The opposite of a ewe neck, with a pronounced curve on the topline, but still a conformation fault, as the horse will not go correctly and may hollow his back. All assessment of equine conformation should be conducted with the horse standing squarely (loading all limbs symmetrically) on a level surface. However, opinions concerning segment lengths, joint angles, and skeletal inclinations were largely discrepant. CHAPTER 15 There is emerging a new way of assessing conformation in the dynamic realm, until now . Smaller-Footed Horses. The various areas horses are evaluated on for overall . The absence of standardized evaluation standards, lack of centralized training programs internationally, and a large source of error introduced by. (See "The Triangle: A Tool for Quick, Accurate Assessment.") Judging Conformation. Regents of the University of Minnesota. To evaluate conformation you need to take a walk around the horse, examine it close up, then again from 20-30 feet away and when the horse is in motion. In Ross MW, Dyson SJ, editors: Diagnosis and management of lameness in the horse, Philadelphia, PA, 2003, WB Saunders, p 21.) Either a rotational change in the hindlimb or tarsus valgus >180 degrees From the rear view, you should be able to draw straight lines down the rear legs. Using shoe branch extensions to attempt to twist a horses toed-in or toed-out conformation to what is considered normal can also create long-term problems, pain, and lameness. Although different breeds will have feet of different shapes and sizes, it is universally and anecdotally desirable to have balanced feet positioned symmetrically under the central limb axis with a straight hoofpastern axis (the dorsal surface of the hoof wall lies parallel to the dorsal surface of the pastern region) (see Figure 15-3 and Figure 15-5). Despite these limitations, subjective evaluation can be easily and quickly performed by an experienced evaluator, expediting the assessment of large numbers of horses within a short time frame. This decreases pressure on the tendons and maintains soundness. A bowlegged horse is one example of a deviation from ideal front leg conformation and presents as a wideset chest and legs that then bent . Static vs dynamic conformation. All assessment of equine conformation should be conducted with the horse standing squarely (loading all limbs symmetrically) on a level surface. However, opinions concerning segment lengths, joint angles, and skeletal inclinations were largely discrepant. The Head. The major disadvantages in using these methods are the possible errors introduced by marker placement on skeletal landmarks, particularly in the proximal skeleton, the consequent reliability of findings, and the time required to perform the measurements (Weller et al., 2006a). The combinations of joint configurations and segment lengths are infinite and multifaceted, so the resulting judgment is variable and directly dependent on the individual expertise and personal ideal of the practitioner. The combinations of joint configurations and segment lengths are infinite and multifaceted, so the resulting judgment is variable and directly dependent on the individual expertise and personal ideal of the practitioner. When considering conformation, Chrysann Collatos, VMD, PhD, Dipl. Some breeds of horse have heavier or rounder muscles than others. 5. Briefly, relevant body observations should include head shape and size; height at the withers and croup; body length; neck length; shoulder length (top of the withers to point of the shoulder); pelvic length (tuber coxae to tuber ischii); scapular and humeral inclination; pelvic and femoral inclination; and chest width. Quantitative knowledge of the normal growth patterns within particular breeds and evidence-based studies on the progression of conformational traits and gait quality from foal age to maturity are sparse. Ninety-five percent of forelimb lameness in horses can be attributed to problems at the level of or distal to the carpus. Horses that have spring of rib: The back transfers the force and driving power from the hind legs. Conformation of the horse's front legs can affect their athletic ability, soundness, stride, speed and agility. A good farrier balances the horse, not just the foot., In horses with limb deviations, hoof angles tend to develop imbalances more quickly than horses with good limb conformation because the way the crooked leg moves causes uneven wear on the hoof, adds Duberstein. This finding was supported by a study comparing radiographic and visual assessments of hoofpastern conformation in Warmblood foals (Kroekenstoel et al., 2006).Visual assessment was only in agreement with radiologic evidence in 6 of 92 (6.5%) evaluations. The combinations of joint configurations and segment lengths are infinite and multifaceted, so the resulting judgment is variable and directly dependent on the individual expertise and personal ideal of the practitioner. After assessment, overall observations can be related to desirable or benchmark breed-specific conformational characteristics and judgment made on the horses suitability to a given career. Proximal attachment of the lateral collateral ligament of the fetlock joint to the distal end of the third metatarsal bone Bruising, corns, and quarter cracks of medial aspect of the hooves from excess impact. Horses that carry themselves in a way that generates less impact when they land likely do less damage to bones and joints than those individuals that come crashing down with each step., Toed-in (carpal or tarsal or fetlock varus), Toed-out (carpal or tarsal or fetlock valgus). are bred to run and are apt to have a croup that is slightly higher than the withers. For global advancement in this area of study, it is clearly imperative to use universally comparative methodology, which is somewhat lacking. Although meeting with some success, 6 of 21 traits were classified unacceptably low in repeatability (Mawdsley et al., 1996). The conformation or inherent anatomic structure of the horse is an integral part of the equine musculoskeletal constitution and will influence the quality of dynamic performance.

