Few things in nature are more inspiring than new foals frolicking around their mothers on a crisp spring morning. The fact that a foal can be up and running within a few short hours after birth is but one in a long series of miracles. Conception is miraculous in itself. Development in utero, or in the womb, begins with the formation of all of the organ systems and is followed by their maturation. During the entire process, the foal is completely dependent on the mother’s blood supply for eating, breathing, and eliminating metabolic waste products.
