Dehorning

What 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

4
When 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

5
Can 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

Where 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.

7
Chemical 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.

8
Hot 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.

9
Spoon/Knife or Tube

• 1. Remove horn 1/8 horn-producing skin.
• 2. Apply antiseptic to the wound.

10
Barnes-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.

11
Keystone Dehorners

• Very similar to Barnes
• Very smooth, quick, easy to use, and less painful
  to the animal

12
Saws

• Usually for adult cattle
• Many different kinds electric, hand, and wire.

13
Treatment 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.

14
Treatment 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.

Review

• 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

Review

• 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.
