Description
Why are there so many horse breeds in the world?
What are the different breeds of horses and what differentiates them?
When did selective breeding for horses first begin?
Dr. Chris Mortensen who is an equine science researcher and educator with over 20 years of experience tells us. He starts
off this episode discussing the mysterious disappearance of wild horses from the Americas 10,000 years ago.
We jump into how horses made a comeback in the 1500s with the arrival of the Spanish and other Europeans to the Americas. Thus, we start with a journey into the story of a horse found in Haiti, dating back to the Spanish community of Castile in May 1572. It was four hundred years later, archaeologists uncover parts of his remains, revealing his long-forgotten story.
Exploring Horse Breeds
We transition in chatting about the Importance of horse breeds in understanding behavior, capabilities, and health. Then a brief discussion on breed-specific characteristics and how they influence what activities horses are suitable for.
This is followed with a discussion on breed registries, their rules, and the impact on a horse's value. To include an overview of breed regulations, such as those of Thoroughbreds (Jockey Club) and the American Quarter Horse Association.
Understanding Horse Breeds
The definition of a horse breed is a group with a common origin and distinguishable characteristics passed on to their offspring. Breed registries are the governing body of most breeds by setting
rules and maintaining stud books.
There are a variety of horse breeds, and they have important breed-specific characteristics. We explain the categories of horse
breeds: light breeds (riding types), heavy breeds (draft horses), and pony breeds. Then provide an explanation of the terms hot-blooded, warm-blooded, and cold-blooded in relation to horse temperaments.
Genetic Insights into Horse Breeds
We are now able to trace horse lineages through mitochondrial DNA, revealing historical insights. Maternal lineages show us the horse’s roots with the slow mutation rate of mitochondrial DNA.
This is important as genetics helps us under the many genetic disorders we see in many horse breeds. Genetics also are important of breeding selection. Genetic diseases like hyperkalemic periodic paralysis (HYPP) and severe
combined immunodeficiency are a result of heavily selected breeding.
The Evolution of Horse Breeding
We briefly discuss the historical overview of horse breeding: from
domestication to the Middle Ages, Renaissance, and beyond. Emergence of breed registries, standards, and specialization during the industrial revolution. Then the explosion of horse breeding in the 1800s and 1900s, leading to the
diverse breeds we see today.
The Journey of the Colonial Caribbean Horse
(Continued):
We pick back up the story of the discovery of a Colonial Caribbean horse in Haiti in the 1980s. Extraction of DNA
and analysis linked it to the Chincoteague Pony, and the Caspian horse.
The Caspian horse, thought to be the oldest domesticated breed, with a significant role in the development of modern horse breeds. Efforts to conserve the Caspian horse as a representation of ancient equine history.
Conclusion
A glimpse into the vast history and diversity of horse breeds, with more detailed explorations to come in future episodes.
Stay tuned for upcoming episodes where Dr. Chris Mortensen delves into specific breeds, their characteristics, and the fascinating stories behind them.
