Claw Horn Lameness

Claw -Horn _2017-11-03

Example Scenario:
Farm E is a 200-cow dairy farm producing 9,000 litres of milk per cow each year.

The herd manager has noticed a lot of lame cows with sole ulcers. There are 10 cows that are severely lame, all of which have sole ulcers when examined.

Example treatment options

Option 1 – Inappropriate use
Trim the cows feet and treat them with three days of Tylosin, an injectable macrolide.

This approach uses 2.1mg/PCU per treatment with a 3-day withdrawal. There is no evidence that antibiotics will improve the cure rates of non-complicated sole ulcers.

Option 2 – Improved approach
Treat the cows with a foot trim, block and non-steroidal anti-inflammatory drug (NSAID).

This treatment approach uses no antibiotic. Blocks and NSAIDs have been shown to improve outcomes in cows with claw horn disease.

Option 3 – Best practice
In addition to Option 2, fortnightly mobility scoring is used to identify and then treat early cases of lameness.

This approach uses no antibiotic in the short term and also results in treating cases sooner, increasing their chances of recovery and reducing the number of lame cows overall.
