The properties of the suspensory and supporting structures of the bovine claw are of particular importance in the pathogenesis of claw lesions since both must function optimally to prevent soft tissue compression and trauma. An essential component is the shock-absorbing digital cushion situated under the distal phalanx. The sound claws of 54 slaughtered(More)
The mural suspensory apparatus of third phalanx and its supportive heel cushion were examined in 19 cows with an ulcer at the 'typical' site (Rusterholz ulcer) to gain information on the pathogenesis of sole and heel ulcers. The claws of 17 healthy controls were used for comparison. The left hind claws, frozen at -20 degrees C, were sectioned in one(More)
The pads of the bovine digital cushion, which serves as a shock absorber, have specific anatomical structures to cope with the substantial forces acting within the claw. To gain more information on the lipid composition and content of the pads, horn shoes from 12 slaughtered heifers and cows were removed and different samples of the pads excised with a(More)
REASONS FOR PERFORMING STUDY The diagnosis of lameness caused by proximal metacarpal and metatarsal pain can be challenging. Magnetic resonance imaging (MRI) offers the possibility for further diagnosis but there have been no studies on the normal MRI appearance of the origin of the suspensory ligament (OSL) in conjunction with ultrasonography and(More)
The objective of this study was to investigate the influence of orally administered biotin on the healing of uncomplicated sole ulcers in dairy cattle. In a double-blind controlled study, 24 dairy cows with a mild, uncomplicated sole ulcer on a lateral hind claw were given either 40 mg biotin per day or a placebo feed over a period of 50 days. An(More)
The aim of the present study was to determine ultrasonographically the size of the umbilical structures in clinically health newborn calves and to evaluate their involution during the first three weeks of life. A total of 13 ultrasonograms were obtained in each of 20 healthy newborn calves using a 7.5-Mhz sector scanner transducer placed across the linea(More)
Measurements were taken in the metacarpal and metatarsal bones in 42 calves and 10 dairy cows post-mortem to determine whether there are anatomical differences in bone length. Manual and digital measurements of various bone length parameters were taken. There was a significant difference in the mean length of the condyles of the metacarpal and the(More)
Radiography of the equine hoof is often used to obtain a diagnosis. Quantitative interpretation, especially for research purposes requires high quality and accuracy of radiographs. The purpose of this study was to describe and evaluate a radiographic technique for the lateromedial (LM) and the dorsopalmar (DP) view of the equine hoof. Ten radiographs for(More)
