Claw Characteristics of Culled Sows from Three Farrow-to-Finish Greek Farms. Part 2: Mechanical Indices of Hoof Horn and Their Associations with Length Measurements and Lesion Scores [PDF]
Veterinary Sciences, 2021 The objective of the present study was to investigate the mechanical indices of hoof horn and their association with length measurements and lesion score. The feet of 185 culled sows from three Greek farms (A: 57 sows; B: 64 sows; C: 64 sows) were used. A slice from the dorsal wall of each claw was used to assess by a three-point bending test the Young’

Role of Hoxc genes in the development of the limb integumentary organ (nail, claw, or hoof)
The FASEB Journal, 2018 The developing vertebrate limb has long proved as an excellent system for studying the mechanisms involved in pattern formation and morphogenesis and more recently in transcriptional regulation and morphological evolution. To elucidate the stage‐specific expression profiles of the components of the developing limb, we have ...

Survey of Veterinarians and Hoof Trimmers on Methods Applied to Treat Claw Lesions in Dairy Cattle
, 2005 A survey inquiring about treatment approaches for claw horn lesion in dairy cattle was available to veterinarians and hoof trimmers who were members of either the American Association of Bovine Practitioners (AABP) or the Hoof Trimmers Association (HTA) during the winter of 2013.

Changes in Claw Shape and Load after Hoof Trimming in Dairy Cattle Housed in a Free Stall System
Nihon Chikusan Gakkaiho, 2005 乾乳期間中の乳牛49頭（初産19頭，2産14頭，3産以上16頭）に対して，分娩前2ヵ月で削蹄を行い，以降1ヵ月間隔で4ヵ月間に渡り前・後肢蹄形状，蹄角質硬度および蹄球糜爛スコアを調査した．供試牛は乾乳期間中には屋外パドック，分娩後1週からはフリーストール牛舎で飼養されていた．また，削蹄直後と削蹄後4ヵ月では前・後肢内・外蹄荷重を計測した．削蹄後2ヵ月で後肢外蹄蹄踵高が有意（P＜0.05）に増加，前・後肢内蹄蹄尖角度が有意（P＜0.05）に減少し，削蹄後3～4ヵ月で外蹄に対する内蹄負面面積の割合は後肢では有意（P＜0.05）に減少したが，前肢では有意な変化は認められなかった．削蹄後4ヵ月で外蹄に対する内蹄の荷重割合は後肢では有意（P＜0.05）に減少し，前肢では有意（P＜0.05）に増加した ...

Footrot in Clawed and Hoofed Animals: Symptoms, Causes and Treatments
Biotechnology & Biotechnological Equipment, 2013 Footrot is a chronic bacterial infection in cattle, horses, pigs, deer and mouflons. The disease leads to huge economical losses in the wool, meat and dairy industry. Although Dichelobacter nodosus is considered the essential transmitter of the disease, a complex synergism exists with Fusobacterium necrophorum.

Gradual Growth of Several Claw Traits and Claw Lesions in Dairy Cows after Hoof Trimming
Open Access Journal of Veterinary Science & Research, 2022 Several claw measurements, horn growth and wear were recorded monthly in a research farm to investigate the effect of solid concrete floor and gradual growth of these traits over 3 month after trimming. Two methods of hoof trimming were used: Standard Dutch (STD) and hollow (HOL).

A comparative analysis of the cat claw, horse hoof, and human fingernail
The FASEB Journal, 2009 Earlier authors (e.g., Boas, 1931) have tried to homologize the skin modifications in mammalian cornified digital end organs (claws, hooves, and nails), but have considered only major parts, such as the wall and sole.

Partial substitution, with their chelated complexes, of the inorganic zinc, copper and manganese in sow diets reduced the laminitic lesions in the claws and improved the morphometric characteristics of the hoof horn of sows from three Greek herds [PDF]
Porcine Health Management, 2016 Hoof lesions in sows have been associated with lameness and poor hoof horn quality. The mechanical strength and quality of hoof horn is determined by the density and diameter of horn tubules, which were recently associated with the severity of lesions on the hoof wall of sows.

The Master Hoof (Claw) Care Program: Summary Statistics From Three Years
EDIS, 1969 In 1996, through a grant from the Florida dairy farmers, the Master Hoof Care Program was developed at the University of Florida. The objective of this program was (and is) to train dairy health care technicians and others in proper methods of foot care and claw trimming. The program is offered three times per year at the University of Florida and once
