A Veterinarian’s View of Foot Bathing for DD Control

By Louise Hartley on

With digital dermatitis (DD) now being implicated in non-healing hoof lesions, its control is becoming more important than ever. Footbathing remains the key way of controlling DD infections on-farm, according to British veterinarian Sara Pedersen who says:

“Digital dermatitis is often described as ‘mastitis of the foot’, so foot bathing can be considered the equivalent to teat dipping in mastitis control. It can also help harden the hoof and make it less susceptible to penetrating injuries or shearing forces.”

Milk Residues and Tetracycline Use

By Peggy Coffeen on

The threat of tetracycline residues ending up in the bulk tank is one for dairy producers to take seriously. While the legal limit for the drug in milk is 300 ppb in the U.S. and 100 ppb in Canada, there are processors running tests that can detect as little as 10 to 30 ppb – and by some of their standards, that could mean rejecting a load of milk.

An alternative treatment for thin soles

By Steve Mason on

There are 2 main causes of thin soles in dairy cattle:
1. an abrasive floor, particularly a new one in a barn cows have recently moved into;
2. excessive hoof trimming.

Without immediate intervention, some cows will completely lose the sole horn and the underlying corium, which is especially thin at the tip of the toe, will be uncovered. Therefore this area is very vulnerable for ascending infections. An alternative treatment for cattle with thin soles was presented at the recent Lameness Conference in Bristol UK.

Digital Cushion Depth Affects Susceptibility to Claw Horn Lesions

By Steve Mason on

A study by researchers at Cornell University examined the association between claw horn lesions and the thickness of the digital cushion. Results suggest that thin digital cushions, related to low body condition score, may be a factor in the development of sole ulcers and white line lesions.

Can Gait Scoring Identify Cows with Hoof Lesions?

By Steve Mason on

To investigate the association between locomotion score and the presence of hoof lesions, researchers examined 10,699 cows from 91 dairy herds in southern Chile. Locomotion score was recorded on a scale of 1-5 using the Sprecher system. Lesions were recorded by observation of all four feet with each cow standing in a metal crush. Locomotion scoring was a relatively insensitive method for the detection of some important claw lesions.
