This study aimed to create an evidence base for detection of stance-phase timings from motion capture in horses. The objective was to compare the accuracy (bias) and precision (SD) for five published algorithms for the detection of hoof-on and hoof-off using force plates as the reference standard. Six horses were walked and trotted over eight force plates surrounded by a synchronised 12-camera ...

OBJECTIVE To define a 3-dimensional (3-D) coordinate system with clear definitions of origins and axes relative to hoof anatomic features and determine whether solar surfaces of Thoroughbred racehorse hooves have geometric asymmetry in the mediolateral and dorsopalmar directions. SAMPLE POPULATION Left forelimb hooves from 20 Thoroughbred racehorse cadavers. PROCEDURE A right-handed 3-D coo...

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 he...

To achieve this goal, Heatime RuminAct technical equipment used. Data gathering took place farm Un...

Tensile moduli and J-integral fracture toughness values were determined for horse hoof-wall keratin at four hydration levels. The stiffness of hoof-wall was influenced by water content to a greater degree than is the stiffness of other mammalian hard keratins. Young's modulus increased from 410 MPa at 100% relative hydration (RH) to 14.6 GPa at 0% RH. Fracture toughness was maximal (22.8 kJ m-2...

A pelleted ration was fed limited or ad libiturn to two groups of seven Shetland 8month-old ponies for 117 days. During the last 56 days, gelatin was added to the diets of four animals in each of the two intake groups. Gelatin was added at levels of 30 and 90 g per 100 kg body weight for the first and second 28-day periods, respectively. Ponies fed the diet ad libitum consumed 180% more feed, h...

Horses belong to the order Perissodactyla and bear the majority of their weight on their third toe; therefore, tremendous force is applied to each hoof. An inherited disease characterized by a phenotype restricted to the dorsal hoof wall was identified in the Connemara pony. Hoof wall separation disease (HWSD) manifests clinically as separation of the dorsal hoof wall along the weight-bearing s...

This study uses elliptic Fourier analysis (EFA), an outline method of shape analysis, for describing hoof contours symmetries in the Catalan Pyrenean Horse (“Cavall Pirinenc Català”, CPC), a breed from the Spanish Pyrenees. Hoof outlines of 54 limbs (26 forelimbs and 28 hindlimbs, including the same number of left and right limbs) obtained from 15 CPC horses were compared using EFA. Symmetry wa...
