Lameness Risks on Alberta Dairy Farms

By Laura Solano on

Alberta’s Lameness Reduction Initiative (LRI) was designed to identify housing and management factors that contribute to the development of hoof lesions. The LRI provided an opportunity to improve collaboration, knowledge and communication between farmers, advisors and veterinarians and for each farm to identify weaknesses and design targeted management and facility changes.

Lower DD prevalence in high immunity cows

By Steve Mason on

Researchers at the University of Guelph reported the results of a study designed to evaluate whether the ability of dairy cows to mount an immune response could be related to susceptibility to digital dermatitis (DD) infection. They showed that cows demonstrating a strong antibody-mediated response to an intramuscular antigen challenge had a lower prevalence of DD than cows showing an average or weaker response.

Best management practices for footbathing

By Steve Mason on

Nigel Cook recently reviewed current footbath practices used in dairy herds, questioned the mechanism by which footbaths function, and reviewed the available scientific literature for guidelines to assist in the creation of best practices for their use. Based on that review, a summary of his recommendations for footbath design and management is presented.

Sara Pedersen’s Recommended DD Treatment Strategy

By Steve Mason on

Sara Pedersen, a prominent UK veterinary consultant who specializes in hoof health, presented her recommendations for digital dermatitis (DD) control at the recent UK Cattle Lameness Conference. Her ‘blitz’ treatment approach is designed to break the cycle of environmental contamination of the bacteria that cause DD, recognizing that these Treponemes only survive in slurry for up to 24 hours.

Early DD Detection and Treatment

By Steve Mason on

Prevention of DD focuses on biosecurity, maintaining good barn hygiene and routine foot bathing. Treatment of DD infections is typically only done by hoof trimmers at their infrequent visits—usually by applying antibiotic and bandaging for a few days. But, because new infections can rapidly advance, early detection and treatment is necessary to minimize new outbreaks of active lesions.
Over the past few years, researchers at the University of Calgary’s Faculty of Veterinary Medicine have been working to develop a practical way to routinely identify and treat painful DD lesions in the milking parlour.

How one veterinarian works with dairy herds to control lameness

By Nigel Cook on

When troubleshooting lameness problems, I use a structured approach starting with locomotion scoring, lesion analysis and assessment of the routine hoof-trimming and lame cow surveillance program. I then examine the risk factors for each of the key hoof lesions and finish with a review of feeding practices. From this examination, we can create a herd specific action plan designed to maximize impact on the key hoof lesions on the farm.
