An engineering fracture mechanics approach was applied to the analysis of the fracture resistance of equine hoof-wall. The relationship between fracture toughness and the morphological organization of the keratin hoof tissue was investigated. Fracture toughness was evaluated using the J-integral analysis method which employs the compact tension test geometry. Tensile tests were also conducted t...

Objectives The goal of this study was to quantify external and internal anatomical characteristics of the foal foot throughout the first year of age. Methods Digital radiographs and photographs were taken bimonthly of the forefeet of nine Arabian foals, beginning at about 2 weeks of age until 12 months of age. Sixty-eight linear and angular variables were measured using NIH (National Institutes...

A rare case of multiple mandibular fractures and severe facial laceration is presented. The cause was a horse hoof kick to an unmounted equestrian. The pertinent literature is reviewed and the maxillofacial injuries associated with animal interaction are discussed.

this study was carried out in the winter of the year 2007 in a dairy herd at the vicinity of tehran (eslamshahr). measurements were performed on 18 holstein cows during first-lactation. five holstein dairy cattle were randomly selected and clinically studied, too. length of the claw’s dorsal flexure was measured with a ruler and also the hooves trimmed in the toe vertically for measuring of the...

Polypeptides that form 10-nm filaments in vitro were isolated from three different bovine tissues: the viable portion of the hoof epithelium, the epithelium of the esophagus, and cultured endothelial cells derived from aorta. The seven polypeptides from hoof, the two from esophagus, and the one from endothelial cells were different with respect to mobility in SDS polyacrylamide gels and/or limi...

Equine canker is a chronic pododermatitis of the hoof in horses. Although spirochetes are detectable histopathologically in the lesions, the precise etiology remains unclear. This study reports the 16S rRNA gene sequencing of randomly selected clones based on PCR with Treponema-specific primers, using the canker lesions from two horses and healthy frog and sole from a horse. A total of 114 clon...

The aim of the presented study was to estimate the influence of the traits of hoof measurement in dairy cows on claw disorders, lameness, and locomotion scores were determined. Data on claw health and measurement trait of claws were collected from 68 primiparous cows housed in tie stalls and from 76 primiparous cows housed in free stalls. Data were collected during professional claw trimming. T...

A five year-old bull moose (Alces alces) was culled due to chronic hoof overgrowth that required frequent intervention. Radiographic examination revealed changes in phalangeal bone structure usually considered indicative for laminitis in domestic cattle; similar changes were absent in the hooves of a free-ranging moose of similar age. The captive animal had been maintained in exhibits whose flo...

The Cooperative Extension Service offers its programs to all eligible persons regardless of race, color, national origin, religion, gender, age, disability, marital or veteran status, or any other legally protected status, and is an Affirmative Action/Equal Opportunity Employer. Laminitis is a painful lameness condition that can affect any breed of horse or pony. Although the exact mechanics of...
