Does anyone know why a mini was born still in the sack, with teeth and hoof hair???? We thought she was early and hadn't locked mom up yet. I still think it was early, but with teeth??? The hair on the hooves was about 1 1/2 feet long and blonde like her lower legs. Her hooves looked a lot shorter than birth sized hooves. Can anyone help me figure this out?

Yes, they were in a fescue pasture, and we thought we still had time to put them up. We fed broham hay all winter. She had not been put in the barn yet. What caused the hair growth on the hooves? That shocked us. We have never seen anything like that before. We have only been raising minis for 5 years. We thought she was only in her 8th month.

Fescue poisoning causes very odd things to happen with the foals. Especially if the mare is small. Was the hair really 1.5 feet??? I thought that was a typo and you meant inches?? That would be very abnormal. Do you have pictures?? Were there any other deformities?

also this article says they can have abnormal growth given the gestation in months which is probably what happened to your foal. Im so sorry!! If at all possible its best not to let mares in foal graze on fescue. I think the minis cant handle it as well as big horses

Prolonged Gestation

The normal gestation length in horses is approximately 11 months. However, mares that graze on endophyte-infected fescuecan have pregnancies that last up to 13 months or more. This is a problem because the fetus continues to grow during the extra timewhich can result in dytocia (difficult birth). The foals born after prolonged gestation may appear to be immature despite their extra fetal development.

The characteristics of a foal born after prolonged gestation include a large frame size and poorly developed muscles. Also, some foals may have overgrown hooves, while others may have premature and irregular eruption of baby teeth. These foals can also exhibit hyperthyroidism, resulting in poor suckling reflex, incoordination, and low body temperature.

Fescue Toxicosis: Effects on Foals

The newborn foal can suffer greatly from the effects of fescue toxicosis. The range of fetal deaths in the last third of pregnacy for herds affected by fescue toxicity varies from 0 to100%.

Generalized symptoms associated with foals born to mares grazing on endophyte-infected fecsue include

* prolonged gestation

* dystocia

* abnormal foal maturation

* weakness

* starvation (due to dam's agalactia)
