal. As her foaling date approaches, the pressure building up within her udder may result in minor milk dripping, which is normal upon or immediately preceding labour.

Can a mare have milk and not be in foal?

Some mares lactate despite not being pregnant and not nursing a foal. There may be hormonal reasons for this, but the scientific explanation remains unclear. There is some speculation about whether mares that have Cushing’s disease (PPID) might produce hormones that cause milk production.

Is horse milk edible?

What can you give a mare to produce more milk?

Mares need energy and high-quality protein for milk production (14% crude protein grain mix). Generally an increase in grain volume will supply more energy. 2. Low lactating mares consuming fescue pasture or hay may benefit from a veterinary-prescribed paste marketed as Equi-tox to increase milk production.

How long does it take for a mare to dry up after weaning?

Following weaning, the mares should be turned out in an area where they can be freely exercised, and their grain ration should be decreased for seven to 10 days to facilitate drying up and to prevent weight gain, as they are no longer producing milk for their foal. Thomas R.

How much milk can a horse produce in a day?

Lactating mares produce approximately 2-4% of their body weight in milk each day. That means that a 1,200-lb (545-kg) mare will produce 24-48 lb (11-22 kg) of milk per day, equivalent to 3-6 gallons (11-22 liters).
