| WHY
“V” FACTOR
Ever
since the dawn of the “horse age”, there have been gaited
horses. Research into the ancient progenitors of modern
gaited stock show that the earliest “pacing” horses appeared
or at least were recorded around the Mediterranean about
4500 years B.C. From this stock stem most if not all gaited
horses in the world. They were distributed to the far reaches
of the globe by the Phoenicians, Goths, Visigoths, Celts
and many other tribes of people who traveled, traded and
plundered the ancient world.
Everywhere
the trade routes or conquering hordes went, pockets of gaited
horse sprang forth where before had been only trot based
horse types if indeed horses existed in those realms. Ever
after that for many
centuries gaited horses existed as yet today they do in
many isolated pockets around the globe from China, Russia,
the Ukraine, Tibet, Africa, Morocco, Spain and Europe.
Finally
the descendents of these early pioneers of gait migrated
to North America (as well as South
America) and the Caribbean. From those early imports spring
our modern gaited breeds.
The
largest percentage of early stock in America were gaited
whether they were considered Thoroughbred,
Standardbred, Morgan etc. The ratio of gaited to non-gaited
in the early centuries of this nation were
approximately 14 gaited to 1 non-gaited. English Thoroughbred
stallions were brought over to upgrade
the stocks and from those crosses spring all American breeds
with a few other crosses coming by way of
Spanish, French and Dutch horses but those were predominantly
of the light draft type.
The
earlier Saddlebreds were largely Narragansett Pacers and
gaited Thoroughbreds. Later Morgan,
Hackney, Standardbred and Canadian Pacer were added to the
meld until the American Saddlehorse ( not the same as Saddlebred
as we know it) was developed.
Those
horses were utilitarian, versatile animals with placid dispositions,
good work ethic and willing
natures. They were used as saddle mounts but also to plant
crops, pull wagons, work cattle and perform
other ranch work. The Saddlehorse pulled wagons cleared
the land and became stylish roadsters once
road systems allowed for carriage travel. A portion of them
became in later days, the beginning of the Show Horse in
America. This stock eventually evolved into what we know
today as the American Saddlebred.
Much
of the old Saddlehorse stock, however, also branched off
to become part the foundation for the
Tennessee Walking Horse, the Kentucky and Rocky Moutain
Horses, the Virginia Highlander and many other small obscure
gaited types around the country. Keep in mind there was
only so many horses or horse types in the country from which
to develop specific strains so all American breeds are related
to one degree or another.
For
our purpose it was this fine old Saddlehorse stock that
was at the very tap roots and foundation for the
original type of Missouri Foxtrotter. These horses pioneered
the Ozarks where they were used to till
crops, pull cotton wagons to the gins, work cattle, pull
the family buggy, provide transport for the mail
carriers, doctors, judges etc. But most importantly they
became the solid family, utility horse of the
Ozarks. The horse all the family members could use and enjoy.
They were sure footed, athletic, capable
horses with natural gaits. Many of these early horses preferred
to foxtrot and the foxtrot gait proved to be the most sure
footed and useable gait in the rugged Ozark hills. It was
a working gait that allowed for the utmost athletic ability,
sure footedness, and a steady, smooth ride even in the hills.
Toward
the end of the 1800’s a new concept was developed among
horse breeders whereby the recording
horses in order to track pedigrees evolved into the development
of breed registries. This allowed breeders to be more efficient
at the art of selective breeding. America entered the world
of Registered breeds with more than a dozen registries forming
within a span of a few decades. The Missouri Foxtrotter
breed was established only 65 years after the Standardbred
became the first registered breed in America!
Where
gaited horses were concerned this phenomenon of registries
created a situation no one had considered and for the most
part do not consider to this very day. By closing ranks
and limiting outside influence to the type, there was no
way to control the amount of pace in any of the gaited breeds.
Before breed registries if a bloodline got to pacy, breeders
simply crossed out to more trot. Within breed registries
this was not always possible.
For
those gaited breeds that rely upon the more lateral gaits
this process was to alter the balance of
the pace to trot ratios very quickly. By the late 1900’s
many of the gaited strains were being over
taken by pace. Horses that were bred supposedly to rack
were hard pacing, those bred to running walk were pacing.
More and more frequently horses bred for one gait became
disappointments when they were born pacing.
The
same phenomenon began to appear in the Standardbred community
where they do not recognize
intermediate gaits. Horses are bred to pace or trot. Anything
in between is not given attention.
In the
late 1900’s a study was conducted whereby a number of pacing
Standardbred mares were bred to
trotting stallions. As a result the large majority of foals
born paced. The same number of trotting mares
were bred to trotting stallions… again a substantial percentage
of the offspring paced. BUT, when pacing
mares were taken to pacing stallions, 100% of the offspring
paced.
From
this study it was deduced that pace was stronger than trot.
The study also illustrated that pace tends to quantitate
within a bloodline until it becomes the overwhelmingly stronger
gait.
