Assessment of conformation As the horse ages, the proportion of white hair may increase but usually not to the extent this occurs in grey horses. At the walk, however, landing flat is normal. Racehorse conformation and its' potential to predict animal performance - Volume 2009 There are a few characteristics that could point to weak points in our equine's framework. All rights reserved. Equine Nutrition FAQ Series, sponsored by Purina Animal Nutrition. (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. Magnusson (1985) showed less variance among judges on overall impressions and type traits. 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). 3. 3. For both the conformation and movement, young horses are shown on a triangle so they can be seen from all perspectives. FIGURE 15-5 Illustrations of some common conformational defects of the hooves (see Table 15-1 for description). Splayed, feet move forward in larger inward arcs "winging! Restriction of the Achilles tendon sheath leads to thoroughpin (stress on the DDFT, with puffiness in the web of the hock). 5. 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. The elbow should be parallel to the horses body. Conformation is the mixing of the different body parts of the horse, and how well they fit together visually and physically to create a high-performing, talented racehorse. Good conformation is key to the intended performance of your horse. Calipers Nonetheless, conformation can assist prediction of possible musculoskeletal strengths and weaknesses, possible predisposition to injury, or both, based on known etiology and pathophysiology of musculoskeletal disorders. This point puts the horse at threat of lameness because of to instabilities in its gait or motion and way of journey. 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. Louise Dentith MSc, Senior Lecturer, Moulton College discusses the limbs and dynamic conformation of the horse. 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. 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. Width of head and third metacarpal/metatarsalWidth of chest and pelvis 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. A short back also provides more strength for carrying a rider. The absence of standardized evaluation standards, lack of centralized training programs internationally, and a large source of error introduced by subjective assessment precludes sole use of this method to compare results between studies or substantiate the more complex relationships among conformation, performance, and soundness. 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. It affects the looks of a horse - the shape and proportions of its body. Increases winging of hoof flight with potential for interference injury. Common Term The base of the neck should be level with the point of the horses shoulder. Conformation assessment should be a systematic and organized process incorporating a general overall observation of size, symmetry, musculature, posture, balance, and demeanor, followed by a more specific evaluation of conformational traits of the body, individual limbs, and feet. It is critical that the farrier examine the entire bony column of the horse and balance the foot with respect to the weight-bearing forces that result from all aspects of a horses conformation. and more. University of Minnesota Extension discovers science-based solutions, delivers practical education, and engages Minnesotans to build a better future. A horse's back should be shorter than their underline. Why were losing our horse doctors and how to begin solving the problem. Shortened stride length and a more jarring gait for a rider. 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. One strategy for preventing lameness, no matter the horses conformation, is regular and correct hoof trimming and/or shoeing. These traits were hoofpastern axis in both forelimbs and hindlimbs, head size, and vertical alignment of the forelimbs and hindlimbs, all having a coefficient of variation greater than 10%. 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). So, it is sensible to avoid conformational problems like being calf-kneed (back at the knee), which potentially exacerbates hyperextension of these joints. This horse can develop an overall lighter movement that reduces concussive force on the feet and limbs to mitigate the development of forelimb lameness resulting from poor hoof conformation., Riders in many disciplines desire certain neck sets and conformation that lead to musculoskeletal issues, says Collatos. It can be remedied if it is managed from day one but, if it is left, it can cause big problems.". If the red hair comes from the bay pattern, the mane, tail, and legs will be black. 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 coordination of movement (including limb interference), balance, power (propulsion, impulsion, and collection), agility, and endurance. An upright pastern is often also related to this conformation (Ducro et al., 2009a) A founding study by Magnussen (1985) described the comprehensive set of landmarks listed below, and many research studies have followed this protocol or a derivative of it. Conformation also varies with breed, within a breed and between individuals. Conformation will, therefore, partially dictate the relationship between form and function, thus modifying the potential for biomechanical efficiency, superior performance, musculoskeletal durability, and perhaps even longevity (Wallin et al., 2001). Ideally the foot lands slightly heel first at faster gaits (thus the shock absorbing function of the heel). Stay up-to-date on the latest news about your horse's health with FREE newsletters from TheHorse.com. Only gold members can continue reading. (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). If your horse's withers are higher, your horse has uphill balance. Weller et al. 2) What conformation flaw is shown? The veterinarian will study conformation, balance and weight-bearing, as well as ook for any evidence of injury or stress. RELATED CONTENT | 7 Conformation Flaws: Piecing Together What We Know, Contracted heels or a club foot may predispose a horse to concussion-related foot lameness, she says. Dynamic conformation. 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. Horses are more likely to suffer a severe injury when they fatigue, says Duberstein. Proximal end of the spine of the scapula For these, quantitative conformational assessment, in addition to these traditional judging methods, has been suggested to improve predictive capability (Holmstrom and Philipsson, 1993). Carpal arthrosis is more common in racehorses due to hyperextension of their carpal (knee) joints when they fatigue, says Duberstein. Fatigue amplifies such busy limb motion, making the horse more likely to interfere (one foot hitting the other leg) in addition to adding impact more on one side of the hoof and limb than the other.. 