In a cross-sectional study, performed between October 2002 and April 2003 on 55 Danishdairy herds with 6161 predominantly Holstein Friesian cows the prevalence of 9 hoof lesionswas determined.All test day yields (TDY) of kg Energy Corrected Milk (ECM) in the lactation of diagnosiswere recorded. For the purpose of including hoof lesions in a decision support model anattempt w...

The purpose of this study was to report the use and assess the effects of extracorporeal shockwave therapy (ESWT) for the treatment of carpal joint valgus deformities (CJVDs) in young foals. Only foals with CJVDs greater than 5 ̊ were included in the study. Foals were assigned to 3 treatment groups based on their degree of CJVD measured during the initial evaluation: valgus deformity (VD) of 5 ̊ ...

Cattle handling is a dangerous activity on dairy farms, and cows are a major cause of injuries to livestock handlers. Even if dairy cows are generally tranquil and docile, when situations occur that they perceive or remember as aversive, they may become agitated and hazardous to handle. This study aimed to compare human-animal interactions, cow behavior, and handler safety when moving cows to d...

INTRODUCTION Ground reaction forces in sound horses with asymmetric hooves show systematic differences in the horizontal braking force and relative timing of break-over. The Center Of Pressure (COP) path quantifies the dynamic load distribution under the hoof in a moving horse. The objective was to test whether anatomical asymmetry, quantified by the difference in dorsal wall angle between the ...

The hoof digital cushion is a complex structure composed of adipose tissue beneath the distal phalanx, i.e. axial, middle and abaxial fat pad. The major role of these fat depots is dampening compression of the corium underneath the cushion. The study aimed to determine expression of target genes and fatty acid profiles in the hoof of non-pregnant dry Holstein cows fed low (CON) or high-energy (...

REASONS FOR PERFORMING STUDY Sandy beaches are often considered good training surfaces for trotter horses. However, their biomechanical effects on locomotion are insufficiently documented. Events at hoof impact have mostly been studied under laboratory conditions with accelerometers, but there is lack of data (acceleration, force, movement) on events occurring under every day practical conditio...

Foot imbalance is believed to be a common cause of musculoskeletal injury in the horse; its biomechanical effects are, however, poorly understood. Wedges (angle 3.7 and 5 degrees) were attached to modified shoes to elevate one aspect of both front feet of Thoroughbred-type horses. The point of force application during weightbearing was determined at trot using a forceplate system. A total of 8 ...

ABSTRACT We present preliminary results of a bench-scale simulation of the mechanics of dust emissions from a cattle feedyard surface. The experimental apparatus simulated hoof action by dropping steel weights of standardized geometry onto an uncompacted layer of dried, sieved feedyard manure, varying the kinetic energy of the falling weight by adjusting the height from which it was dropped. Th...
