Conform ation analysis is the system atic com parison of one horse to another, and all horses to an ideal type for the breed or athletic pu rpose. With good conformation, and that important factor of heart and athletic ability, horses are capable of exceptional athletic performance. This results in uneven distribution of concussion each time the limb impacts the ground, with one area of the bone, joint, or soft tissue structures assuming excessive impact., She cautions against getting hung up on absolutes such as which conformational flaw is better or worse than another. The muscles, especially in the limbs, stabilize the leg and keep joints from hyperflexing or hyperextending as each limb impacts the ground.. Initial attempts to provide absolute values in conformation assessment have used the tools listed in Table 15-2 in combination with a reference marker system. Anatomic Description of Commonly Used Conformational Terms, FIGURE 15-1 Illustrations of some common conformational defects of the forelimbs (see Table 15-1 for description). Two British Columbia Horses Test Positive for EIA, Scientists Validate Safety of Equine Blood Flow Restriction. The literature presented in this chapter will follow the terminology appearing in the research papers. Weller et al. 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. Splayed, feet move forward in larger inward arcs "winging! 3. Introduction Conformation plays an important role in the ability of a horse to perform. Magnusson (1985) showed less variance among judges on overall impressions and type traits. (2006a) found measurement variations in stance within one horse to be almost as large as between horses, thus highlighting the importance of standardized repeatable positioning of the horse. Image: drfgyhjkl (image/png) Answer. Some studies and studbooks have used a system of linear scoring in an attempt to quantify the repeatability of subjective evaluation (, 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. Absorbs excess impact on medial (inner) limb structures. With poor conformation, a horse may be best suited to quiet trail rides. (From Mawdsley A, Kelly EP, Smith FH, Brophy PO: Linear assessment of the thoroughbred horse: an approach to conformation evaluation, Equine Vet J 28:461, 1996). This evaluation may be regarded as the front line for judgments when selecting horses for specific intended tasks, including breeding selection. Although meeting with some success, 6 of 21 traits were classified unacceptably low in repeatability (Mawdsley et al., 1996). The hind cannon bone is usually longer and wider than the front cannon bone. Hindlimb The base of the neck should be level with the point of the shoulder or higher, she says. Bruising, corns, and quarter cracks of medial aspect of the hooves from excess impact. Horses differ in conformation, which affects how well they can perform in different events. Extra ribs allow for a shorter back, which results in stronger coupling of the loin area. There is emerging a new way of assessing conformation in the dynamic realm, until now . What does good conformation mean? 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. If it's too big, then it will add a little extra weight to the forehand which is naturally already carrying around 60 percent of a horse's total weight. Good conformation is key to the intended performance of your horse. They generally appear somewhat uphill in their balance, with a neck that comes relatively high out of the withers, a moderately sloped shoulder, and a very powerful sacrum and pelvis. 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. Email Practical.Horseman@EquiNetwork.com or mail a print to Conformation Clinic, Practical Horseman, 656 Quince Orchard Rd., Suite 600, Gaithersburg, MD 20878. Forefeet differ in size, shape, or both, causing variable hoofground angles ACVIM, of High Desert Equine, in Reno, Nevada, says watching a horse in motion always trumps looking at him standing still. A horse that exhibits correct conformation should be a natural athlete. The various areas horses are evaluated on for overall . 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 pastern angle to the toe should be 40 to 55 degrees. Traditionally described as the metacarpus laterally deviated relative to the carpus; however, the displacement is usually in the radiocarpal joint (Ross, 2003) N. CREVIER-DENOIX. From the rear view, you should be able to draw straight lines down the rear legs. The back should be one-third of the horses length. Ideal front leg conformation. Too big of a head will cause the horse to be clumsy and move heavy on their front. Yet, most studies have employed generalized or horsemanship terms in describing conformational traits. Excess stress on lateral joint surfaces and medial splint bones. When buying a new horse, we tend to look at their conformation. In the hindlimb, a plumb line dropped from the ischial tuberosity should touch the point of the calcaneous (prominent caudally in the tarsus or hock), follow the plantar metatarsal surface to the metatarsophalangeal joint (MTPJ or fetlock) and fall 7.5 to 10 cm caudal to the heel in the lateral view. (From Ross MW: Conformation and lameness. The skeletal format will affect such factors as joint range of motion, limb arc and hoof flight patterns, and weight distribution in motion, with subsequent effects on . A line dropped from the cranial aspect of the greater tubercle of the humerus (point of the shoulder) should bisect the forelimb in the cranial view. 3) What conformation flaw is shown? ( See the figure for . If the red hair comes from the chestnut pattern, the mane, tail, and legs will be red. Shortened, choppy stride with potential to stumble. 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. Veterinarian conformational assessment should particularly focus on the presence of any such faults and the relationship of these faults to existing or potential pathologic conditions (Rossdale and Butterfield, 2006). Lateral tuberosity of the distal end of the radius 3. The hind legs have fewer lameness issues than the front legs because they only carry 40 percent of the horses weight. 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. 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. Lateral tuberosity of the distal end of the radius, 6. Yet, most studies have employed generalized or horsemanship terms in describing conformational traits. Offset knee/bench knee The Horsesexperts answer your questions during a monthly live audio event. Each evaluation location will give you a different perspective of the horse's conformation. Proximal attachment of the lateral collateral ligament of the fetlock joint to the distal end of the third metacarpal bone Selection of a horse in the presence of a less-than-desirable conformation is not always considered unwise. Absorbs excess impact on lateral (outside) limb structures and increases pastern and coffin joint potential for osteoarthritis. When evaluating the conformation of a horse, you should consider the following areas: balance, muscle, structural correctness, and breed and sex characteristics (Figure 1). Tension on hock joints that leads to degenerative arthritis. 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). Webcast | Join us as we interview leading equine researchers from the University of Kentucky, Problem Solver Series: How to Control Nuisance Birds on Horse Properties. Introduction. Jul 8, 2016 | Posted by admin in EQUINE MEDICINE | Comments Off on Conformation. Furnished . Common Term Large formed hocks are better at absorbing concussion and generally make for a sounder joint. The constant growth of the hoof creates a dynamic relationship between the digital axis and dorsal hoof wall, which suggests that completely straight hoofpastern axes cannot exist over time without natural wear or appropriate trimming (Moleman et al., 2006). 2) What conformation flaw is shown? She cites an example of a horse with contracted heels or a. Why were losing our horse doctors and how to begin solving the problem. Initial attempts to provide absolute values in conformation assessment have used the tools listed in Table 15-2 in combination with a reference marker system. Stay up-to-date on the latest news about your horse's health with FREE newsletters from TheHorse.com. Endurance horses experience repetitive concussion at moderate speeds for many consecutive hours. One confor - m ation analysis system is known as BSMQTT: balance, stru ctu re, m u scling, qu ality, type, and travel. Metacarpophalangeal and proximal interphalangeal (pastern) joints have a straight appearance When a horse has a conformational defecttoed in or out, offset cannon bones, benched knees, sickle-hockedbones dont line up correctly at the joints. (2006a) found measurement variations in stance within one horse to be almost as large as between horses, thus. In the hindlimb, a plumb line dropped from the ischial tuberosity should touch the point of the calcaneous (prominent caudally in the tarsus or hock), follow the plantar metatarsal surface to the metatarsophalangeal joint (MTPJ or fetlock) and fall 7.5 to 10 cm caudal to the heel in the lateral view. Ideally, when viewed from the side, you should be able to draw a straight line through the center of the bones of the forearm, knee, cannon and bulb of the heel.
