An AAEP vet explains this permanent identification for your horse.

After the area has been shaved and cleaned and the freeze-branding iron placed into liquid nitrogen, the iron is pressed firmly onto the horse for about 10 seconds.

A horse owner posed the following question to the American Association of Equine Practitioners, an AQHA alliance partner.

Question:

I am interested in freeze branding my horses. What is involved in the process? Can I do this myself, or do I need help?

Answer:

Freeze branding is a method of permanently identifying your horse. It is aesthetically appealing and is less painful than hot-iron branding. Horses generally tolerate it with minimal restraint. We recommend you contact someone who frequently does this procedure to ensure good results. Inexperience can lead to an inadequate amount of white hair in an indistinct pattern or an unsightly hairless scar.

The most important piece of equipment is a quality branding iron. It is recommended that the iron be made of brass, as the steel iron used in hot branding does not hold the cold temperature adequately. Contact a metal fabricating company to have the brand made in your design. There are commercial manufacturers that will do this.

Freeze branding is usually done in one of three places: The hip, the shoulder or the crest of the neck. The area is clipped with a #40 blade, cleaned and degreased with alcohol. The iron is submerged in liquid nitrogen to reach the temperature of minus -320º F; usually this takes about five minutes in the nitrogen. The iron is placed on the skin for approximately 45 to 60 seconds, depending on hair color (chestnuts generally require less time). Initially, the frozen skin is indented, then thaws to leave a welt. The welt lasts 15 to 30 minutes. Over the next few weeks, the branded skin will dry and scurf up. White hair will replace the original color as the new coat grows in. A good brand is bright white and crisp against the coat background.

Some states have branding laws, and it is advisable to check with your state’s branding board to make sure you are not using someone else’s registered brand.
