Claw horn lesions in dairy cows: does ketoprofen with therapeutic trimming improve mobility and recovery? — MAYBE (weak evidence) (the treatment made no difference)

In lame dairy cows with claw horn lesions, does ketoprofen vs trimming alone improve mobility scores and recovery time?

Shelf #879 · gate-verified and displayed under the developer's blinded-trial rule

MAYBE (weak evidence) (the treatment made no difference — scoped to the mobility/cure outcome for ketoprofen added to trimming alone): In the largest randomised trial carded (Thomas 2015; 167 newly lame cows with claw horn lesions on 5 farms, all therapeutically trimmed), the proportion sound (locomotion score 0) at 35 days was 12 of 42 (28.6%) with trim plus a 3-day ketoprofen course versus 11 of 45 (24.4%) with trim alone — no significant difference; the significantly better arm was trim plus block plus ketoprofen (23 of 41, 56.1%), a combined intervention this question does not isolate. In Whay 2005 (40 lame dairy cows, randomly assigned to ketoprofen or saline alongside conventional lesion treatment), locomotion scores improved in all cows with no significant ketoprofen effect, although ketoprofen did significantly modulate the hyperalgesia (nociceptive threshold) associated with lameness on days 3, 8 and 28. A small pilot (Janßen 2016; 11 ketoprofen vs 10 placebo acutely lame cows) likewise found no obvious effect of pre-emptive ketoprofen on stress responses to therapeutic trimming. Design class (a): randomisation and blinding are both established by carded records — Thomas 2015 states cows were 'randomly allocated' with the primary outcome scored 'by an observer blind to treatment group', and Janßen 2016 states cows were 'blinded and randomly assigned'. The honest limits: the ketoprofen-alone arms are modest in size, the positive Thomas arm confounds ketoprofen with the block, and the hyperalgesia benefit in Whay is a pain-threshold measure, not faster mobility recovery. The mobility claim therefore rests on null randomised evidence, graded MAYBE (weak evidence) with the null scoped as above.

Thomas 2015: trim plus ketoprofen alone cured 12 of 42 cows (28.6%) to sound at 35 days versus 11 of 45 (24.4%) for trim alone — not significant; only trim plus block plus ketoprofen (56.1%) beat trim alone

Randomized controlled trial (record's own wording: 'randomized controlled trial'; primary outcome scored by an observer blind to treatment group; publication type: Randomized Controlled Trial)

Who: Dairy cows: newly lame cows with a claw horn lesion (sole haemorrhage, sole ulcer or white line disease) on a single claw of a single foot, on 5 farms; cows had 2 nonlame locomotion scores followed by a lame score before enrolment. After a therapeutic trim, cows were randomly allocated to: trim only (positive control, n = 45 analysed), trim plus a block on the sound claw (n = 39), trim plus a 3-day course of ketoprofen (n = 42), or trim plus block plus ketoprofen (n = 41). The primary outcome was locomotion score 35 days after treatment, by an observer blind to treatment group.

Result: Cures to sound (locomotion score 0) at 35 days were 11 of 45 (24.4%) for trim only, 14 of 39 (35.9%) for trim plus block, 12 of 42 (28.6%) for trim plus ketoprofen, and 23 of 41 (56.1%) for trim plus block plus ketoprofen. Only the difference between trim plus block plus ketoprofen and trim only was significant, including in logistic regression models for sound and nonlame outcomes adjusted for farm, season, lesion, limb, operator and stage of lactation. Ketoprofen added to trimming alone did not significantly improve cure.

Watch out: The one significant arm combines two interventions (block plus ketoprofen), so it cannot be credited to ketoprofen alone — and this shelf's question is ketoprofen versus trimming alone. Cows were newly and predominantly mildly lame; results may not extend to severe or chronic lesions.

