USMMA Marchador Quarterly – Winter Edition

Enjoy this winter edition of the USMMA Journal!   For future issues:

  • Please submit your MM photos!
  • Please submit stories about your MMs!
  • Please send us questions for our resident vet, Dr. Tia Nelson or any of your USMMA board members!

We hope to publish quarterly:   January, April, July and October.

One of the things we hope to do with this publication is to feature the diversification of how the Marchador is used with real life examples.  This Winter we are featuring stories of the Mangalarga Marchador told by others! 


  • SPRING: March 30
  • SUMMER-June 30:    
  • FALL: September 30 and
  • WINTER: December 31.

To send in submissions, email the Journal Editor – Tresa,

Happy Trails,

Tresa Smith, Owner, Breeder and Importer – Lazy T and Lynn Kelley, Owner, Breeder and Importer – Summerwind

October 28 Clinic – Human Horse Sensing

Held at Silver Stables, 3121 W Desert Hills Dr.  Phoenix, AZ.  8:30 a.m to 3:30 p.m.   Lunch will be included.

All breeds are welcome!

The cost is $100 per participant with or without horse.   Pay via PayPal to

The event at Silver Stables is the first of the series Human Horse Sensing Horsemanship, a new way to being with horses.
In our time and age the horse has become a partner more than an instrument for work, but still lacks of freedom of movement, social interactions, and ability to freely express himself. In light of this reality, it is very apparent that the quality in the human and horse communication, and consequently their relationship is questionable. In response to this reality we created Human Horse Sensing, a way to relate that works with any individual, at any age, without the need of training. The method is designed to create horsemanship as a dynamic, and controllable process that efficiently supports human and horse in their interaction. Human Horse Sensing can be taught, and learned by clinics, or online course, and can support the communication, needed for all equestrian activities.
The USMMA benefits from this clinic being hosted by Summerwind Marchadors and Silver Stables as the clinician Alessandra Deerinck has offered to donate 10% of the proceeds to our association! Great fund raiser! Thank you all!

“In a time and age when most of us keep horses by choice, not by need, Human Horse Sensing is dedicated to teaching people who want to interact with them in a way that horses would choose to participate freely.   Let us take you deeper than traditional training, and show you how to understand, learn, and play from your horse’s perspective.” — Alessandra Deerinck

MM DNA Testing!

Summerwind Marchadors has the DNA  results for most of our Marchadors!   Fascinating!

b698fa_092bb8575c9a8b9d873506d8ca8da0a0Our DNA – genetic analysis was done  by Heather Holl, of Etalon Diagnostics Lab, CA who was looking for more samples for her study to develop a new genetic test to prove parentage.   Along with contributing to her research project, we got a full report on each horse.  It is exciting!

From a breeding standpoint, we can report now on many of our Marchadors characteristics!

Of particular interest to us is the “gait” gene DMRT3.   This is one of the genes identified that is involved with horses that gait laterally. However, it does not perfectly describe horses that possess a diagonal gait.   Indeed some of best horses do not display this gene.  Additionally, this DMRT3 gene has been found in trotting horse breeds.   So, current thinking is that perhaps this gene describes a horse that would rather stay in gait instead of transitioning up into canter, which is why now, it is sometimes described as “loss of canter”.

195b6c9d6dc180f25150928a54e59a6cBecause DMRT3 is not “THE gait gene” as so many describe it, Summerwind Marchadors is also supporting the Equine Genetics Research lab at UF, Gainesville.   This project is headed by Dr. Laura Patterson Rosa,  testing for gait gene secrets in OUR Marchador breed.  For more information or to contribute to their research,  follow this link:

We will start adding this information to our horse’s pages on the website, but here is the summary report on John’s gelding Artemis do Summerwind, as an example of the information we have now on every horse.

Genetic Profile Test Results Horse: Artemis Do Summerwind Owner: John Kelley

Disease: NONE

Color:  Aa, ee, G/n, nd1/nd2, W20/n

Traits:  GG (curiousity), TT (Endurance Type), DMRT3/DMRT3

Disease: Artemis Do Summerwind has not tested positive for any recessive disease alleles on this panel.

A new discovery test for West Nile indicates he may be more susceptible to West Nile.  A new discovery test for a Subfertility gene indicates 2 alleles are present.  In male horses, 4 alleles present may mean they have lower rates of foal production.

Coat Color: Artemis Do Summerwind has two Red alleles and no Black, indicating his base coat color appears Red. One copy of the Dominant Agouti allele was detected; invisible on a Red base (it pushes/restricts Black out to points; legs, ear tips, etc. appearing Bay). One Grey allele was detected which may result in greying of the entire coat (possibly appearing White at maturity). One Dominant White 20 allele was also detected which may result in White markings.

His DNA also tested on a discovery platform to indicate he is heterozygous for non-Dun pimitive markings and there may pass it 50% to his offspring.

As a result of the allele count in each of the following, he has a minimum 100% chance of passing Red and 50% Dominant Agouti and 50% Grey and/or Dominant White 20 to any offspring.

His DNA also tested on a discovery platform to indicate he is heterozygous for non-Dun pimitive markings and there may pass it 50% to his offspring.

Traits:  Artemis testing has indicated the presence of 2 DMRT3 alleles and he may therefore, pass it 100% to his offspring.  2 Curiosity genes (100%) were detected.  He is likely more curious than vigilant.   2 Endurance alleles (100%) were detected; he is likely more distance than Sprint.
