Lecture 4: intro to farriery and shoeing

well

you need to work ____ with farriers

weight bearing

what is the main function of the hoof

6-9 mm per month; about a year to regrow a whole hoof

how fast does a horse hoof grow

protective top layer of coronary band

what is the periople

kertain

what is the hoof made of

junction of hair and keratinized tissue

what is the coronary band

where the hoof "breaks over"

what is the toe

common site of cracking with imbalanced trimming

what is so important about the quarter

shock absorption by expanding and contrating with weight bearing

what is the heel used for and how

anatomy of the hoof

anatomy of the hoof

prevent heel from spreading too much

what are the bars used for

it is what suspended the entire horse

what is so important about the white line

infection of the white line

what is white line disease

anatomy of the bottom hoof

anatomy of the bottom hoof

know the sole

know the sole

structure support via shock absorption for the heel bulbs

what is the main function of collateral cartilages

ossification

what can be found in the collateral cartilage most likely from instability

sensitive and insensitive

what are the two types of lamina

suspend P3 in the hoof capsule

what is the function of the lamina

frog, shape of hoof (concave), and wall

what are the 3 parts of the hoof that help with traction

digital cushion and ability for heels to expand

what are the 2 biggest shock absorbers in the hoof

lamina

what transmits the weight of the horse to the hoof wall

periople

what protects the hoof from moisture evaporation

hoof wall

what protects the lamina

frog, digital cushion, collateral cartilages

what are the parts that makes up the peripheral pump (venous return)

6 weeks

what is the typical trimming interval of the equine hoof

difference between feet, lateral imbalance, toe wear, flare vs upright side

what are the 4 things that effect how a hoof will grow

sole is concave and wall is flat

what do you trim and equine hoof until

horse puts more pressure on longer part of the heel

why is medio-lateral imbalance so bad

underrun heels

what is this

soreness and pain

what do underrun heels lead to

toe dragging

what is happening here

lameness in that limb because front of foot is dragging

what can toe dragging indicate

long toe

what is this hoof shape

toe

with long toe, where does the force shift too

the side that bears more weight

which side of the hoof develops flares

navicular diease

what does contracted heels often indicated

don't

if the horses hooves grown different _____ force them to be the same

hoof knife and rasp

what is this

cinch cutters

what is this

crease nail pullers

what is this

hoof stand

what is this

farrier hammer

what is this

clincher

what is this

nippers = flat top and smooth end

show pullers = rounded top and ball on end

what is the main difference between nippers and shoe pullers

the hoof becomes sore

what can happen if you remove too much sole in a horse

1) nip wall to remove length

2) rasp to remove flares, level weight bearing surface, and shape hood

two large steps to trimming a hoof

balance and align the boney column

what are the two main goals for hoof trimming

pull

as a vet you should be able to ____ shoes

lameness

poor shoeing can cause ____

conformation

shoeing must accommodate the natural _____

no

are you able to fix conformation with shoeing alone

about every 6 weeks

what is the typical shoeing interval

(earliest) foot not balanced, nail clinches raised, show loose or twists, shoe or nail heads worn, hoof wall grown over shoe (latest)

what are the 5 signs a horse needs to be reshoed

nail clinches raised

what is happening here

steel

what is the most common shoe material

durable, heavy, can make from scratcj

characteristics of a steel shoe

less durable, lighter, can't be hot shod

characteristics of aluminum shoes

remove shoe, trim hoof, shape shoe, nail shoe on, set nails, cut clinches, crimp clinches, finish clinches, finish hoof

what are the 9 steps of shoeing *****

shoe shaped without heat before going on hoof

what is cold shoeing

no need for forage, cheaper, less skill

advantages of cold shoeing

shoe won't fit perfectly, harder for farrier to perfectly shape shoe

disadvantages of cold shoeing

shoe momentarily applied to hoof to shape hoof to shoe

what is hot shoeing

best fit, farrier can shape shoe better, custom shoeing available

advantages of hot shoeing

forage required, if held too long can injure tissues, takes longer

disadvantages of hot shoeing

support at heel, promotes break over, bony column aligned with dorsal hoof wall

what are the 3 signs of a good shoeing job

damage to hoof wall and pain

what are the two main concerns with removing a shoe

raise/cut/rasp off clinches, pull out nails with puller, pull shoe off from heel to toe

step to removing a shoe **

towards center and toe of foot

which direction is your leverage when removing a shoe

raising the clinches

what is happening here

cutting the clinches

what is happening here

rasping the clinches

what is happening here

pulling nails with a crease nail puller

what is happening here and with what tool

pulling a shoe

what is happening here
