Official State Animal of Missouri
Missouri designated the Missouri mule as the official state animal in 1995 (Missouri also recognizes a state horse). South Carolina also adopted the mule as a state symbol. All State Horses
Mules were introduced to Missouri in the 1820's and quickly became popular with farmers and settlers because of their hardy nature. Missouri mules pulled pioneer wagons in the 19th century and played an important role in moving troops and supplies in World Wars I and II. For decades Missouri was the nation's primary mule producer.
What is a Mule?
Mules are hybrids, the offspring of a mare (female horse) and a jack (male donkey). The reverse (the offspring of a male horse and a female donkey) is called a hinny. Mules and hinnies are almost always sterile because the two species have a different number of chromosomes (donkeys have 62 chromosomes, horses have 64).
Types of Mules
Today mules are usually divided into two types: “draft mules” and “saddle mules” (there used to be more categories like “sugar mule,” “cotton mule,” etc., but these names disappeared after the early part of the 20th century). Most people now identify a mule by the mother, i.e: “Quarter horse mule,” "Tennessee Walking mule,” “Percheron mule,” etc.
