Reducing Lameness in NZ dairy cattle

Lameness has health, productivity and wellbeing implications for dairy farms globally. Lameness is painful for the cow and has the potential to reduce the overall lifetime performance of dairy cows due to milk production loss, reduced reproductive performance and culling. The financial impact of lameness in NZ is estimated at $250 per lameness case or $15,000 per year (assuming an average herd size of 420 cows with an incidence of 14%).1  However, if individual farm data is entered into the lameness cost calculator estimates are in the order of $500 or more per lameness case, and this will be a more realistic figure as this tool takes into account the longer-term impacts of lameness, milk production loss, reduced reproductive performance and culling.

Lameness is most commonly observed around mating (i.e. November in NZ), with a second peak in late summer. Claw horn lesions (white line and sole disease) account for 80% of the lameness in NZ dairy cows. The greatest period of risk for these lesions developing starts at least 2 weeks before calving and lasts for at least 12 weeks after calving.

Around calving the fat pad becomes thinner and the ligaments inside the hoof relax. This makes the corium (soft tissue within the hoof) more susceptible to damage, known as the calving effect. The calving effect combined with other cow, management and environmental risk factors increase the risk of lameness. If lameness is left untreated, inflammation of the corium can result in permanent changes in the hoof structure increasing the likelihood of future lameness.

We know that early detection (MONITOR) and prompt effective treatment (MANAGE) with a trim, block and 3 days of KetoMax 15% achieves better outcomes for lame cows – including pain relief, faster recovery, improved reproductive performance, less culling and less future lameness (MINIMISE).5,6,7,8 Better for the cow, better for the farmer and better for NZ Inc.

The latest thinking in reducing lameness in dairy herds:

Listen to Dr Winston's approach to stopping the negative cycle of one case of lameness leading to another; by improving the way we treat lame cows.

Dr Winston Mason: Early detection and prompt effective treatment


Listen to Dr James Wilson present the latest on lameness in dairy herds, reducing future prevalence and improving lame cow outcomes.

Dr James Wilson: Lameness management on farm

Key principles to achieving better outcomes for lame cows:
MONITOR: 

Early detection is the first principle to achieving better outcomes for lame cows.

Episode 1: Reducing Lameness – Monitor

So how are lame cows detected on-farm?

●     If farmers are only looking for lame cows at the back of the herd, they will miss 40% of them.3 
●     Studies also show farmers only detect 25% of clinically lame cows when compared to a trained lameness scorer.2,
●     Delayed lameness detection will result in delayed treatment and result in poorer outcomes.
●     The farm team need to continue their daily detection of lame cows PLUS add in lameness scoring of the whole herd (ideally fortnightly), to help pick up those more subtle cases of lameness.
●     Lameness scoring is not difficult, watch the DairyNZ lameness scoring video, and get the whole farm team involved.
●     The bottom line for early detection is aim to do better than what you are doing now.
●     Once detected, lift the hoof to diagnose the cause. 80% of lameness cases are claw horn lesions (white line and sole disease).

Remember, for a faster recovery, improved reproductive performance, less culling and less future lameness, you have to combine early detection with prompt effective treatment.5,6,7,8

MANAGE

Prompt effective treatment is the second principle to achieving better outcomes for lame cows.

Episode 2: Reducing Lameness – Manage

So what does prompt effective treatment actually look like?

●     “Prompt” treatment = lifting the foot and treating the lameness ASAP after detection.  Delaying this step will = poorer outcomes.
●     “Effective” treatment = a trim, block and 3 days of KetoMax for pain relief.
●     All lameness is painful so don’t reserve blocks and KetoMax just for the ‘bad ones’.4 5 6 
●     Take a look at our ‘Making lameness treatment less of a grind’ video series to get you on the right track.

When prompt effective treatment is combined with early detection, lame cows will recover faster, have improved reproductive performance, will be less likely to get lame again, and less likely to be culled.5,6,7,8 But remember you have to do both together! 

MINIMISE

Early detection and prompt effective treatment is ONE of the best ways to minimise future lameness, but don't forget about the other risk factors on-farm, in particular reducing pressure on cows in early lactation.


Episode 3: Reducing Lameness - Minimise

So what is the biggest risk factor for lameness?

●     The biggest risk factor for lameness is a previous case of lameness.
●     That is why early detection AND prompt effective treatment is one of the best ways to minimise lameness. 

But don't forget about the other risk factors:

●     Maximise time in the paddock – less time standing on concrete and more time to lie down in the paddock = better cow comfort.
●     Calm, patient stockmanship. Don't push cows, use the backing gate sparingly.
●     Minimise BCS loss post calving by meeting BCS targets, good nutrition during early lactation, preferentially feed at-risk cows.
●     Focus on heifers/young cows, delaying the first case of lameness will reduce future lameness.
●     Maintain tracks and races so cow flow is not negatively impacted.
