The dairy industry has improved by leaps and bounds when it comes to hoof health. There was a time when lameness issues were an afterthought and hoof health plans, nutrition and footbaths were considered extra expenses. Now we know that dairy cow hoof health is directly tied to profitability and performance. During my time as a hoof trimmer, all of the farms I visited implemented some sort of hoof management program ranging from scheduled trims to specially-formulated nutrition and footbaths. <\/p>\n\n\n\n

As an industry, we have fully recognized and embraced the importance of hoof health \u2013 which leads me to ask a question: Why aren\u2019t we making more progress on lowering lameness rates? <\/p>\n\n\n\n

Evolving Hoof Trimming Strategies<\/h2>\n\n\n\n

Considering all the effort dairies are devoting to hoof health, why does hoof health appear to not be improving? Lameness rates have become stagnant over the last two decades and the percentage of lameness on dairies is about 24% worldwide. While consulting on-farm regarding hoof problems and observing these concerning statistics, I began to question if hoof management methods needed to change. <\/p>\n\n\n\n

Hoof trimming strategies, like anything else on the dairy, need to evolve alongside farms. Dairies have bigger herds, bigger barns with farther walking distances and more opportunity for wear and tear on the hooves. This means that, oftentimes, we are over-trimming and exposing healthy cows to potential problems. Cows today need more hoof left on the sole and should have less trimmed off their toes when the claws measure less than 3 inches. Over-trimming leads to trauma and inflammation inside the claw \u2013 this trauma and inflammation account for almost all non-infectious claw lesions. <\/p>\n\n\n\n

It may seem like a good idea to shorten the intervals between maintenance trims. But the truth is, if someone is over-trimming the claws, trimming the cows more often will not help, in fact the problem may (will) get worse. The solution is: figure out what schedule works best to achieve low rates of lameness. Some dairies need to trim more often than others. Some cows need to be trimmed more often than other cows, due to past lameness events. The key is to figure out what works best for the cow and continually adjust the trimming schedule to continue to decrease the amount of lameness on the dairy.<\/p>\n\n\n\n

Hoof Trimming Strategies for Dairy Cow Hoof Health<\/h2>\n\n\n\n

What is the solution? Identify instances of over-trimming. To work, this must be a team effort on the dairy. Producers, herd managers, nutritionists, milkers, etc. all need to be able to recognize over-trimming and point it out when it occurs. Training the team on dairy cow hoof health and best practices allows everyone to have confidence in identifying issues and mistakes. <\/p>\n\n\n\n

As an industry, we need to support contract trimmers and help them evolve their skill set. When we learn new things about cow health and nutrition, we readily support veterinarians and nutritionists to change their approaches. Hoof trimming strategies worked better 20 years ago because dairies were different. It\u2019s time we empower hoof trimmers to evolve with the changes. Part of that is understanding what a proper trim looks like. <\/p>\n\n\n\n

The toes are trimmed flat and the heels are not lowered by trimming.  This will help stabilize the claws on concrete and maintain a good hoof angle (52-55 degrees).  <\/p><\/div>\n\n<\/div><\/div>\n\n

Claws in a high wear environment will be shorter than 3\u201d.  When the claw measures less than 3\u201d, we cannot trim the sole on the toe end<\/strong>. Because there is no overgrowth on the toes with short claws, we can only trim where the typical sole ulcer site is.<\/p><\/div>\n\n<\/div><\/div>\n\n

The outside and inside hoof walls are trimmed.  Trimming the hoof walls leads to thin soles, toe ulcers and toe abscesses. <\/p><\/div>\n\n<\/div><\/div>\n\n

Bad Trim<\/h5><\/div>\n\n\n\n

The toes are trimmed too short (less than 3\u201d) and the inside walls on the claws are trimmed. This causes thin soles, toe ulcers and toe abscesses.<\/p><\/div>\n\n<\/div><\/div>\n\n

Trimming from the heal to the toe leads to poor foot angles. This leads to an increase in white line abscesses and sole ulcers. <\/p><\/div>\n\n<\/div><\/div>\n<\/div><\/div>
