Topic:Farriery
Farriery involves the skilled practice of hoof care and shoeing in horses, focusing on the maintenance and management of equine hooves. The process includes trimming and balancing the hooves, as well as the application of horseshoes when necessary. Farriery plays a role in supporting the overall health, performance, and comfort of horses by addressing issues related to hoof growth, structure, and function. Various techniques and materials are employed to accommodate different hoof conditions and activities. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, materials, and implications of farriery in equine health and welfare.
Compensation for changes in hoof conformation between shoeing sessions through the adaptation of angular kinematics of the distal segments of the limbs of horses. To determine the mechanism that enables horses to partially counteract the shift of the center of pressure under the hoof induced by changes in hoof morphology attributable to growth and wear during a shoeing interval. Methods: 18 clinically sound Warmblood horses. Methods: Horses were evaluated 2 days and 8 weeks after shoeing during trotting on a track containing pressure-force measuring plates and by use of a synchronous infrared gait analysis system set at a frequency of 240 Hz. All feet were trimmed toward straight alignment of the proximal, middle, and distal phalanges and shod with stan...
The effect of hoof trimming on radiographic measurements of the front feet of normal Warmblood horses. The understanding of the normal position of the third phalanx (P3) and the distal sesamoid bone in relation to the size and shape of the hoof capsule in sound horses is helpful in the diagnosis of equine foot lameness. Some measurements on radiographs used to define the position of the pedal bone within the hoof capsule are significantly influenced by hoof trimming and the height of the withers. In this study, the front hooves of 40 Warmblood horses were radiographed twice, eight weeks apart, both before and after their hooves were trimmed by an experienced farrier. Using the software programm...
Shoeing sound warmblood horses with a rolled toe optimises hoof-unrollment and lowers peak loading during breakover. Overload injuries in sport horses commonly occur; shoeing techniques are believed to be important in prevention of these injuries, but there is a paucity of scientific information identifying the potential connection. Objective: To test a horseshoe with a modified rolled toe designed to ease the process of breakover and decrease loading of lesion-prone structures of the distal limb. Methods: Twenty clinically sound Warmblood horses trotted over a track containing a pressure/force measuring system and 6 infrared cameras. The horses were measured with 2 types of shoes, standard flat shoes and sh...
Hoof growth between two shoeing sessions leads to a substantial increase of the moment about the distal, but not the proximal, interphalangeal joint. There is little insight into the effects of routine farriery on the internal structures of the distal limb in sound horses. Objective: To measure the effect of change in hoof conformation during a shoeing interval on the moments about the proximal and distal interphalangeal joints (PIPJ, DIPJ) and to determine whether and how the horse compensates for this change in hoof conformation. Methods: Both front feet of 9 sound Warmblood horses were measured while standing on a pressure-force measuring system and radiographed in a lateromedial direction shortly after shoeing and 8 weeks later. From th...
[The art of horseshoeing–between empiricism and science]. To correctly shoe a horse requires the farriers to have a good working knowledge of postural anomalies and movement patterns, as well as of the different concepts of horseshoeing and to be able to apply the appropriate technique to every individual horse they shoe. The correct technique for specific problem cases is frequently a subject of debate amongst specialists and many theories would benefit from objective gait analyses. The case study presented examines the influence of different shoeing conditions on selected gait analysis parameters. The measurements were conducted on a Warmblood mare...
[Interactive educational DVD on hoof protection, horseshoeing and diseases of the hoof]. Good cooperation between farrier, veterinarian and horse owner is an important prerequisite for optimal support of the horse with regards to shoeing and hoof health. The introduction of a joint educational aid aims to improve the level of education of both veterinarians and farriers. The interactive, multimedia approach represents an innovative new dimension in instruction techniques, predominantly provided through images and videos. The contents of the new teaching aid will focus on detailed anatomy of the foot and distal limb, as well as currently accepted shoeing practices and techniques an...
[Do we need a quality control for horse shoes and farriery]. In the past few years marked changes in the field of farriery have been noted. In addition to the classical farrier, many new occupations concerned with hoof care have emerged, such as hoof trimmer, hoof technician, hoof orthopedist and hoof naturopath. Furthermore, a tremendous number of hoof protection systems have been developed, with an ever-increasing application to horses. However, regulations regarding alternative shoeing methods are insufficient and it is not clear, who governs the quality of the work of the individuals involved. Thus, a neutral authority composed of farriers and veter...
[Do hoof cracks represent a superficial hoof-problem?]. Fifty-four horses with hoof cracks were referred to the Equine Hospital of the University of Zurich, for treatment. The horses were admitted because of lameness or other symptoms caused by the cracks. Deep or complicated quarter cracks were the most common type of cracks diagnosed. Poor conformation and abnormal hoof shape were the most important causes of hoof crack development, whereas injury to the coronary band was a less frequently encountered cause. Effective treatment of this problem includes corrective shoeing, removing horn from the weight-bearing surface as well as from the crack wit...
