Equine Speed Gene Traced to One Founding Mare
Here’s an interesting story about some additional findings on equine genetics and the history of the racehorse:
“Speed Gene Traced to One Founder
Researchers track a racehorse “speed gene” back to a single mare in the United Kingdom.
By Edyta Zielinska | January 26, 2012
A gene linked to speed in today’s Thoroughbred horses was tracked back to a British mare that lived roughly 300 years ago, according to a study published in Nature Communications Tuesday (January 24).
The gene, a variant of myostatin, the factor involved in muscle mass development in many species, was shown to predict the speed and stamina of a horse. Two copies of the C-type variant, for example, is likely to result in a horse that runs fast over short distances, ideal for the sprint races that are common today. The other variant, the type T, is better suited for stamina, allowing horses to run fast for long distances.
Researchers looked at the genetics and pedigree of 593 horses, dead and alive, and tracked the C-type variant to a single mare. While horses carrying the C-type variant were still rare in the 18th and 19th centuries, they were widely propagated in the 1950s, ’60s, and ’70s by breeding two celebrated father-son stallions, Nearctic and Northern Dancer.”
EHV-1 Equine Herpes Virus Outbreak Update
Reported this week in California: Three new cases of EHV – 1 (Equine Herpes Virus) were reported and confirmed this week, on January 13th, at a California barn in San Juan Capistrano. The infection is not thought to be show related and the barn is under quarantine. A fourth case is suspected (but not confirmed by this source) at a second location in Raleigh at a School of Veterinary Medicine. Folks are advised to watch their horses carefully for any possible symptoms and be aware of contact with other horses and barns. It is not advisable to admit any horses of unknown previous origin into your facility or to have contact with outside animals (i.e. avoid contact with other unfamiliar horses on trail rides, at commuter barns, etc.) Below you’ll find a recap of a previous post with information on EHV-1. As with all health alerts, if you are unsure or have questions, be sure to contact your veterinarian.
- EHV-1 Outbreak Virus Alert
The least you need to know:
- EHV 1 or Equine Herpes Virus is a long existing viral infection that, when an outbreak occurs is very contagious and easily spread.
- Spread by a variety of means: Airborn, close contact, via handler’s clothing, shared stalls/feed/grounds
- It it not known to infect humans
- It can cause multiple forms of disease in horses (4 types) but respiratory is the most common
- Symptoms: High Fever, Lethargy, Runny Nose (clear), Difficulty Standing, Neurological Effects
- Many horses develop respiratory symptoms and eventually recover
- When the disease crossed into the central nervous system the results are disastrous and deadly
- There is no known vaccine against EHV-1 and only supportive care treatment for those infected
- Current recommendation is to keep horses home, move only in emergency and avoid transport from one facility to another
- If you have been to a barn today DO NOT go to another as you may transmit the virus on your person.
The bottom line here is that this disease is a rapid spread and rapid fizzle virus with a high morbidity and mortality rate. Evaluate your plans carefully for where and when you are traveling and working with your horse.

Tsunami – Yikes!
This is just an update from DreamFriesians where one of our favorite boys is currently attending a clinic with David Hunt in Watsonville right in the middle of the wave tsunami aftermath. We are on the California coast and woke to road closures and evacuations along the coast from Half Moon Bay down to Montery Bay. Expected at around 8am were supposed 2-3 foot waves and surge which did not materialize (in our area of Santa Cruz and Watsonville). However, around 9:15am we began experiencing some serious surges in the ocean levels (tide going completely out and then returning within minutes). These ocean surges are causing boat docks to break free along with their boats, floating free in the surge and, unfortunately smashing into each other and other structures. Although we haven’t seen any significant waves cresting onto land or houses (and certainly nothing like Hawaii or poor Japan) we continue to be on high alert.

Anyone having first-hand photos or advice on the coast or our horses (and preparation for them in this type of situation) is welcome to comment!
