What are the two types of branding?

The two types of branding recognized in livestock management are freeze branding and hot iron branding. Freeze branding involves applying extreme cold to the skin using liquid nitrogen or dry ice to create a permanent hair loss in the shape of a brand, which reveals white hair against the natural color of the animal's coat. This method is often less painful than hot iron branding and is less likely to cause scarring.

On the other hand, hot iron branding involves using a metal brand that has been heated to a high temperature and applying it to the skin of the animal. This method leaves a seared mark as the hair in the branded area does not grow back, thus providing a clear identification method.

These two methods are widely used in livestock identification, making them key components in the industry. The other options mention branding methods that are less commonly used or do not represent recognized types of branding within agricultural practices.