Use of gyroscopic sensors for objective evaluation of trimming and shoeing to alter time between heel and toe lift-off at end of the stance phase in horses walking and trotting on a treadmill. To determine whether a shoe with an axialcontoured lateral branch would induce greater lateral roll of the forelimb hoof during the time between heel and toe lift-off at end of the stance phase (breakover). Animals-10 adult horses. Methods: A gyroscopic transducer was placed on the hoof of the right forelimb and connected to a transmitter. Data on hoof angular velocity were collected as each horse walked and trotted on a treadmill before (treatment 1, no trim-no shoe) and after 2 treatments by a farrier (treatment 2, trim-standard shoe; and treatment 3, trim-contoured shoe). Data were converte...
Changes in location of centre of pressure and hoof-unrollment pattern in relation to an 8-week shoeing interval in the horse. In order to optimise shoeing and shoeing conditions, it is essential to know how the horse adapts to a common shoeing interval. Objective: To measure changes in location of the centre of pressure (CoP) and hoof-unrollment pattern during a shoeing interval and to assess whether these changes in CoP result directly from changes in hoof conformation or are also influenced by compensatory mechanisms. Methods: Eighteen horses were trotted over a pressure-force measurement system shortly after shoeing and 8 weeks later. The position of the CoP was measured and also predicted using calculations based...
Deep digital flexor tendon force and digital mechanics in normal ponies and ponies with rotation of the distal phalanx as a sequel to laminitis. Previous studies have implicated tension in the deep digital flexor tendon (DDFT) in the rotation of the distal phalanx (DP) after the breakdown of the dorsal laminae caused by laminitis. Howeveer, once the DP has rotated, the DDFT should become shorter, reducing the force it exerts on the DP. Objective: To compare DDFT force and ground reaction forces (GRFs) in normal ponies and ponies with rotation of the DP as a sequel to laminitis. Methods: Six normal ponies (Group 1) and 6 sound ponies with 6-13 degrees of rotation of the DP in relation to the dorsal hoof wall (Group 2) were assessed at t...
Dynamic pressure measurements for the detailed study of hoof balance: the effect of trimming. Studies on hoof balance have, so far, only assessed the effects of strong and relatively unrealistic interventions due to technical limitations of measuring equipment. For the assessment of more subtle interventions, other techniques are necessary. Objective: To test a sensitive pressure measurement system during locomotion and to set a standard for further studies by using the system to evaluate the effects of trimming. Methods: Eighteen horses were measured before and after trimming with an interval of 4 weeks. Trimming was standardised to a straight hoof-pastern axis. The horses trotted ove...
Observer variation in visual assessment of forelimb horseshoe characteristics on Thoroughbred racehorses. To assess the accuracy and reliability of a visual method of evaluating horseshoe characteristics. Methods: 1,199 Thoroughbred racehorses. Methods: Characteristics of 1 forelimb horseshoe were visually assessed on horses immediately prior to racing by 5 field observers at 5 major racetracks in California. Characteristics evaluated included horseshoe type; toe grab height; and the presence of a rim, pad, and heel traction devices. Sensitivity and specificity for observer assessment of horseshoe characteristics were calculated by comparing observer assessments to a postmortem laboratory standard...
Relationship of foot conformation and force applied to the navicular bone of sound horses at the trot. Collapsed heels conformation has been implicated as causing radical biomechanical alterations, predisposing horses to navicular disease. However, the correlation between hoof conformation and the forces exerted on the navicular bone has not been documented. Objective: The angle of the distal phalanx in relation to the ground is correlated to the degree of heel collapse and foot conformation is correlated to the compressive force exerted by the deep digital flexor tendon on the navicular bone. Methods: Thirty-one shod Irish Draught-cross type horses in routine work and farriery care were trotte...
Radiographic imaging of the equine foot. Radiographic examination of the equine foot can provide the veterinarian and farrier with a wealth of information. Positioning and selection of exposure factors are of central importance if one is to produce radiographs of maximum diagnostic value.
Natural balance trimming and shoeing: its theory and application. The principles and techniques of natural balance trimming and shoeing are designed to optimize the efficiency and function of the foot. The basic guidelines have evolved in part from wild horse hoof imprint studies done in 1986 through 1987 and first presented in 1995. Further research has contributed to these principles and guidelines to make them applicable to domestic horses.
Foot management in the foal and weanling. Foot management and hoof care of foals, weanlings, and yearlings tends to be considered a specialist job. Many farriers and veterinary surgeons have little exposure to young and growing stock. Nevertheless, a variety of angular and flexural limb deformities can benefit from simple podiatry techniques, which can be performed provided that a few basic rules are followed. The combined skills of the farrier and veterinary surgeon offer many young horses with angular or flexural limb deformities a chance of a future athletic career.
