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...

claw capsule lesions are the most common cause’s lameness in cows. during the entire year of 2005 a survey was undertaken by sir author on the prevalence of different claw lesions causing lameness on 30882 cases of culled cows and bulls at central abttoir in the vicinity of ardebil which was well equiped and with new constructions. after recording information for each case, the feet were amputa...

BACKGROUND 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. Histologic changes that have previously been described in cases of bovine laminitis, have also been observed...

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...

Digital dermatitis is a major problem in modern dairy production because of decreased animal welfare and financial losses. Individual cow treatments are often seen as too time consuming by farmers, and walk-through hoof baths have therefore been used extensively to control digital dermatitis. For decades, copper sulfate hoof baths have been used to treat and prevent digital dermatitis. Copper s...

The eigenfrequency of a resonator plays a significant role in the operation of a cylindrical shell vibrating gyroscope, and trimming is aimed at eliminating the frequency split that is the difference of eigenfrequency between two work modes. In this paper, the effects on eigenfrequency under resonator-top trimming methods that trim the top of the resonator wall are investigated by simulation an...

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...
