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.

How to Detect DD in Pregnant Heifers

By Steve Mason on

Researchers at the University of Wisconsin reported that heifers with pre-partum digital dermatitis (DD) had lower milk production, poorer conception to first service, longer days open and were more likely to have multiple cases of DD. Those researchers recommended that a DD control program should be a priority for pregnant heifers. But before a control program can be implemented, a reliable method of detecting DD in these animals is required. At the 2016 Western Canadian Dairy Seminar, University of Calgary graduate student Casey Jacobs described how she used ‘pen walks’ to detect DD in pre-calf heifers.

Zinpro’s new Cattle Lameness book

By Steve Mason on

Zinpro has recently released a new book and app dealing with beef and dairy cattle hoof health. ‘Cattle Lameness: Identification, Prevention and Control of Claw Lesions’ is a Zinpro-led industry effort to assist cattle producers in improving animal wellness through the prevention of lameness.

How to treat non-healing claw lesions

By Steve Mason on

Non-healing (nh) bovine hoof horn lesions, characterized by penetration of the horn capsule and association with white line disease (nhWLD) and sole ulcers (nhSU) are frequently encountered in dairy herds endemically affected by digital dermatitis (DD). Lesions of this type are associated with more severe lameness, often leading to claw amputation or slaughter and they respond poorly to standard DD treatment. Researchers in Austria recently described a successful therapy for such lesions.
