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’

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.

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. A recent analysis of the cat claw (Homberger et al., in press) and horse hoof (Bragulla & Homberger, 2007) revealed that the ...

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 generated the temporal ...

Evaluation of a novel training course for hoof trimmers to participate in a Swiss national cattle claw health monitoring programme

Schweiz Arch Tierheilkd, 2021
The main goal of the resources project «Healthy claws - the foundation for the future» is to establish a Swiss national claw health monitoring programme for cattle, similar to what has already been established in other countries (e. g. Finland, Sweden).

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

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).

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.

Treecreeper Drone: Adaptive Mechanism for Passive Tree Trunk Perching

Advanced Intelligent Systems, EarlyView.
Taking inspiration from treecreepers, a passively triggered aerial robot that can reliably perch on vertical tree trunks is presented. The friction‐based approach combines a microspine array with a tail‐like support, and then validates via dynamic analyses and flight experiments, ensuring stable performance across trunk diameters and bark textures ...

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

The Anatomical Record, EarlyView.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...
