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.

How to Judge a Hoof Trim

By Steve Mason on

While a good hoof trimming program is an essential component of lameness prevention, poor trimming technique can create lameness. The Lameness Committee of the American Association of Bovine Practitioners (AABP) has produced a fact sheet aimed at helping veterinarians and producers to objectively assess a herd hoof trimming program.

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.

Hoof Trimmer – DHI Data Exchange: An Update

By Steve Mason on

The adoption of a standardized, computer-based system for recording hoof trimming data (Hoof Supervisor® – HS) has made it possible to collect and analyse that data for application in herd benchmarking and genetic improvement. To that end, a Canadian research project is in progress to develop a process for data interchange between HS-equipped trimmers and the national Dairy Herd Improvement (DHI) database and on to the Canadian Dairy Network, the national dairy genetics organization. The ability of trimmers to download DHI data in advance of a herd visit will also aid in the selection of cows to trim.

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.
