Operating Instruction for L&H Freeze Branders
Freeze branding is a technique in which a supercold branding iron, properly applied to the animals
hide, kills the color pigment producing cells. The result is that white or colorless hair instead of
colored hair, grow at the brand site. Freeze branding is effective on both cattle and horses along
with dogs. One advantage of freeze branding is that it produces a readable brand at any time of
the year.
Skin Anatomy
The skin of the animal contains millions of hairs which make
up the animals coat. Figure 1 is an enlarges, simplified
drawing of one hair shaft with its color (pigment) producing
follicle (CF) and its growth follicle (GF), both shown below
the skin.
Under normal circumstances hair grows as a clear shaft
(like a clear straw) from the GF. On colored animals,
pigment (black, brown, red, yellow etc.) is added from the
CF below the skin to the clear hairshaft, which gives the
hair its color.
When the intensely cold iron used in freeze branding is placed on the skin for the correct time and
at the correct pressure, the cold temperatures destroys the CF's at the brand site so they no
longer can produce pigment; however, the hair still continues to grow for the GF's. The result is
that hair at the brand site contains no pigment and appears white. This is the desired result-a
uniform, white brand. If the iron is pressed to the skin for a shorter period of time and/or with less
pressure that required, some hairs grow in colored and some hairs grow in white, so the brand has
a streaked appearance. If the iron is held on a longer period of time, the cold destroys the GF's as
well, so that no hair grows at all. On light colored animals the bald is desirable because the dark
skin with no hair shows up better that a white brand.
Recommended Materials and Equipment
· Holding chute or some other positive device to keep the animal from moving
· Container large enough so the irons can stand upright when the heads are submerged in
the coolant
· Coolant-Dry Ice and Alcohol or Liquid Nitrogen
· Electric clipper (surgical blade preferred)
· Grooming brush for cleaning the brand site
· Gloves
· Stopwatch
· Squirt bottle
· L&H Brass Freeze Branding Irons
· 99.9% alcohol (lower percentages contain water which can cause an ice layer to form
during branding and decrease the penetration of the cold through the skin
