In this situation, instead of the allanotoic sac being ruptured during the foaling process typically by the foals feet with the subsequent release of the allantoic fluid (the waters breaking) and the passage of the foal within the amniotic sac, the entire (or a major portion of the) allantoic sac is presented externally in an unruptured state with the foal still fully enclosed. Maiden mares are particularly notorious for little or no development until in some cases, after foaling. [1]A variety of occurrences are then possible, including separation of the placenta from the uterine lining, reduction of oxygen and nutrient transfer to the fetus, and fetal deathin uteroor abortion of a live, premature and/or compromised fetus. Researchers have developed several commercial foal prediction tests that measure calcium levels, pH levels or electrolyte levels in mammary secretions. .

Evaluation of the placenta following foaling can be useful to determine if the the placentitis was of an ascending form, which would suggest external causative pathogenic source, or if the inflammation is solely limited to the uterine horn region, which would suggest that the source originated from within the uterus. These two combined evaluations determine with variable accuracy the presence (or absence) of an organism, and whether an organism, if present, is pathogenic in nature. Unlike in some other species notably the bovine Dexamethasone at a dose of up to 100 mg IM during late pregnancy did not cause abortion or delivery of a premature foal, but was shown to accelerate fetal maturity and shorted the gestational duration significantly. Mammary gland development will be much more pronounced in mares that have previously had foals than in maiden mares. KTFMC AGM Newsletter 66;3:1-2. In most cases, udder enlargement begins about 4-6 weeks prior to the predicted foaling date, or at about 280 days.

Another important aspect of the antibiotic is that not all antibiotics have an ability to penetrate reproductive tissues and access allantoic/amniotic fluids to achieve minimum inhibitory concentrations (MIC). . In the older maiden mare, treatment for endometritis is ideally performed before ovulation. Handlers should be ready to assist if it goes much longer than an hour.

In general, the gestation length will be predicated upon individual factors rather than age, with overall health and cycling history contributing to the mix. While its critical to remember that every mare is different, each mare usually has a consistent foaling pattern, showing similar signs on similar timelines from year to year. The mare shows any signs of pain or colic post foaling. For example Sulfa drugs can create gastro-intestinal problems in the mare, while Gentamicin remains longer in the fetal compartment than in the mares circulatory levels and prolonged use can damage the foals kidneys. The previous year, with the placenta previa, the foal had been presented dead despite it being an attended foaling with opening of the placenta and rapid assisted delivery performed. 42. 2018.
