Surface strains were recorded from four rosette gauges at different sites on the right forehooves of three ponies running on a treadmill at seven constant speeds and using three gaits. Principal strains determined from the rosette signals indicate that the hoof material is loaded predominantly in compression and that the wall is distorted in a regular, repeatable manner at all speeds and gaits....

Twelve healthy, adult donkeys of both sexes aged between 2 and 4 years were used to evaluate the feasibility of using coronary band autografts to aid in the healing of deep dermal hoof wall injuries. Wound healing and graft take were monitored visually and evaluated histologically at different time points. Epidermal cells of the coronary papillae survived the process of hoof wall stripping. Alm...

The connection between a feeding regime with a high proportion of concentrates and laminitis is well recognized in domestic animal medicine but has received little attention in captive wild hoofstock. We used the occasion of a transport of two ruminant groups, that necessitated immobilization, for an evaluation of the appearance of the hooves on the one, and of the pH of the rumen fluid gained ...

The internal, anatomical disintegration of the hoof, which accompanies the acute episode, is initially, invisible to the naked eye. With the passage of time however the hoof begins to display the effects wrought upon on it by the pathology of the acute phase. If the initial lamellar pathology is mild the clinical signs of laminitis may abate as the distal phalanx lamellar attachment apparatus r...

Cattle hoof meal was processed by autoclaving, fermentation, wood ash soda treatment and rawunprocessed hoof. This studied on Clarias gariepinus juveniles 14.22±0.23g stocked at 15 fish per tank in replicate. Treated samples were used compounding six isonitrogenous diets of a reference diet 70%: test 30% fed 3% body weight. Significant difference (P<0.05) observed among dietary treatments. W...

This case report shows that keratomas can occur in both hind feet of equine patients and should be considered as a diagnosis for long-standing, intermittent lameness localised to the hooves. A Thoroughbred racehorse presented with long-standing abscessation of the right hind hoof. Owing to the long-standing nature, the abscess draining tract was surgically explored. A focal mass was found withi...

To evaluate the effects of chelated Zn/Cu/Mn on redox status, immune responses and hoof health in lactating Holstein cows, 48 head in early lactation were divided into healthy or lame groups according to their gait score. Cows were fed the same amount of Zn/Cu/Mn as sulfate salts or in chelated forms for 180 days, and foot-and-mouth disease (FMD) vaccine was injected at day 90. The results show...

Serum level of zinc, copper, β-carotene, vitamin A, and concentrations of Zn and Cu in hoof of 97multiparous Holstein dairy cows with different locomotion scores (LSs) were evaluated. Simultaneously, Znand Cu concentrations of close up, fresh and high yielding cattle rations were 77, 94, 75 and 31, 28, 22 ppm, respectively. Based on LSs, despite normal serum copper levels in all three groups, w...

Delineating the factors that orchestrate keratinocyte growth and differentiation in the claw is pivotal to understanding the quality of hoof horn production in health and disease. The specific objectives of this investigation were to establish an in vitro culture system for bovine coronary region keratinocytes and dermal fibroblasts, determine the colony-forming capacity of epidermal keratinocy...

Papillomatous digital dermatitis (PDD) is a polymicrobial infection in soft tissue adjacent to the hoof and is the leading cause of lameness in dairy cattle. Treponema phagedenis-like (TPL) spirochetes are a constant feature of PDD lesions and are localized deep in infected tissue. Host-cell response mechanisms to TPL spirochetes are poorly understood. To assess how bovine macrophages respond t...
