The association of hoof lesions at claw trimming with test-day milk yield in Danish Holsteins
Preventive Veterinary Medicine, 2007In a cross-sectional study, performed between October 2002 and April 2003 on 55 Danish dairy herds with 6161 predominantly Holstein Friesian cows the prevalence of 9 hoof lesions was determined. All test-day yields (TDY) of kg energy corrected milk (ECM) in the lactation of diagnosis were recorded.

Survey of veterinarians and hoof trimmers on methods applied to treat claw lesions in dairy cattle
The Bovine Practitioner, 2013A survey was administered to members of the American Association of Bovine Practitioners (AABP) and the Hoof Trimmers Association (HTA) to identify various treatment methods for claw horn lesions. A total of 345 people responded to the survey, of which 196 identified themselves as members of AABP, 111 as members of HTA, 9 as having membership in both ...

Equine Veterinary Journal, 1985
SummaryAn in vitro method has been designed and used to study the incorporation of 75Se‐cystine into matrix fragments from hooves and claws of healthy horses and cattle. Tissue fragments from the zone of keratinisation were incubated with L‐75Se‐cystine in a tissue culture medium for 4 to 6 h, during which time there was continuous incorporation of the

Abstract Objectives To determine contribution of the wall segment of bovine cattle hoof to horn production, and relevance of structural differences of the wall segment and its horn production rate to claw disease. Design Epidermis and papillary body of the wall segment were examined by mesoscopy, light microscopy, and transmission and scanning ...

Nail, Claw, Hoof and Horn Keratin
1986Most land mammals produce in addition to hair another form of hard keratin — nail, claw or hoof — and occasionally a third form, either horn or quill. Although the so-called horny keratins — nail, claw, hoof, horn and quill — are similar to hair in ultrastructure and composition, their functions are very different.

Computerised claw trimming database programs as the basis for monitoring hoof health in dairy herds
The Veterinary Journal, 2013Regular documentation and recording of udder health, reproduction and metabolic status are common practices on dairy farms. However, recording of claw health is less commonly undertaken. Computerised claw trimming documentation and analysis programs have been developed in Germany, Denmark, The Netherlands, United Kingdom, Spain, United States, and ...

Hair, Wool, Quill, Nail, Claw, Hoof, and Horn
1986Mammalian hair, wool, quill, nail, claw, hoof and horn are epidermal derivatives and all, like the stratum corneum of epidermis, give an α X-ray diffraction pattern. But, unlike str. corneum, which is a soft keratin, the above derivatives are hard keratins.

Elastic properties of hoof horn on different positions in the bovine claw.
DTW. Deutsche tierarztliche Wochenschrift, 2005Hind claws of 15 adult, sound Fleckvieh cows were used for material analysis. The elastic modulus was tested in tension tests according to EN ISO 527 and ASTM D 638-03 at a universal material testing machine. Samples were taken from different segments of the bovine claw to find the differences in material properties. Samples orientation was parallel to

Zur mikroskopischen Anatomie der Epidermis an der Schweineklaue
Anatomia, Histologia, Embryologia: Journal of Veterinary Medicine Series C, 1980To gain a basis for diagnosing the frequent pathological changes of the porcine hoof, the fine structure of normal hoofs taken from landrace pigs was examined with the light microscope, the polarizing microscope and the electron microscope. The hoofs were taken mostly from 6 to 7 month-old slaughtered pigs, but also from younger animals, beginning at ...
