Domestic Horse

Domestic horses occur worldwide and include numerous breeds developed for riding, traction, racing, herding, agriculture, and companionship. They are large, long-legged grazing mammals with a single hoof on each foot and a body specialized for sustained movement over open ground. Horses are strongly social and naturally form groups with recognizable dominance relationships. They communicate through posture, facial expression, touch, scent, and varied vocalizations.

Horses are herbivores that graze grasses and herbs and commonly receive hay or other plant-based feed under human care. Their digestive system permits almost continuous feeding on fibrous vegetation. Females usually produce a single foal after gestation lasting approximately eleven months, while twins are uncommon. Foals are well developed at birth, stand within a short period, and follow their mothers. Maternal nursing and protection continue for several months before weaning. (Animal Diversity Web)
