Cow hoof

A cow hoof is cloven, or divided, into two approximately equal parts, usually called claws.[1]

Lameness

Approximately 95% of lameness in dairy cattle occurs in the feet.[1] Lameness in dairy cows can reduce milk production and fertility, and cause reproductive problems and suffering.

Hoof trimming
Trimming the hoof of a cow with an angle grinder

Hoof trimmers trim and care for bovine hooves, principally those of dairy cows. Hooves were once trimmed with a sharp knife while the cow was restrained and positioned with ropes. Most large-scale hoof-trimming today makes use of angle grinders and of some type of hoof trimming crush. A hoof trimmer using modern machinery may trim the hooves of more than 10.000 cows per year. The trimmer shapes the hooves to provide the optimal weight bearing surface. A freshly trimmed hoof may be treated with copper sulfate to prevent foot rot.
