Yes, much like chestnut on the inner legs, ergots can and will grow back over time.
Its sort of like a chestnut, it grows on the back of the fetlock joint. Some horses have them short, most feathered horse might have them a little longer, you can pull them off like you can a chestnut.
Ergot. It is very similar to the chestnuts on a horses leg, and they have no nerve endings. they can be cut off and the horse will not feel it.
Ergot
Ergot can grow on rye and other grains as a result of infestation. Claviceps purpea, or Ergot, can get into food made with grain products that have been infected. Typically, it grows in temperatures of 18-30 °C (64.4-86 ºF) temperatures above 37 ºC (98.6 ºF) causes rapid germination, or the sprouting of fungi. If you know where your grain products are coming from you should be fine from the Ergot.
All horses have a ergot on the rear of their fetlock.I include this link as you don't state where on the fetlock. (see link)
Yes, horse hair grows back after it is cut. Horses, like many mammals, have hair follicles that continuously produce new hair to replace the old or damaged ones. However, the rate of growth and the quality of the new hair can vary depending on factors such as the horse's health and genetics.
Full grown horses and ponies can be from 2ft to 7ft tall at their back, but usually they're somewhere in between.
I think the explanation is: Ergot is a fungus the grows on grains, so maybe if you ate spoiled grain it could have had ergot on it?
Ergot typically infects grasses such as Paspalum dilatatum through its reproductive structures called sclerotia, which resemble grains of wheat or rye. These sclerotia contain alkaloids that can be toxic to animals and humans if ingested. Therefore, it is important to be cautious when dealing with grasses known to be susceptible to ergot infection.
