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.

What Canadian Cows Are Telling Us about Footbaths

By Karin Orsel on

The University of Calgary Lameness Research Team has been hard at work studying the use and effectiveness of footbaths on Alberta dairies.
While there is progress to be made in proper usage, the good news is: Results confirm that footbaths are an effective tool in decreasing the prevalence of digital dermatitis (DD).

Three Steps to Zero Lameness

By Jamie Sullivan on

I’ve been in the hoof care business for more than 22 years and the dairy industry all my life, and I believe farms think they are doing all they can to provide the environments for optimal animal welfare and comfort; however, the reality is: Our industry lameness average is still too high – estimated at 25 to 40 percent, depending on which study you want to quote.

Many believe that 0 percent lameness is not a possible or a realistic goal, but I am challenging every dairy to have more days with no lame cows than days with a cow with lameness issues. In this article, I propose a straight-forward three-step strategy to achieve zero lameness.

A 5-point plan for DD Control

By Steve Mason on

A comprehensive strategy for the control of digital dermatitis (DD) in dairy herds was presented at the 2016 UK Cattle Lameness Conference. The 5-point plan, which applies to young stock as well as dry and lactating cows, includes:
1. External biosecurity to keep disease out of farm
2. Internal biosecurity to minimise infection pressure on cows
3. Early identification, recording and treatment of clinical cases, in
association with hoof care
4. Frequent foot disinfection to reduce new cases
5. Defining and monitoring hoof health targets

Lameness Risk Factors in Robot Herds

By Steve Mason on

Results of a study of 36 herds with automated milking systems in Québec, Ontario, Alberta and Michigan identified some of the main risk factors for lameness in those herds. The authors of the study conclude that, for the prevention of lameness, more attention needs to be be paid to providing free stalls of appropriate size for the cows in the herd.

Digital dermatitis lesions are easy to detect in the milking parlour

DD Detection in the Milking Parlour

By Steve Mason on

To control digital dermatitis (DD), M2-stage lesions need to be treated as soon as possible after they are detected. Waiting more than a few days for the next time the trimmer is scheduled to visit will never get DD under control. Several studies have examined the accuracy of DD detection in the milking parlour compared with lifting feet in a trim chute. Results suggest that inspection of heels in the parlour using a simple mirror and headlamp is a viable option for routinely monitoring DD lesions.