Proximal end of the tuber coxae FIGURE 15-2 Illustrations of some common conformational defects of the hindlimbs (see Table 15-1 for description). Stay on top of the most recent Horse Health news with, IF YOU ARE INTERESTED IN ADOPTING THIS HORSE, PLEASE SUBMIT AN ADOPTION INQUIRY VIA OUR WEBSITE: ALLABOUTEQUINE dot ORG. Repetitive motion can lead to osteoarthritis development over time. One confor - m ation analysis system is known as BSMQTT: balance, stru ctu re, m u scling, qu ality, type, and travel. Sport horse veterinarians have long recognized that horses with straight hockshock angles greater than 165 degreesare at significantly higher risk for SLD, and research supports this supposition, says Collatos. Magnusson (1985) showed less variance among judges on overall impressions and type traits. Notably, the definition and number of traits evaluated, the point scale scoring system of conformational traits, and the image of an ideal phenotype varies greatly among registries, organizations, and countries; therefore, specific classification is essential for comparative evaluations. If skeletal bones articulate (join) correctly, the line of concussion that runs up the leg when the horse hits the ground is evenly distributed all the way up the limb, explains Kylee Jo Duberstein, PhD, associate professor of equine science at the University of Georgia, in Athens. (2006a) found measurement variations in stance within one horse to be almost as large as between horses, thus. The croup helps transfer energy for thrust and power from the hindquarters. The entire hindlimb should be bisected evenly in the caudal view (see Figure 15-4). (2006c) also suggested that variability in judgment is affected by the limited repeatability of measurement techniques due to inaccurate identification of anatomic landmarks and inconsistent positioning of the subject. She cites an example of a horse with contracted heels or a. Although meeting with some success, 6 of 21 traits were classified unacceptably low in repeatability (Mawdsley et al., 1996). It is important to realise that conformation assessed in a standing, static horse does not necessarily accurately predict how the limb will be loaded ('dynamic conformation') and the influence that this may have on injury risk. Congruent sloping angulation of the shoulder and hip is also desirable, with a proportional length of individual limbs in relation to the height and size of the body (Figure 15-3). Despite these limitations, subjective evaluation can be easily and quickly performed by an experienced evaluator, expediting the assessment of large numbers of horses within a short time frame. Cranial, caudal, and lateral views are needed to determine limb deviations in the sagittal, coronal (frontal), and transverse planes (see, When examining the conformational traits of individual limbs, a plumb line approach is useful in identifying angular or torsional deviation of segments from the vertical or horizontal at each joint level (Figure 15-4). For example, a caudal deviation at the radiocarpal or metacarpal joint complex (knee) may be described as back at the knee, calf knee, or carpal hyperextension, none of which describes the precise origin of segmental misalignment. Webcast | Particular attention is warranted in evaluation of distal limb alignment, hoof quality, size, and balance due to the concentration of locomotive stresses in this area. At the walk, however, landing flat is normal. Generally, a horses neck should be one and a half times the length of the head. While theres no such thing as perfect conformation, certain structural qualities and alignments are more likely to support soundness than others. The walk and trot should be checked both under saddle and in hand. Predispose to degenerative joint disease (hock spavin) and curb (plantar ligament strain). Forefeet differ in size, shape, or both, causing variable hoofground angles How Organized Are Your Horses Health Records? Posted by Nancy S. Loving, DVM | Oct 19, 2021 | Breeding and Reproduction, Conformation Problems, Forelimb, Hindlimb, Hoof Problems, Horse Care, Lameness, Limb Anatomy & Physiology, Lower Limb, Other Conformation Topics, Sports Medicine. There is a great need to clarify and standardize the descriptive terminology of joint alignments, as most conformational traits are described using multiple traditional and variable nonscientific terms, rather than by defining anatomic configuration. Conformation refers to the shape or structure of a horse, and it can impact a horse's athletic ability. The quarters shouldnt be too sloped or flat. Chestnut: a small calloused are on the inside of each leg. Illustrations of some common conformational defects of the forelimbs (see Table 15-1 for description). Coronet: The coronet is a layer of skin that encircles the top of the hoof . Balance = the relationship between the forehand and hindquarters, the limbs and the trunk of the body, and the right and the left sides of the horse A well-balanced hor se has a ACVIM, of High Desert Equine, in Reno, Nevada, says watching a horse in motion always trumps looking at him standing still. Whether barefoot or shod, the resilience to withstand the stresses of competition and to achieve athletic longevity is enhanced by a balanced foot, says Collatos. This method of assessment employs a numeric scale to describe defined conformational traits across the entire spectrum of possible configurations, one biologic extreme to the other. The head should be in proportion to the rest of the horse. 7. Name of breed: Shire Country of origin: England Breed origin: The Shire is a breed of draught horse that originated in England in the 17 th century. Horses with poor conformation may be at higher risk of: The basic conformation rules allow you to review a horses athletic ability for a certain performance. When assessing deviation of the limb from the vertical, Weller et al. Sickle hock/curby hock Conformation. The neck should tie into the horse's body fairly high with a distinct chest area below. The veterinarian will study conformation, balance and weight-bearing, as well as ook for any evidence of injury or stress. Aesthetic factors such as athletic elegance, suppleness, overall balance and harmony, jumping style, and movement symmetry are necessarily subjectively based. Proximal attachment of the lateral collateral ligament of the stifle joint to the femur, 4. Attachment of the long lateral ligament of the tibiotarsal joint to the plantar border of the calcaneus Equine Nutrition FAQ Series, sponsored by Purina Animal Nutrition. Other factors such as human management, environmental conditions, genetics, nutrition, temperament, training, and the health status of the horse will also have a large bearing on ultimate performance. The lack of anatomic precision, documentation, or both limits the interpretation of some studies. Correct legs structure can improve desired performance and reduce lameness. A horse with good balance always has an attractive profile, which means he appeals to the eye. In Ross MW, Dyson SJ, editors: Diagnosis and management of lameness in the horse, Philadelphia, PA, 2003, WB Saunders, p 21.). Developing a horses entire body to be strong at the center and balanced from front to back helps overcome many conformational problems.. As some conformational traits are dynamic and will only be apparent during ambulation, the traditional emphasis of conformational assessment as a pure description of static external appearance has been extended to include a more functional assessment of conformation during unridden and ridden gaits in some of the studies cited in this chapter.
