Sioned TimothyMerial is highlighting the results of an independent study published in July's Journal of Dairy Science which showed that treating acutely lame cows with the non-steroidal anti-inflammatory (NSAID) Ketofen (ketoprofen), alongside therapeutic trimming and the application of a block, resulted in a significantly better recovery rate compared to the other treatment protocols used.

In the study, Evaluation of treatments for claw horn lesions in dairy cows in a randomised controlled trial by Thomas et al1, 56% of the cows in the above treatment group were observed to be sound. 

Sioned Timothy, Merial Technical Veterinary Manager (pictured right) said: "The lack of evidence to underpin a standardised approach to treating lameness in cattle has previously been highlighted2. 

"This study demonstrates the value of using an NSAID as part of lameness treatment both for its welfare benefits, and also to reduce the impact of lameness on herd productivity through improved recovery rates. It also highlights the importance of implementing herd health protocols that focus on early intervention – identifying cows as soon as they become lame should be a priority for dairy farmers. With lameness cited as having a significant adverse effect on milk yield3 and cull rate in the herd, a proactive approach to lameness control is critical. Farmers should work with their vets and foot trimmers to ensure that when lame cows are identified they are treated in the most effective way.”

Sioned added: "The importance of routine mobility scoring cannot be underestimated. Clinical lameness has been shown to cause a decreased milk yield from up to four months before diagnosis 3, which can translate to a mean reduction of 357 litres per 305 day lactation. Furthermore, the impact on fertility and the long term impact on replacement is also acknowledged, with lame cows less likely to conceive and having an increased risk of conception failing."
