Conformation Evaluation-Purpose
Purpose of evaluation (judging) is to identify and breed superior individuals
This should (or, at least, could) increase our chances of performance capability
FORM ----relates to----> FUNCTION(typically or most of the time)

Structural Correctness
There are many characteristics of structural correctness that are desirable for most breeds
Some bones are long for increased muscle attachment
Some bones are short for strength
Structural correctness also includes the way in which the horse’s parts are put together
![Page 7: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/7.jpg)
Structural Correctness
Shoulder, slope should be the same on each animal---approximately 45 degree angle.
- point of shoulder to mid-withers- a long, well laid back shoulder allows:
* a wider range of movement * more shock absorption capability
![Page 8: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/8.jpg)
Structural Correctness
Neck, is used for a lever and counterbalance during movement: a thin and clean neck will allow the horse to be more supple and flexible in its movement
- neck should be medium length - attachment to shoulder will vary depending on breed; the lower attachment of neck - throatlatch
clean for flexion
![Page 9: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/9.jpg)
Structural Correctness
Back, is the weight bearing area (for rider or foaling mares)
The back (withers to loin) should be short in relation to the underline
A long underline allows more area for stride and containment of vital organs
Heartgirth should be deep; hindrib should be deep
![Page 10: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/10.jpg)
Structural Correctness
Loin, or coupling area should be well-muscled and moderate in length
The loin is the flexible area in the spine, and allows the horse to bring the hindquarters up “under” the body to even out the distribution of body weight
![Page 11: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/11.jpg)
Structural Correctness
Croup and Hip, areas should be long and well muscled to allow for more impulsion from the hindquarters
The croup slope will be different depending on breed
The hip should be measured from tuber coxae to tuber ischii “hooks-pins”
![Page 12: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/12.jpg)
Structural Correctness
Front Legs (front view), the chestfloor should be relatively wide
The front legs and feet should be straight down from the shoulder, through the knee, through the cannon, and through the hoof.
![Page 13: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/13.jpg)
Structural Correctness
Hind Legs (rear view), should be wide set apart (similar to the front legs)
Have a straight line from point of buttock through hocks, cannon bones, and hoof
![Page 14: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/14.jpg)

Structural Correctness
Front Legs (side view), should be straight from mid-scapula through the knee, through the fetlock and to the ground
The front pastern should be medium in length and be the same slope as shoulder and hoof (generally about 45 degrees)
![Page 16: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/16.jpg)
Structural Correctness
Hind Legs (side view), should have an angle or “set” to the hock
The hind cannon should be straight and directly below the point of buttock
The hind pasterns should be of medium length and the same slope as the hoof (which will be slightly steeper than front)
![Page 17: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/17.jpg)
Structural Correctness

Travel
Can actually be considered as part of structural correctness
Can be considered as part of structural correctness because straightness of travel is correlated with correctness of structure
![Page 19: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/19.jpg)
Travel
We evaluate how horses “track” by viewing their movement from the front, rear and the side
How a horse travels depends on the straightness of their feet and legs are….and how the legs tie into the body of the horse– ASPECTS OF TRAVEL:
STRAIGHTNESS WIDTH LENGTH OF STRIDE SNAP AND FLEXION
![Page 20: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/20.jpg)
Travel
Travel should be straight, true, and wide; this is best determined when using the front and rear views to watch the horse move….it can also be observed by checking the hoof prints in the ground
Items such as length of stride and overstepping can best be determined when using a side view to watch the horse move….overstepping can also be noticed by listening for the clicking of the hooves
![Page 21: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/21.jpg)
Travel & Structure Travel and structure are inter-related because without
proper structure, proper travel is not possible.
In terms of travel and structure: proper typically refers to or means straight….or straightness of joints, such as the knee because of all the correct positioning required of the tendons, ligaments, etc needed to have proper structure and travel….which leads to better performance of the horse.

Muscling
Quality of Muscling is important in all breeds
There will be breed differences
Have enough muscling to do the job required
It is important to judge like types
![Page 23: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/23.jpg)
Examination Of Muscling
Muscling can best be examined on the horse in the following areas:
pectoralforearmshoulder loin
croup & hip stifle
gaskin
![Page 24: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/24.jpg)
Quality Of Muscling
Quality of Muscling includes:– Long, smooth, low-tying muscles
muscles that tie low into the joint
– Muscling should be balanced throughout the body
hindquarter versus forequarter muscling
![Page 25: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/25.jpg)
Quality Of Muscling
The muscling of this horse is long and smooth, meaning that is carries down in to gaskin....it is not carried high, meaning that is not bunched on the rump or croup. Long and smooth muscling provides for longer and smoother strides…thus obtaining better performance from the horse Photo: EQUUS
![Page 26: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/26.jpg)
Balance
A well balanced horse has parts that “fit” together
Shoulder, back and hip are about the same length
Heartgirth and legs are about the same length
Length of body and height at withers are about the same measurement
![Page 27: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/27.jpg)
Type
Modern Type….which is a horse that is taller than it is long
Old Type….which is a horse that is longer than it is tall
![Page 28: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/28.jpg)
Quality
Quality is difficult to evaluate until you have had some experience at viewing horses
Quality includes: style sex
character breed character
usefulness factors
![Page 29: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/29.jpg)
Style
Is the relationship of or between the balance and the type of the horse
Is also this combination as it relates to the muscling of the horse
![Page 30: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/30.jpg)
Style
The 2 most reliable indicators of quality are: head
bone
Head: large eyes, erect ears, cleanness of head
Bone: Cleanness of joints, “flat” cannon bones
![Page 31: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/31.jpg)
Sex Character
Stallion: Larger boned; larger jaw; more heavily muscled; wider neck
Mare: Feminine in appearance; smaller boned; narrower and more tapered in the face with a smaller muzzle
Gelding: Somewhere in between
![Page 32: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/32.jpg)
Breed Character
Will be dependent on use of the animal
For example: Major differences between the Quarter Horse and Arabian?

A pigeon-toed horse will travel in what manner?
![Page 35: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/35.jpg)
Blemishes And Unsoundnesses
Blemish = an imperfection which may affect the value of the horse, but does not affect the serviceability
Unsoundness = an imperfection in the horse that affects serviceability
Soundness = useful for a certain purpose, as a result a horse may be sound for one purpose and not for another purpose
![Page 36: Conformation Evaluation Of Horses 2007 Stephen R Schafer, EdD University of Wyoming 2001 D. Karen Hansen, PhD University of Wyoming](https://reader031.vdocument.in/reader031/viewer/2022012922/56649d555503460f94a32efb/html5/thumbnails/36.jpg)

Conformation---Summary
Conformation = how form relates/function
Conformation is founded or based upon:– Structural Correctness (how skeleton fits together)– Travel (how the horse moves)– Muscling (long/smooth is desired)– Balance (relationship of the above three items)– Type (modern type, taller than long, is preferred)– Quality (overall blend and assessment of features)
