Dr. Dörte Döpfer at the University of Wisconsin, describes the dynamics of digital dermatitis infection as a cycle with 6 distinct stages.
Twenty-five professional hoof trimmers recorded hoof lesion occurrence in over 80,000 cows during regular trimming visits to 578 dairy farms in Alberta, British Columbia and Ontario. Digital dermatitis and claw horn disruption accounted for 84% of all lesions observed.
A short video clip illustrating slow motion gait analysis reveals how walking on hard surfaces causes trauma to the claw leading to sole hemorrhage, white line lesions and sole ulcers.
Sole ulcers are among the most common causes of lameness in dairy cattle. Why are they so common?
Accurately identifying specific lesions is critical for treatment and prevention plans. This article provides standardized names, abbreviations, descriptions and photos of the 14 claw lesions agreed upon by the International Bovine Lameness Committee.
Although feeding and management have the most important short-term impact on hoof health, the role of genetics, although a longer-term influence, cannot be overlooked. Sweden has promoted breeding for healthy cows, maintaining high production for several decades. In 2006, a breeding value for claw health based on data recorded by hoof trimmers started to be included in the health profile.
Laminitis refers to a condition that impairs the circulation in the horn-producing tissues of the foot (corium). The disease results in the hoof producing poor-quality horn, which leads to increased injury from concussion and other causes.
A study conducted on 18 Dutch dairy farms provides insight into how footbaths can go wrong.
‘Bovine Laminitis and Lameness’ describes the anatomy of the bovine hoof and claw and the causes of lameness, including the importance of genetics, structural conformation of the leg and hoof, nutrition, management, cow comfort and facilities that minimize injuries.
Digital Dermatitis (DD), also known as Hairy Foot Warts, Strawberry Foot Rot, Mortellaro’s Disease and Rasperry Heel, has become the most prevalent infectious hoof disorder on many dairy farms. Dr. Paul Greenough, in his book ‘Bovine Laminitis and Lameness’ recommends treatment for animals infected with DD.