Proper physiologic horseshoeing. Adherence to the basic principles of physiologic horseshoeing is essential to maintaining hoof health and soundness. Most horses do not require special trimming or shoeing techniques. Becoming familiar with a few basic concepts can help the veterinarian to recognize when changes in trimming or shoeing might be expected to help the performance of a sound horse or might help to restore the performance of one that is lame. Sound physiologic horseshoeing can only be achieved by a thorough knowledge of, strict adherence to, and skillful application of basic principles, such as hoof angle, HPA, and ...
Hoof wall defects: chronic hoof wall separations and hoof wall cracks. Hoof wall defects in horses are common occurrences, and, fortunately, many of those detected present little or no danger to the individual horse. Those defects that are either presently a problem or have a great likelihood of being a problem do often require specialized consideration. Horse shoeing and farriery are ancient practices; over the years, a multitude of methods, theories, and management schemes have been proposed. It is unfortunate to note that few studies are available to provide an accurate incidence rate, a better understanding of the various causes, and, lastly, a comparative ap...
Hoof repair and glue-on shoe adhesive technology. There are many different commercially available hoof repair/adhesive products. The application of these products in the treatment of various foot conditions is continuing to evolve based on sound medical and farriery principles as well as imagination. Successful application of these products depends largely on using proper hoof wall preparation and adhesive application techniques. Success also depends on a realistic expectation of the final outcome when accounting for the physical limitations of the adhesive products and the underlying hoof problem. Our results with these techniques have been ...
Diagnosis, treatment, and farriery for horses with chronic heel pain. In conclusion, horses with heel or navicular area pain vary, and no one treatment option is suitable for all horses. Each horse must be evaluated individually to determine which structure in the palmar aspect of the foot is injured, severity of disease, horse and hoof conformation, and horse use and level of performance expectation before a treatment plan can be developed. Overall, there are many treatment options to help these horses to perform their intended athletic event.
The role and importance of farriery in equine veterinary practice. There is a lot of room for us to become the central source of medical information regarding shoeing and lameness in our own practice area. This takes a good bit of effort and a real "outreach" to client and farrier. It can be done with the one tool we are best at--the acquisition and careful dispensing of information that we can put together regarding the health of the foot. Such information includes the following: 1. Radiographically guided hoof trimming and shoeing. 2. Ultrasonography. 3. Digital radiography. 4. Thermography. 5. Nutritional and health counseling. Become the "local" expert in...
Effect of foot balance on the intra-articular pressure in the distal interphalangeal joint in vitro. Increased joint pressure has been implicated in the progression of osteoarthritis. Objective: That intra-articular pressure in the distal interphalangeal joint (DIP) is significantly higher in legs loaded with heel up (HU), low heel (TU), lateral side up (LU) and medial side up (MU) imbalance compared to the balanced position. Methods: Twelve elbow down limbs were compressed in a hydraulic loading jig and DIP pressure measured. Results: Elevating the heels by 5 degrees significantly increased DIP pressure. After 5 ml of contrast was injected into the joint, heel elevation caused a greater incr...
Short-term effect of therapeutic shoeing on severity of lameness in horses with chronic laminitis. To evaluate the short-term effects of 4 therapeutic shoeing systems on lameness and voluntary limb-load distribution in horses with chronic laminitis. Methods: 10 horses with chronic laminitis. Methods: A clinical trial was conducted that used a concurrent control, crossover design to evaluate the relative effectiveness of a standard flat shoe, fullered egg-bar shoe, heart-bar shoe, and modified equine digital support system to alleviate chronic lameness in horses. Therapeutic success was assessed during a 7-day period by use of subjective (Obel grade and clinical score) and objective (force-p...
The effect of frog pressure and downward vertical load on hoof wall weight-bearing and third phalanx displacement in the horse–an in vitro study. A shoe was designed to combine the advantages of a reverse shoe and an adjustable heart bar shoe in the treatment of chronic laminitis. This reverse even frog pressure (REFP) shoe applies pressure uniformly over a large area of the frog solar surface. Pressure is applied vertically upward parallel to the solar surface of the frog and can be increased or decreased as required. Five clinically healthy horses were humanely euthanased and their dismembered forelimbs used in an in vitro study. Frog pressure was measured by strain gauges applied to the ground surface of the carrying tab portion of t...
Three-dimensional kinematics of the equine interphalangeal joints: articular impact of asymmetric bearing. The objective of this study was to assess the effects of asymmetric placement of the foot on the three-dimensional motions of the interphalangeal joints. Four isolated forelimbs were used. Trihedrons, made of three axes fitted with reflective markers, were screwed into each phalanx. They allowed to establish a local frame associated with each bone and thus to define the spatial orientation of the phalanges. The limbs were then placed under a power press, and subjected to compression with gradually increasing force (from 500 to 6 000 N). The procedure was performed in neutral position and with ...
