Can breeding improve hoof health?

By Steve Mason on

Although housing and management practices play a dominant role in dairy cattle hoof health, genetics can influence the incidence and severity of lesions. A preliminary analysis of hoof lesion data collected in 3 Canadian provinces suggests that it may be possible to use this type of data in genetic selection. A project is currently underway to investigate the possibility of incorporating data collected electronically by hoof trimmers into the Canadian national DHI database. This would facilitate the collection of the large quantities of data required to accurately calculate breeding values for hoof health traits.

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.

DD Treatments That Work

By Steve Mason on

Few claims about the efficacy of products used to treat digital dermatitis (DD) are supported by any conclusive scientific evidence. Not all treatment trials provide conclusive evidence – many reported trials are poorly designed, leading to bias towards a particular outcome.
A recent study considered a large number of DD treatment trials, eliminating all but four that were rigorously designed to give conclusive, unbiased results.
