Grass cracks Usually superficial and thin, grass cracks are commonly experienced when horses have long, unshod hooves; environmental changes, lack of nutrition or impaired blood flow to the hoof also contribute. They often begin from the ground and move upward and are easily corrected with regular farrier work. Quarter cracks Quarter cracks usually start at the coronary band and travel toward the ground. They are caused by trauma, conformational issues and lack of regular trimming.
Landing unevenly can cause a quarter crack in the hoof. Sand cracks Sand cracks extend downward and occur after a coronary band injury or from white line disease at the coronary band. Horses that have experienced direct impact to the bar, or have weak and unbalanced bars, are more susceptible to bar cracks. How can I prevent hoof cracks? Take steps to help ensure your horse has the healthiest hooves for his ultimate performance.
Using these products will help prevent hoof cracks more than anything, that along with regular trimming and maintenance on the horse. Another option is to repair cracks and replace lost hoof wall with products that fill in the gaps with materials such as acrylic or polyurethane.
In more severe cases, the patches may be reinforced with fiberglass. The patch material will then be trimmed away as the hoof wall grows out. For the most serious cases, when a horse is significantly lame and his long-term soundness is at risk, the farrier will need to work in conjunction with a veterinarian, who can prescribe medications to relieve pain and control infections. In some cases, dead or dying tissue may need to be removed, and x-rays may be needed to look for the position and potential injuries to the coffin bone and other structures within the foot.
Even as the work to stabilize the hoof is underway, it is important to adjust trimming and shoeing to address any hoof imbalances or other stressors that caused the crack in the first place. Simply keeping your horse healthy—with balanced nutrition, not overweight, and plenty of turnout and exercise in good footing—will go a long way toward keeping his hooves strong as well. Beyond that, you can take additional steps to reduce the risk of hoof cracks:. Whether the horse is barefoot or shod, regular visits from your farrier are important to keep his feet properly trimmed and balanced in accordance with his conformation.
Flares that form at the bottom of overgrown hooves can easily form cracks. Calks, rims, borium and other traction devices may be invaluable if you often ride on slick surfaces, but they can add stresses to the hooves and legs that can lead to cracks. Your farrier can advise you on the most appropriate shoes for the type of riding that you do. A horse whose diet is deficient in important vitamins and trace minerals is likely to have weak, shelly hooves as well as dull, coarse hair.
Biotin is the primary ingredient in supplements intended to improve hoof health; many also contain minerals such as copper and zinc as well as amino acids and omega-3 and -6 fatty acids.
If you suspect your horse may benefit from a hoof supplement, consult with your veterinarian or an equine nutritionist to assess his diet and create a healthier overall ration. Fly sprays will repel stable flies, and a number of management strategies can help keep insect populations under control. These flies breed in decaying organic matter, so clean up soiled bedding and manure from turnout areas daily, and treat manure pile with insecticides or larvicides.
If flies remain a problem, consider outfitting your horse with fly boots, which cover the legs and prevent the pests from landing on your horse. Galloping over hard ground poses an obvious risk of cracks, but traveling through deep, soft footing also places stresses on the hoof that can cause injury to the hoof wall.
Out on the trail, slow to a walk when you encounter ground that is either deep and soft or hard and rocky, and drag your arena frequently to keep the footing uniform.
Horses can adapt to either condition, but alternating between the two on a daily basis can loosen shoes and cause cracks. Laying gravel in high-traffic areas may also help. Picking out the hooves is an essential part of good horsemanship, but as you do this chore, take some time to inspect the overall health of the hoof: Run your hand over the hoof wall and coronary band to feel for defects.
Look for dark spots on the sole, which could indicate bruising. Wiggle the shoe to check for looseness—if you have a farriery tool called clinchers on hand, you can tighten the clinches.
If the shoe is on the verge of falling off, your safest option may be to remove it entirely. As you handle his feet, give the hoof walls a once-over.
I got there and looked at it, and it was a scar type crack from a weakness in the wall. Behavioral Problems. Medications and Drugs. Horse Care. Farm and Ranch. Hoof Care. Injuries and First Aid. Parasite Control. Preventative Care. Cracking in the heel region might also result from a shoe that is too long—excessive shoe length creates leverage that applies excessive force to the heel region. Heel cracks might also develop due to uneven heel loading.
Bar cracks that appear in the bars the inward folds of the hoof wall, located on either side of the frog also can be painful and are usually caused by trauma e. Folded or crooked bars tend to be weaker and more prone to cracking. Your horse can overload the toe when he moves, causing these cracks.
Also, many horses with heel pain land toe first, causing extreme toe concussion—and, hence, cracking. Hoof Project Foundation head David Hood, PhD, DVM, is studying horses with a prominent crena, or notch, at the distal dorsal aspect the of the distal phalanx the lowest point on the top of the coffin bone , to determine whether a weak or absent laminar attachment from the wall to the coffin bone in this area causes toe cracks.
Quarter cracks can be the most aggravating of all hoof cracks to manage. They are usually caused by uneven foot landing, usually due to conformation defects such as carpus valgus outward deviation of the lower limb stemming from the knee, seen as knock knees or varus outward deviation of of the lower limb stemming from the knee, seen as toeing in. They can also result from many other factors such as neglect hooves can grow too long if not trimmed regularly, causing cracks and splits , imbalance when one side of the coronary band is higher than the other , coffin bone defects e.
Quarter cracks usually appear at the coronary band and grow toward the ground. These types of cracks might bleed or become infected, causing extreme pain. Your veterinarian might need to take radiographs X rays to determine the exact cause of the crack. Radiographs can reveal foreign objects in the hoof wall, coffin bone defects, or coffin bone remodeling that could weaken the wall and create cracks. Hoof abscesses can also cause cracks. If your horse has an abscess and the infection drains from the coronary band, a small horizontal crack called a cleft might appear at the hairline.
Usually, these small clefts will grow down the hoof wall with no problems as long as they are kept clean and reasonably dry. With the advent of the smartphone, it has become easy to snap a picture and send it to your farrier and veterinarian for them to scrutinize. However, if you notice any infection, blood, or lameness associated with the crack, call your veterinarian immediately.
What can your farrier and veterinarian do to help treat the problem? The first step you and your horse health-care team will likely take in this process is to watch the horse walk and trot to determine footfall. Recognize that you might need to institute environmental changes—such as eliminating extremely wet, dry, or filthy turnout or bedding conditions—before your vet and farrier can remedy the hoof cracks.
Knowing what type of feed and supplements the horse receives will also help them determine if your horse is on the correct diet to support his hooves several studies have found that biotin supplementation, for instance, can improve hoof quality. The next step is to repair and stabilize the hoof crack.
Your farrier and veterinarian might have particular methods they prefer to use for different types of cracks. More severe cracks might require corrective shoeing and stabilization techniques, such as adding clips on the shoe to either side of the crack and placing implants across the crack.
Some of the methods veterinarians use to stabilize a hoof crack involve lacing—cleaning and resecting cutting away parts of the hoof wall the crack and then drilling very small holes on each side of it. They run stainless steel wire through the holes, connecting the wires at each end and tightening them by twisting the ends together.