Because
the study did not recognize those horses that fell between
pace and trot…those that performed
intermediate gaits, we cannot be 100% certain what the balance
needs to be for any particular gait in order that one particular
gait could be consistently produced.
Dr.
Gus Cothran, of Texas A & M, participated in a study
whereby geneticists were able to identify the
difference between pace and trot at the molecular level.
This was the first time science could
substantiate a genetic difference between the two gaits.
But again intermediate gaits were not examined.
The tests were looking simply for the difference between
pace and trot. The results show there is as
much difference between pace and trot as there would be
between totally unrelated horse breeds. That is a very substantial
difference.
In private
research among gaited horses it was found that horses that
fell within a certain ratio of pace
to trot consistently performed the same gaits…or preferred
to perform the same gaits. This was the
first time pace ratios were considered in the intermediate
gaits. Hundreds of horses were examined
and then their pedigrees studied.
The
result of this study was the realization that in order to
consistently produce a particular gait the
pace/trot ratios in the horse needs to fall within certain
ranges with a tolerance varying between the
gaits. The more refined that ratio becomes the more limited
numbers of gaits a horse performs.
Since
most of the gaited breeds are suffering with the run away
pace influence it became paramount to
identify the cause for pace taking over these breeds in
order to prevent the same thing from occurring
among the Missouri Foxtrotting Horse.
Pedigrees
were analyzed and traced back to their full pace progenitors
in order to get an idea as to how the pace modifies the
trot. In order to have an intermediate gait a horse must
have some pace. The key
appears to lie in the balance of the trot/pace ratio as
to which dictates to what gait that horse will
naturally gravitate.
From
this study it became possible to give a mathematical identity
to the various balances. These
numbers represent percentages of pace however in order to
make this type of factoring practical for the
average breeder to benefit, it had to be simplified.
In the
original formative years of the MFTHBA all horses entering
the breed were inspected to see if
they would foxtrot under saddle. The flaw to this is that
some gifted riders could make a Grizzly bear
foxtrot while some less adept riders may prevent a natural
foxtrotting horse from functioning properly.
This also did not consistently limit or preserve a specific
balance of pace and trot.
The
early horses reproduced far more consistently however, than
later generations. Had breeding been
consistent and cognizant of the pace/trot ratios, the breed
should have been settling and standardizing for
gait. Instead of standardizing, the horses began to deviate
more and more from the original goal.
Tracing
back on the pedigrees of these generations of horses it
became evident that the heavy influx of
Tennessee Walking Horse blood during the 1970’s and 80’s
likely over balanced the pace ratio of the group. This gave
the pace opportunity to quantitate….( get stronger) more
rapidly. Even though the horses
themselves gaited, they carried more pace genes from a closer
source than was present in the old
Saddlehorses.
Because
pace is already stronger than trot, as soon as the pace
influence reached a certain point, there was not enough
trot influence in some bloodlines to consistently modify
that pace. The result was more
horses began to running walk than to foxtrot naturally.
Then the next generations or certain
bloodlines began to rack, stepping pace and then finally
pace. Some bloodlines sprang directly from
running walk to hard pace.
This
same thing occurred in the Tennessee Walking Horse, the
Paso Fino, the Peruvian Paso, the
Saddlebred, the Mountain Horse breeds etc. Because the trot
base was not well preserved the pace took over.
The
process was delayed in the Missouri Foxtrotter primarily
because the foxtrot is the most diagonal of
all the intermediate gaits and therefore was initially the
strongest in trot ratio…farthest from pace. In
specific groups that were closed and standardized to the
desired ratios of pace to trot, the horses indeed
began to breed true. The horses were uniformly born foxtrotting
to the exclusion of any lateral gaits.
Most
of these horses foxtrot and running walk because the running
walk is the same gait as a flat walk. The flat walk and
running walk are both 50/50 gaits. It would be very difficult
to breed all running walk out
of a line and yet preserve a good flat foot walk. It is
highly possible to breed out the flat walk AND
the running walk and yet preserve a natural foxtrot.
From
the early years of the Foxtrotter Registry the show ring
was the focus point of the breed. In the
1980’s however, the type of foxtrot awarded first prize
in that show ring began to change.
The
original Foxtrotters were known for capping their tracks
or barely stepped over them when they
foxtrotted. This is how the breed and the gait got it’s
very name. However that type of gait is not as
fast as a big lick stride. For show ring purposes the cross
with Tennessee Walking Horse blood tended to
lengthen the stride and thus add speed to the gait. Those
first crosses were quite impressive, however the
more crosses that were made the closer to pace the group
drifted until the style of foxtrot began to
evolve away from the true rhythm of the original type. The
horses no longer capped their tracks which also
diminished the surefootedness of the breed.
Over
the course of several decades the strides became longer
and longer until conformation also began to
change. The athletic ability of the very long strided horses
was not nearly so handy and versatile as the
more compact original stocks.
Eventually
the pace reared it’s ugly head until more and more pace
became the outcome of matings between horses that could
foxtrot. Just as in the earlier Standardbred study, the
foxtrotting horses were
producing pacing offspring or offspring that preferred a
more lateral intermediate gait.