4. Back at the knee/calf knee Although meeting with some success, 6 of 21 traits were classified unacceptably low in repeatability (Mawdsley et al., 1996). The segment lengths of specific long bones of limbs should also be noted at this time. Tends to wing the feet with potential for interference injury. The ideal conformation of a young horse for any competition or sound family mount. Conformation: The conformation of a therapy horse (the way its parts are put together), is only important as it relates to weight carrying ability, soundness, and movement. She describes how the forelimbs and hind limbs function differently: The hind limbs generate tremendous propulsion, but more in a horizontal manner, while the front limbs tend to generate a vertical force to push the horse upwards off the ground.. These traits were hoofpastern axis in both forelimbs and hindlimbs, head size, and vertical alignment of the forelimbs and hindlimbs, all having a coefficient of variation greater than 10%. A horse's head needs to be in proportion to the rest of their body. When assessing foal conformation, limbs can also be viewed from above at the shoulder and hip (skyline view). The entire hindlimb should be bisected evenly in the caudal view (see Figure 15-4). A horse needs to be standing squarely and fully weight bearing on all 4 feet to properly evaluate static balance. Certain conformational flaws, such as being built downhill (croup higher than the front end and/or a low-set neck), cause a horse to carry even more weight on his forehand. Figure 1: Difference in shape of the sacrum. A proportionate horse is usually square. Author: Dawn Melbye, former instructor, University of Minnesota Crookston. The segment lengths of specific long bones of limbs should also be noted at this time. Objective conformational evaluation provides a useful adjunct to subjective assessment by quantification of some conformational traits; however, it must be remembered that not all conformational aspects can be measured objectively. The hindquarters influence the horses capacity for: The gaskin and thigh muscles power running, jumping and other forward movements. This means that an imaginary line drawn down the front of the horse's pastern should continue in that line down the front of the hoof wall. They are more prone to stress and injury than the hind legs. 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. 3. Look for the following when evaluating a horse's head. 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. Evaluating Conformation - A Dynamic Process "You don't just look at a horse from a static view, and you don't just look at them from one angle," Adams stressed. A horses conformation is the way it is made up, its structure, how its body parts relate to each other and how it is proportioned. Static vs dynamic conformation. However, training can help develop core strength and flexibility to markedly enhance a horse with less-than-ideal balance or limb conformation. Despite considerable anecdotal information, there is still a considerable lack of evidence-based quantification of conformation assessment and the relationships among conformation, performance, and orthopedic health. In Ross MW, Dyson SJ, editors: Diagnosis and management of lameness in the horse, Philadelphia, PA, 2003, WB Saunders, p 21.) Reasons for performing the study: Assessment of conformation is commonly used in the selection of horses for performance purposes. This line should evenly split the forearm, knee, cannon, fetlock, pastern and hoof. Anatomic Description And, armed with that knowledge, you can take steps to help keep him sound. Attachment of the long lateral ligament of the tibiotarsal joint to the plantar border of the calcaneus, 5. Rather than trying to patch up already-developed lameness issues with palliative care such as joint injections, take a proactive approach by properly selecting and conditioning a horse for your desired athletic enterpriseor selecting a sport in which your horse will exceland having him correctly shod. . Roan horses may have distinct or indistinct white markings. (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. Too small of a head will cause the horse to lack counterbalance and lose suppleness and action in their front. 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. 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). The segment lengths of specific long bones of limbs should also be noted at this time. 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. Sometimes we have a young horse we will need to decide what discipline to train him under, but other times we have a horse doing one "job" but struggling at it. Assessing limbs, feet, and body can help you and your veterinarian identify anatomical traits that could end up being performance-affecting liabilities. The quarters shouldnt be too sloped or flat. However, certain conformational faults such as extreme tarsal angulation (large or small) and tarsal valgus are almost certainly predisposing to injury or lameness in racing events and are best avoided. Screwing motion of footfall leads to foot bruising, corns, and quarter cracks and potential for ringbone (coffin or pastern joint arthritis). The aim of this study was to analyse dynamic load distribution and hoof landing patterns of sound Standardbreds. Generally, a horses neck should be one and a half times the length of the head. Magnusson (1985) showed less variance among judges on overall impressions and type traits. Good chest and rib form leads to strong leg, shoulder and neck attachment, which creates a powerful athletic performer. Conformation can, therefore, only be considered an indicator for future athletic potential. Horses with straighter shoulders and pastern angles tend to have shorter strides. 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. Too big of a head will cause the horse to be clumsy and move heavy on their front. These traits were hoofpastern axis in both forelimbs and hindlimbs, head size, and vertical alignment of the forelimbs and hindlimbs, all having a coefficient of variation greater than 10%. Conformation: The conformation of a horse refers to how the horse is built. Orthobiologic Options for Treating Horses. Log In or Register a > to continue The Horsesexperts answer your questions during a monthly live audio event. However, opinions concerning segment lengths, joint angles, and skeletal inclinations were largely discrepant. Therefore, Quarter Horse conformation tends to be downhill with tremendous power and musculature in the sacrum, hips, and thighs to enable them to dig in, turn, and go. 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. Space between the fourth tarsal, the third metatarsal, and the fourth metatarsal bones, 6. Jul 8, 2016 | Posted by admin in EQUINE MEDICINE | Comments Off on Conformation. Collaborate with your veterinarian, as well, using radiographs (X rays) to evaluate hoof angles and foot placement and guide shoeing and trimming recommendations. Establishing the exact source of the alignment deviation is imperative; for example, does a laterally pointing hoof, commonly described as toed out, originate from an externally rotated limb or from a particular distal joint? . Log In or, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), 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. This allows the horse to be more flexible, balanced and collect more naturally. A shorter hindquarter supports power and strength. For these, quantitative conformational assessment, in addition to these traditional judging methods, has been suggested to improve predictive capability (Holmstrom and Philipsson, 1993). Front Leg Conformation. Flatter Croups.
