Concrete floor-bovine claw contact pressures related to floor roughness and deformation of the claw.
The intention of this research was to study the impact of concrete floor surface roughness on a bovine claw model and to assess the deformation of the bovine claw model under load. The pressure distribution between the floor and the claw is the key method in this research. Monitoring foot-to-ground pressure distributions may provide insight into the relation between high local pressures and foo...
متن کاملEvidence-based claw trimming for dairy cattle.
Claw trimming every four to six months has become a routine procedure for the majority of high yielding housed dairy cows. Various methods have been described, but the Dutch Five Step method (Toussaint Raven 1985) is probably the most widely used approach around the world and has been the basis for most research. Despite being the most commonly used protocol internationally, the Dutch Five Step...
متن کاملReduced test-day milk fat percentage in cows diagnosed with claw horn lesions during routine claw trimming.
The objective of this study was to investigate whether cows diagnosed with claw horn lesions during routine claw trimming had an altered milk fat percentage on test days preceding the diagnosis, compared with cows without such lesions. Data included date of trimming, cow number, type, and location of claw lesions recorded by a professional claw trimmer during routine trimming sessions on 11 com...
متن کاملClaw and limb disorders in 12 Norwegian beef-cow herds
BACKGROUND The main aim of the study was to assess the prevalence of claw and limb disorders in Norwegian beef-cow herds. METHODS Twenty-six herds with >or=15 cow-years were selected by computerized systematic assignment from the three most beef cattle-dense regions of Norway. The study population consisted of 12 herds with 28 heifers and 334 cows. The animals were trimmed and examined once b...
متن کاملRelationship between herd-level incidence rate of energy-related postpartum diseases, general risk factors and claw lesions in individual dairy cows recorded at maintenance claw trimming
BACKGROUND Laminitis and energy-related postpartum diseases share several risk factors, indicating a common etiology. Thus, a herd's incidence rate of energy-related postpartum diseases, such as displaced abomasum and clinical ketosis, might reflect the likelihood of cows to suffer from laminitis-related claw lesions. The aim of this study was to investigate the association between herd-level i...
