The horse’s hoof is an amazing structure, with layers and layers of tissue and function. The hoof wall is the barrier between the bones inside, as well as the soft tissue structures that hold your horse up!
The hoof wall is a changing structure, as is grows about 6 to 9mm a month. In a year’s time, most horses will have totally regrown their hoof wall. The majority of tissue in the hoof wall is keratin, and it’s about 25% water. If your horse is shod, the horse shoe nails go through the hoof wall.
This hoof is coated in polish, ready to hit the show ring.
The stratum tectorium is the outermost layer, and creates a bit of shine on the hoof wall. The periople is the top 20mm or so of the stratum tectorium, and protects the coronary band as well as helping to control evaporation of moisture from the hoof.
The thickest part of the hoof wall is the statue medium. This layer is also pigmented, which gives dark hooves their color. This layer of hoof wall contains cornified skin cells, which are surrounded by horn. These structures are arranged into tubes. This part of the hoof wall bears the weight of your horse, and tends to be thicker at the toe. It functions to spring back after your horse steps down, which helps to propel him forward. Nothing can penetrate a healthy stratum medium.
The innermost layer of hoof wall is the stratum lamellatum. This layer is highly flexible, and attaches to the tender inner structures of the hoof. It does allow the pedal (or coffin) bone to more inside the hoof.
A healthy hoof wall will not have any rings or cracks. Working with a Farrier on a regular basis will help you stay ahead of any hoof wall problems. If you inspect the hooves daily while checking the digital pulse, you can stay ahead of many hoof problems.
This hoof has a shoe removed for Farrier work, before the trim.
Ichthammol is a dark and sticky black salve that draws out infections. It’s made of a base ingredient, like beeswax or paraffin, mixed with sulfur rich shale. The shale starts as sedimentary rock, and through a series of steps becomes an oil of which ichthammol is made.
Horse Hoof Anatomy - The Frog
When you look at the horse’s hoof in great detail, there’s a lot more going on than just the sole, wall, and what’s inside. The frog has some critical functions in the hoof as well as the rest of the horse.
The frog is the spongy triangular shaped tissue on the hoof bottom. The apex, or pointy part, points to the front of the hoof. The base is wider and extends out the back of the hoof. The hoof’s center of gravity is at the approximate apex of the frog.
Anatomy of the horse’s hoof - the coronary band!
The coronary band is the junction between the hair and the hoof. Seems simple enough, but the function of the coronary band is much more important. This is the source of hoof growth! Proper nutrition for your horse’s hooves starts here.
