Dry ice can be used for freeze-branding cattle and horses.

How does freeze branding work?

Cynthia Oliver, a freeze branding specialist says, “When done correctly, freeze branding damages melanocytes (the skin cells responsible for creating colour) and results in hair that is white or gray in colour.”

How is freeze branding performed?

Animals to be branded must either be confined to a small space where they cannot move about freely or, ideally, be restrained in a neck clamp. This will help keep the animal still while being handled.

Shave the area where the mark will be placed. Keep the branding irons in the container with the dry ice and isopropyl alcohol coolant for a few minutes, or until the branding irons reach a temperature of -147 degrees Celsius, Cynthia advises.

To remove any oils or dirt that may prevent the iron from making good contact with the skin, rubbing alcohol should be used to wipe the freshly shaved area where the brand will be.

Time required for dark-colored cattle

The branding iron should be pressed against the skin for 55 seconds. The place where the branding was done will develop white or gray hair as a result.

Time required for light-colored cattle

The skin must be in contact with the branding iron for 70 seconds. This will cause no more hair to grow in the shape of the brand. This happens because the freeze-marking procedure completely destroys the hair follicle. The animal’s true white, blue or black skin will eventually be visible as the animal’s hair falls out and does not grow back.

What advantages does freeze branding have over hot branding?

Freeze branding is a stress-free procedure, according to Cynthia, because it causes no discomfort to the animal and does not require anesthesia. Calves as young as six months old and pregnant cows can be safely branded. No medical care is needed afterward because the freeze-marking procedure leaves no raw or open wounds.
