1Can anyone tell me what is these cattle have in
common?
2Dehorning
3What are some reason why you would want to dehorn?
- Cattle with horns can
- cause more severe injury to other cattle,
especially in yards, feedlots and transport - damage hides and cause bruising which reduces the
value of carcasses - be potentially more dangerous to handlers
- require more space at a feed trough and on cattle
trucks - suffer discounts at sale especially if they are
destined for feedlots. - Cattle with out horns
- are more docile and easier to to handle
4When do you want to dehorn?
- It is best to dehorn calves at less than three
months of age because they are more easily
handled - Should be done on cool dry days, in late
afternoons - Should be done when fly activity is usually low
5Can anyone tell me some tools you would use to
dehorn?
- Chemical Dehorning
- Hot Iron
- Spoon/Knife or Tube
- Barnes Type Dehorner
- Keystone Dehorner
- Electric Dehorning saw
6Where to cut the horn
- The horn bud is free-floating in the skin layer
above the skull in young calves less than 2
months of age.
- As the calf grows older, the horn bud attaches to
the skull and a small horn starts to grow.
7Chemical Dehorning
- 1. Wear gloves when apply chemical.
- 2. Apply a thin layer to the horn bud.
- 3. Apply duct tape.
- 1. Wear gloves.
- 2. Apply thin layer to horn bud.
- 3. Apply duct tape.
8Hot iron
- Wood fire, LPG, Butane gas, and Electric heated
- Heat must be transferred evenly all the way
around the horn bud. - This ensures that the horn growth tissue is
destroyed. - No loss of blood, and no wound to become
infected.
9Spoon/Knife or Tube
- 1. Remove horn 1/8 horn-producing skin.
- 2. Apply antiseptic to the wound.
10Barnes-type Dehorner
- Best used on two to six months of age calves.
- Acts like scissors, place over horns.
- Once on horns pull handles apart to cut of the
horns.
11Keystone Dehorners
- Very similar to Barnes
- Very smooth, quick, easy to use, and less painful
to the animal
12Saws
- Usually for adult cattle
- Many different kinds electric, hand, and wire.
13Treatment after dehorning
- After the operation, animals may bleed freely for
a short time. - Dressing powder (dusting powder) -a powder that
contains a fly repellent is recommended if
dehorning in the warmer months when flies are a
problem.
14Treatment after dehorning
- Dehorning pads - these are placed on the wound
and reduce the amount of blood loss from the
operation. - The pads are left on the wound until they drop
off with the scab. - After dehorning, cattle should be inspected
regularly for the first 10 days and any infected
wounds treated.

17Review
- What are some tools used for dehorning?
- Chemical, Hot Iron, Spoon/Knife or Tube, Electric
saws, Barnes-type dehorners, Keystone Dehorners - What types of treatments can we apply to the
wound after we dehorn? - Dressing powder (dusting powder), and Dehorning
pads
18Review
- How often do we check on the cattle that we
dehorned? - Cattle should be inspected regularly for the
first 10 days and any infected wounds treated.