Some
of these horses could manually be squared up enough to foxtrot,
but the fact remained a foxtrot was not their natural gait
of choice.
The
breed went from a base of 80% Saddlehorse/Morgan influence
to what today is nearly 90% TWH influence. That is to say
it is very difficult or nearly impossible to find a registered
Missouri Foxtrotter
that does not have Tennessee Walking Horse in it’s pedigreed.
Indeed today many of the registered blue
papered Missouri Foxtrotters are actually 100% Tennessee
Walking Horse by blood. Many, many more are 7/8 to ¾
Walker which is the exact opposite of the original foundation
stocks that created the original
breed of Missouri Foxtrotting Horses.
Because
we know that pace is stronger than trot and we know that
the Tennessee Walking Horse represents more pace from closer
progenitor, the logical way to preserve a strong trot base
is to limit the influence of the TWH on the breeding nucleus
of the breed.
This
was not likely to occur breed wide because to do this would
also be to limit the big lick stride so
desired in the show ring. The desire is not to remove all
TWH blood from the breeding core, but rather to
take advantage of some of it’s attributes such as longer
stride ( within reason) and larger bone and
joints, while not allowing it to totally consume the original
Saddlehorse/Morgan base or overpower the
strong trot base those two types represent
The
desire to preserve the original style of Missouri Foxtrotter,
however, was left to the silent majority
of the breed as so often is the case. The large majority
of horses never go to a show ring, nor need
they! The show horses are not superior in any way to the
original style of horse when it comes to function
and ability. Far the reverse. Yet the public eye focuses
on the “Champions” of the show ring and rarely
get to see the quietly working, solid, more foundation type
Missouri Foxtrotting horse.
To overcome
the imbalance of pace to trot and preserve the original
style horse many people were talking
about splitting away from the mother registry. They were
dissatisfied at what appeared to be a
disproportionate amount of attention and funding spent on
shows and show horses than was meted out to those who had
no interest in showing. The large majority of horses that
don’t go to the show ring do not go there because they are
inferior, but rather because not many people enjoy the politics
and pressures that come along with the competitions of the
show ring.
It became
evident that if the trot base of the breed were to be preserved,
quick action needed to be taken.
It was necessary to identify the foundation type horses
and in some manner collect them into a group
whereby breeders could utilize them to more advantage. It
was also apparent that if a market share was to be developed
for this wonderful style horse, such a goal would get no
backing from the Association at large.
Rather
than tear apart the very small breeding gene pool of the
Missouri Foxtrotting breed, it seemed more
logical to work within the original Association by developing
a secondary registry for the Foundation
type horses. In this manner those horses with the proper
trot/pace ratios could be better matched and
the natural foxtrot gait better preserved.
To do
that meant the limiting of Tennessee Walking Horse blood.
The V-factor is a formula which allows
each horse to carry a known value for pace to trot ratio.
A full blooded Tennessee Walking Horse
receives a factor of V-256. A full Saddlehorse or Morgan
receives a factor of V-0. Cross breds fall
between these two extremes depending upon how many crosses
of TWH are in any given pedigree.
The
Foundation Foxtrotter Heritage Association was formed. It’s
mission is to preserve the original
style Missouri Foxtrotting Horse. Any horse applying for
registry in the Foundation Foxtrotter Heritage
Association must carry a V-factor of 128 or less to qualify
for registry. That means it must be no more
than half Tennessee Walker by blood.
By factoring
and building a data base of these V-factors, breeders can
plot matings to advantage with
a goal to standardize the group to a level conducive to
foxtrot to the exclusion of lateral gaits without
doing away with a natural running walk.
Breeders
can take the V-factor of their mare and match it to the
V-factors of available stallions as part….
Repeat PART…of their considerations for breeding. Breeders
always should compare conformation and match mares well,
but the V-factor will be one more tool they can use to assure
the consistent reproduction of natural foxtrot in their
offspring.
The
V-factor system was taken to Dr. Gus Cothran at Texas A&
M for his learned opinion. He claims the
factoring method to have merit.
Once
the registry has sufficient numbers of horses registered,
Dr. Cothran would like blood samplings
from two dozen low factored horses and samples from high
factored horses to study and compare. The goal would be
to see if at the molecular level he can see a difference
between the two types.
This
year the genome of the horse was complete and the sequencing
released to the equine geneticists of the world. This means
that rather than trying to fathom the complex mysteries
of equine genetics by the use of approximately 12 genetic
markers, these scientists will now have in the neighborhood
of 12,000 genetic markers with which to work. Because of
this dramatically amazing increase in available markers,
Dr. Cothran and other geneticists may soon be unlocking
many of the genetic mysteries of gait.
The
V-factor may well be a very helpful part of some of this
research. We can hope it is and that with
this DNA study of the samplings we can identify the specific
ratios of pace to trot needed to produce
foxtrot into the distant future without the pace diluting
it into extinction.