Whay 2005: ketoprofen did not significantly change locomotion-score improvement in 40 lame cows, but significantly modulated lameness-associated hyperalgesia on days 3, 8 and 28

Randomised controlled study (record's own wording: cows 'randomly assigned'; MeSH includes Random Allocation; blinding not stated in the record)

Who: Dairy cows: 40 lame dairy cows receiving conventional treatment for their lameness lesions, randomly assigned to a course of ketoprofen or sterile saline. Locomotion scoring and nociceptive threshold (hyperalgesia) testing were performed over 28 days.

Result: The locomotion score of all cows improved, but ketoprofen had no significant effect on that change. In the ketoprofen cows, the hyperalgesia associated with lameness, measured by nociceptive threshold testing, was significantly modulated on days 3, 8 and 28 after initial examination, drug administration and lesion treatment.

Watch out: The positive finding is a pain-threshold test, not a mobility or recovery-time outcome — a cow can be less hyperalgesic without walking or recovering measurably better. No effect sizes for the threshold change are given in the abstract, and blinding is not stated in this record.

Janßen 2016: pre-emptive ketoprofen showed no obvious effect on hormonal, metabolic or behavioural stress responses to therapeutic claw trimming in 21 acutely lame cows

Pilot randomised study (record's own wording: cows 'blinded and randomly assigned'; publication type: Journal Article)

Who: Dairy cows: 21 acutely lame cows with non-advanced claw horn lesions (sole ulcers or white line disease) undergoing therapeutic claw trimming in lateral recumbency, blinded and randomly assigned 15 minutes before intervention to ketoprofen (n = 11; 3 mg/kg body weight intramuscularly) or placebo saline (n = 10); 21 matched nonlame cows undergoing regular trimming served as controls. Blood and faecal stress markers and leg movements during trimming were recorded.

Result: Concentrations of blood cortisol, fatty acids, glucose and faecal cortisol metabolites were higher in lame than in nonlame cows after treatment, and more leg movements were recorded in lame cows during treatment. Pre-emptive administration of ketoprofen had no obvious effects on the stress responses to therapeutic claw trimming. The authors conclude that treating claw horn lesions causes a significant stress and pain reaction in acutely lame cows, demonstrating the need for adequate pain management protocols.

Watch out: A pilot of 21 lame cows measuring stress physiology around a single trimming event — it does not measure mobility recovery over days to weeks, and 'no obvious effects' in a pilot cannot exclude a modest effect. Carded as a consistent counterweight, not as decisive evidence.

Synthesis: ketoprofen added to trimming alone has not been shown to improve mobility or recovery in claw horn lesion lameness — MAYBE (weak evidence) (the treatment made no difference on the mobility outcome)

Synthesis

Who: Synthesis of the cards above: Thomas 2015 (randomised trial, 167 newly lame cows with claw horn lesions on 5 farms, blinded outcome scoring), Whay 2005 (randomised study, 40 lame cows, locomotion and nociceptive thresholds over 28 days) and Janßen 2016 (pilot, 21 acutely lame cows, stress responses to trimming).

Result: (1) Mobility cure at 35 days: 28.6% (12/42) with trim plus ketoprofen versus 24.4% (11/45) with trim alone — not significant (Thomas). (2) Locomotion improvement over 28 days: no significant ketoprofen effect (Whay). (3) The signals that do favour ketoprofen are a pain-threshold measure (Whay) and a combined block-plus-ketoprofen arm (Thomas, 56.1% sound) that cannot isolate the drug. On the question as asked — ketoprofen versus trimming alone for mobility and recovery — the randomised evidence is null, supporting MAYBE (weak evidence) with the null suffix scoped to that outcome.

Watch out: This shelf does not answer whether trim plus block plus ketoprofen beats trim alone (Thomas suggests it does), whether ketoprofen helps other lameness causes such as digital dermatitis, or whether longer NSAID courses differ — those are separate questions with their own homes or none yet. Later large trials of routine ketoprofen at calving and lameness events (a prevention/long-horizon question) are not carded here and do not change this treatment question's null result.
