3 WHY IS HOOF CARE IMPORTANT? Regular/Therapeutic hoof care enables the horse to stay sound to complete the job it is being asked to do Conformational defects pre-dispose a horse to injuries over the course of a lifetime, and proper hoof care can help manage/delay potential issues Keeping horses on a schedule helps to catch problems early

4 WHY IS HOOF CARE IMPORTANT? Hoof Energy Video

5 WHY IS HOOF CARE IMPORTANT? A horses foot travels 2 ½ times the speed of the horse A thoroughbred may be traveling at 30mph, his foot is traveling at 75mph The foot on a Thoroughbred racehorse will accelerate to 75mph and decelerate to 0mph, impact the ground and then accelerate to 75mph again two to three times PER SECOND!

6 ANATOMY OF THE HOOF The equine hoof is a feat of engineering,comprised of: Insensitive Structures Sensitive Structures Bones Tendons/Ligaments Intricate blood supply

7 INSENSITIVE STRUCTURES Things we can see from the outside Exterior Hoof Capsule Hoof Wall Periople (at Coronary or Coronet Band)

8 INSENSITIVE STRUCTURES Insensitive Structures (ground plane) Insensitive Sole Insensitive Frog White Line Divided into Three Zones Toe Quarter Heel

9 PARTS OF THE HOOF Buttress of the Heel White line Wall White Line Sole Frog/Apex of Frog Bars Buttress of the Heels Bulb of the Heels Central Sulcus Lateral Sulcus

10 SENSITIVE STRUCTURES Sensitive structures includes: Coronary Band Sensitive Laminae Sensitive Frog Sensitive Sole Digital Cushion Main Extensor Tendon

11 SENSITIVE STRUCTURES

12 CONNECTING THE PARTS The insensitive and sensitive structures are connected by laminae Velcro like structure that ties the coffin bone to the outer hoof wall

13 LIMB ANATOMY Sensitive Tissue includes: Coronary Band Sensitive Laminae Sensitive Frog Sensitive Sole Digital Cushion Bones include: Cannon Bone Long Pastern (P1) Short Pastern (P2) Coffin Bone (P3) Navicular Bone Tendons/Ligaments include: Deep Digital Flexor Tendon Main Extensor Tendon Suspensory Ligament Main Extensor Tendon Suspensory Ligament (Digital cushion)

15 CONNECTING THE PARTS

16 CONNECTING THE PARTS Main Extensor Tendon In charge of allowing the limb to extend forward Connects to front of P1, P2, and P3 (coffin bone) Deep Digital Flexor Tendon Allows the fetlock to sink toward the ground Pulls the coffin bone and hoof wall up onto the toe (flex) Slides past the navicular bone Connects to the back/bottom of the P3 (coffin bone) Suspensory Ligament Maintains the position of the fetlock Connects to the extensor tendon main extensor tendon

18 FACTORS EFFECTING HOOF QUALITY Environment Conformation Nutrition Genetics Pathology

19 ENVIRONMENT Wet environments produce soft, weak hooves Horses kept in wet environments are prone to: Thrush: Infection of the tissues of the frog A naturally occurring organism inside the horse. When poop packs inside the foot the infection takes place. Organism cannot tolerate oxygen regular hoof picking can discourage thrush Soft Tissue Injuries - from unstable ground

20 WET CLIMATE HOOVES

21 ENVIRONMENT Dry environments produce hard, brittle feet Horses kept in dry environments are more susceptible to impact/concussion related injuries Arthritis Ringbone/Sidebone

22 DRY CLIMATE HOOVES

23 CONFORMATION Conformation determines movement Is the result of bones, and their relationship to other bones You cannot correct a horses conformation through shoeing, you can only manage it * REMEMBER: Conformation predisposes the horse to certain types of injuries farrier manages defects

29 CONFORMATION DETERMINES MOVEMENT

30 NUTRITION Every environment has different minerals in the ground Basic vitamin supplement Hoof Supplements/Maintenance Oral, intra-muscular, intra-articular

31 GENETICS Positive and negative traits may be passed down through different breeds, or family lines Will influence conformation Size/shape of hoof Size proportionate to breed Thoroughbred vs. Quarter Horses Hoof growth Undesirable traits Club foot Digenerative tendon/ligament Color of hoof Myth Buster

32 WHAT IS A GOOD HOOF? A balanced hoof free of distortions and pathology A farrier s ability to do a good job requires: Flat area Dry area Well lit area Horse that stands perfectly still Quality hoof material An appropriate timeframe/schedule Trimming Interval determined by: Rate of growth Job Issues/distortion trying to be managed

33 BALANCE (A) Matches the angles of the bony column Pastern angle Coronary band is smooth and continuous (B) Medial to Lateral (C) Front to Back 50% ratio from toe to heel from center of weight bearing Heels to widest part of the heel Breakover

34 (A) MATCHES BONY COLUMN ANGLE (B) MEDIAL TO LATERAL BALANCE

35 (C) 50% FROM CENTER OF WEIGHT BEARING BALANCE

36 (C) WIDEST PART OF FROG/BREAKOVER BALANCE

39 FREE OF DISTORTIONS

40 FREE OF PATHOLOGY Pathology includes: Laminitis/Founder Navicular Arthritis Club foot

41 LAMINITIS/FOUNDER Due to changes in the metabolism there is inflammation in the laminae (LAMINITIS) Velcro like connection starts to die Coffin bone is no longer connected to hoof wall Deep digital flexor tendon (attached to coffin bone) tries to pull the foot up on the toe, but leaves the hoof wall behind Results in either rotation or sinking (FOUNDER)

44 THEN, WHY DO WE SHOE A HORSE? If a horse can do the job it s being asked to do without shoes, then don t shoe. Why might a horse not be able to do it s job without shoes? Sensitive feet ouchy on work surface Structurally weak feet falling apart, thin soles Weak tendons that need support Support a conformational defect Abrasive work/living conditions cause excessive wear Protect a certain part of the foot
